You are here, inaugural schoolyard ecology data jam showcases k-12 projects.

On Thursday, June 6th, four classes that participate in our Schoolyard Ecology program gathered to share their learning from the year in an interactive and creative way at our first ever "data jam!" Including vibrant displays that showcased their work with long-term data collected by students , fifth graders taught high school participants about the phenology of their trees through games, artwork, and interactive sculpture. High Schoolers taught the 5 th  graders about their work measuring carbon storage in their forest plots, how they determined the ages of their trees, and the recurrence of beech leaf disease in their field sites. 

We were wowed by the TREEmendous creativity and data literacy on display. Thank you to the students and teachers from JR Briggs Elementary School in Ashburnham, Quabbin Regional High School in Barre, St Mary's Parish School in Westfiled, and the O'Hara Nature Center in Irvington, NY.

Call for High School Projects

Machine learning for social impact .

The Thirty-Eighth Annual Conference on Neural Information Processing Systems (NeurIPS 2024) is an interdisciplinary conference that brings together researchers in machine learning, neuroscience, statistics, optimization, computer vision, natural language processing, life sciences, natural sciences, social sciences, and other adjacent fields. 

This year, we invite high school students to submit research papers on the topic of machine learning for social impact.  A subset of finalists will be selected to present their projects virtually and will have their work spotlighted on the NeurIPS homepage.  In addition, the leading authors of up to five winning projects will be invited to attend an award ceremony at NeurIPS 2024 in Vancouver.  

Each submission must describe independent work wholly performed by the high school student authors.  We expect each submission to highlight either demonstrated positive social impact or the potential for positive social impact using machine learning. Application areas may include but are not limited to the following:

• Agriculture
• Climate change
• Homelessness
• Food security
• Mental health
• Water quality

Authors will be asked to confirm that their submissions accord with the NeurIPS code of conduct and the NeurIPS code of ethics .

Submission deadline: All submissions must be made by June 27th, 4pm EDT. The system will close after this time, and no further submissions will be possible.

We are using OpenReview to manage submissions. Papers should be submitted here . When registering for a new OpenReview profile, you can type in the name of your high school as the institution and “high school student” as the role. Submission will open June 1st.  Submissions under review will be visible only to their assigned program committee. We will not be soliciting comments from the general public during the reviewing process. Anyone who plans to submit a paper as an author or a co-author will need to create (or update) their OpenReview profile by the full paper submission deadline. 

Formatting instructions:   All submissions must be in PDF format. Submissions are limited to four content pages , including all figures and tables; additional pages containing only references are allowed. You must format your submission using the NeurIPS 2024 HighSchool style file using the “preprint” option for non-anonymous submission. The maximum file size for submissions is 50MB. Submissions that violate the NeurIPS style (e.g., by decreasing margins or font sizes) or page limits may be rejected without further review.  Papers may be rejected without consideration of their merits if they fail to meet the submission requirements, as described in this document. 

Mentorship and collaboration:  The submitted research can be a component of a larger research endeavor involving external collaborators, but the submission should describe only the authors’ contributions.  The authors can also have external mentors but must disclose the nature of the mentorship.  At the time of submission, the authors will be asked to describe the involvement of any mentors or external collaborators and to distinguish mentor and collaborator contributions from those of the authors.  In addition, the authors may (optionally) include an acknowledgements section acknowledging the contributions of others following the content sections of the submission. The acknowledgements section will not count toward the submission page limit.

Proof of high school attendance: Submitting authors will also be asked to upload a signed letter, on school letterhead, from each author’s high school confirming that the author was enrolled in high school during the 2023-2024 academic year.

Supplementary artifacts:   In their four content pages, authors may link  to supplementary artifacts including videos, working demonstrations, digital posters, websites, or source code.  For source code, this can be done by, for example, uploading the code to a free  https://github.com/  repository and then including a hyperlink to that repository in the submitted paper. Data files that are not too large can also be uploaded to a GitHub repository, and larger files can be uploaded to a free research data repository like  https://dataverse.harvard.edu/ . Please do not link to additional text. All such supplementary material should be wholly created by the authors and should directly support the submission content. 

Review process:   Each submission will be reviewed by anonymous referees. The authors, however, should not be anonymous. No written feedback will be provided to the authors.  

Use of Large Language Models (LLMs): We welcome authors to use any tool that is suitable for preparing high-quality papers and research. However, we ask authors to keep in mind two important criteria. First, we expect papers to fully describe their methodology.  Any tool that is important to that methodology, including the use of LLMs, should be described also. For example, authors should mention tools (including LLMs) that were used for data processing or filtering, visualization, facilitating or running experiments, or proving theorems. It may also be advisable to describe the use of LLMs in implementing the method (if this corresponds to an important, original, or non-standard component of the approach). Second, authors are responsible for the entire content of the paper, including all text and figures, so while authors are welcome to use any tool they wish for writing the paper, they must ensure that all text is correct and original.

Dual submissions:  Submissions that are substantially similar to papers that the authors have previously published or submitted in parallel to other peer-reviewed venues with proceedings or journals may not be submitted to NeurIPS. Papers previously presented at workshops or science fairs are permitted, so long as they did not appear in a conference proceedings (e.g., CVPRW proceedings), a journal, or a book.  However, submissions will not be published in formal proceedings, so work submitted to this call may be published elsewhere in the future. Plagiarism is prohibited by the NeurIPS Code of Conduct .

70 Best High School Science Fair Projects in Every Subject

Fire up the Bunsen burners!

The cool thing about high school science fair projects is that kids are old enough to tackle some pretty amazing concepts. Some science experiments for high school are just advanced versions of simpler projects they did when they were younger, with detailed calculations or fewer instructions. Other projects involve fire, chemicals, or other materials they couldn’t use before.

Note: Some of these projects were written as classroom labs but can be adapted to become science fair projects too. Just consider variables that you can change up, like materials or other parameters. That changes a classroom activity into a true scientific method experiment!

To make it easier to find the right high school science fair project idea for you, we’ve rated all the projects by difficulty and the materials needed:

Difficulty:

• Easy: Low or no-prep experiments you can do pretty much anytime
• Medium: These take a little more setup or a longer time to complete
• Advanced: Experiments like these take a fairly big commitment of time or effort
• Basic: Simple items you probably already have around the house

City of Decatur constructing multiple recreation projects for the summer

DECATUR, Ala. ( WAFF ) - The City of Decatur is working on four new recreation projects, including an indoor tennis/pickleball court, event center, ball field complex and even a rec center.

These projects will replace the old Rec Centers that were built in the 70s.

The city will open its new centers at peak times with indoor tennis and pickleball court expected to open by the end of summer and the ball field complex to be ready for softball season.

The indoor tennis and pickleball courts will allow residents to play in a controlled environment.

For those who enjoy the outdoors, the new ball field complex will have multifield complexes for soccer, lacrosse, and softball teams.

Jason Lake, the Director for Parks and Rec, said they hope to have the ball field complex ready for the Dixie girls’ softball season.

“When the aqua dome fields went away, they lost their home fields,” Lake said. “And they’ve had to go to several different places. And it’s been very frustrating. And we know that they’ve dealt with it. They’ve been super great dealing with what they’ve had to deal with, while all this has been going on. But nobody deserves those fields more.”

The event center will replace the Point Mallard Ice Complex.

It aims to enhance what was already one of the most popular summer event centers in North Alabama.

“The event center is a 25,000 square foot event floor, with four breakout rooms and a large lobby area,” Lake said.

The rec center is still in the planning stages. Officials are still working on the bid documents.

Lake said the tennis and pickleball courts will be in clear-span buildings.

“All of the metal in that building has a 50-year warranty, the outside structure on it has a 20-year warranty,” Lake said. “So if you look at the maintenance cost over a 10-20 year period, compared to a brick and mortar building. It’s significant cost to the city and we’ll be able to save over the life of those buildings, compared to how we’ve done that in the past.”

The costs of these projects are being handled, but the cost of materials keeps going up.

“Things are priced higher than they were,” Lake said. “Sometimes things aren’t as easy to get as they used to be. We have had to deal with that. The biggest part of making those decisions and doing them in a beneficial way is to make sure everybody is communicating with the people that are responsible.”

Lake said the recreation buildings have remained relatively the same over the years.

“It’s just that when you see not as many people maybe utilizing them like they did in years past, you know, you need to be thinking about what you need to do for future growth and what our community wants at the end of the day, because they’re the ones that are using it,” Jason said.

Lake says these projects are predicted to be completed by the fall. However, the rec center is still in the planning stages. Officials are still working on bid documents.

Local News | Hinsdale District 86 school board approves ADA settlement with former Hinsdale South band director

In August 2020, Hickman suffered a stroke, leaving him with physical disabilities and some cognitive challenges, according to court documents. Upon his return to work, Hickman claims he was denied reasonable accommodations, and suffered a hostile work environment.

Hickman was fired in March 2022, a month later he filed a lawsuit against the school district, school board, and Hinsdale South, alleging they violated the Americans with Disabilities Act (ADA) and Human Rights Act.

Judge Edmond E. Chang, with the U.S. District Court for the Northern District of Illinois, allowed the case to move forward, but dismissed all claims of violating the Illinois Human Rights Act, as well as the claims against the district and Hinsdale South, leaving to the school board to settle the remaining ADA claims.

In a 4-0 vote, members Catherine Greenspon, Peggy James, Heather Kartsounes and Jeff Waters approved the settlement; members Asma Akhras, Abed Rahman and Terri Walker were not present during the June 13 meeting.

The Board has not commented on the settlement, and the District has not provided documents related to the case.

In the last year, the school board has approved a settlement agreement with former superintendent Tammy Prentiss, and the school district paid $45,000 as part of a settlement with the mother of a Hinsdale South basketball player .

10 Awesome Biology Experiments Ideas For High School Aspirants

Science is no fun without practical experiments. Unlike middle school, where you limit your study and inquiry of science to the theoretical realm, high school has a different scene. Experiments are a major part of studying science in high school, and biology all the more so. Biology is fascinating. It makes us wonder at the complex system which makes the human body function efficiently; it has all the answers to the questions of death, sickness, and life. But we must admit that only the theoretical explanation of these complex concepts never suffices to give us a satisfactory understanding. That is where practical experiments come to the rescue. 

Therefore, this post will cover 10 fascinating biology experiments that high school students can do independently, even at home. 

Cool Experiments To Do In Your Bio Lab

While many are intrigued by art competitions , others are moved toward robotic classes. However, in a bunch of students, there are a few who love biology experiments. Hence, here are a few experiments that can be tried out by high schoolers if biology is the subject that piques their interest:

1. Extract DNA

Everyone knows DNA is the agent behind our hereditary traits. Residing in the cell’s nucleus, it guides major aspects of our physiognomy. Usually, the DNA is not visible to the naked eye, you need a powerful microscope to view it, but with this experiment, you can have a fine look at the DNA with this DNA extracting experiment. 

Basically, you will be forcefully breaking down some cell walls of the extracted cells by dipping it into your extraction solution. Adding 35ml of dish soap and 5gm of salt in 240 ml of water will give you the extraction solution. Dip and mix some mashed banana slices into the extract, leading the DNA to head out into the solution. Then we will use some alcohol to force the DNA to join up into large chains that we can actually see. You will get a fluffy white substance, the DNA that is visible to the naked eye, made possible by this extraction experiment. 

2. Dissect A Flower

Everyone has theoretically seen and known the different parts of a flower. Some exceptional students might even have that picture inscribed in their memory. Very well if you have that, but the hands-on experience of viewing those parts with your own eyes can definitely beat any other theoretical picture-viewing experience. 

So, first thing first, go out and choose a bloom. Observe the flower and point out the petals, stamen, and pistil. Use a razor to remove the stamen and observe the Filament and Anther under magnifying glasses. Wipe out some pollen grains and have a detailed look at it under the microscope while you are at them. Next up, remove the pistil and observe your flower’s ovary, stigma, and style with a magnifying glass. This is the simplest yet a fascinating experiment on the list. 

3. Raise A Butterfly

Again, we have the theoretical knowledge of the life cycle of a butterfly. Yet it takes us by surprise and wonder when we see the process through our own eyes. So, get ready to be fascinated by a butterfly’s journey from an ugly worm to a colourful butterfly. 

The process is easy. You get a caterpillar, observe it daily, and note the changes. The changes will be as precise as your books have always told you. First off, a butterfly lays an egg and a caterpillar hatches from the egg. The caterpillar eats and grows, shedding its skin several times to accommodate its growing belly. Once the caterpillar reaches the right size, it sheds its skin for the last time, revealing the chrysalis, which quickly hardens. Inside the chrysalis, the caterpillar goes through metamorphosis and changes into a butterfly. At the right time, the butterfly breaks out. It hangs onto the chrysalis for a bit, just until its wings dry out and harden. Then, it flies off in search of nectar. 

So, in the end, you will be sitting back and enjoying the release of the butterfly you raised with your own very hands.   

4. Frog Dissection

Dissecting a frog is one of those lab activities that fascinate and chill you simultaneously. But before you start with the dissection, make sure you take note of all the outer organs like the skin, legs, head, digits, and urinary outlet (cloaca) of the specimen. 

You will need a good scalpel, pins, and a dissection tray to cut the frog. After these things are in place, you are all set to perform the three significant incisions on the specimen. Start by cutting from the jaw to down between the legs, then make two horizontal incisions, one above the neck and the other towards the bottom of its legs. At this point, you will start seeing some organs residing in the abdominal cavity. Repeat the same incision on the frog’s abdomen to open the abdominal cavity. Observe the heart, and identify the major organs like the liver, stomach, intestines, and oviducts. 

This experiment will definitely leave you amazed at the complex system of nerves, muscles, and bloods that functions interdependently to sustain a living being. However, this experiment should be done in front of teachers and professors in the lab.

5. Diversity Among Plant Samples

Another simple biology experiment involves going into your natural environment, such as a local park, to observe diversity among plant samples. To make the experiment more detailed, students can rub collected samples on filter paper to observe which plants present which colors. 

Teens can work to find out why certain plants present certain colors. They can also dissect the flowers of the plants and paste the dissected parts of the flowers in their observation notebooks to make a note of the differences between the flowers of the different species of plants. 

6. Yeast Experiment

Another simple and easy experiment on the list for high schoolers is the yeaThis experiment is easy because it only involves taking out four different food samples on different plates and a long-time observation of the mold that grows on each sample. 

Studying mold is an excellent way to learn more about ecology and biology. This experiment compares how fast mold grows on different types of foods kept in many American homes. Some of the foods are generally kept in refrigerators to extend shelf life, while others are commonly stored at room temperature. This experiment shows that certain foods grow mold faster than others, which is one reason why these foods are often kept in the refrigerator. 

Going a step further, the students can also do research inspired by this experiment and find answers to questions such as: what makes a mold grow? And how does one prevent their growth?

7. Look at cell division under the microscope

Cheap digital microscopes with high magnification power that can be directly connected to your laptop or smartphone are easily available in the market nowadays. You can make use of such microscopes to observe every little thing you find at home or outdoors.  

A great experiment to do at home with a microscope is to look at how cells divide in different organisms. One of the easiest is baker’s yeast. With a magnification of at least 400x, you can start discerning the shapes of individual yeast cells in water. You will notice that some of them have little buds on them, which is the way they grow and divide. 

Taking it one step further, you can also take the tip of the onion’s root and observe them to study the different stages of mitosis as well. 

8. Ferment your own food

Bacteria and yeast are practically geniuses in the art of fermentation. Humans have been taking their help for the longest time to make food items such as bread and alcohol. And it is quite easy to ferment your own food at home. 

In most cases, you need a starter culture of the bacteria or fungi that make the food you will be fermenting. You can get it from someone already doing fermentation at home or buy it online. Many options range from kombucha, kefir, or mead to yogurt, cheese, kimchi, and sauerkraut. Each fermented food has different requirements, so ensure you have everything you need before starting. After you have everything in place, you are ready to experiment with this fermented food and its varied tastes. 

9. Examining Fingerprints

The tips of each finger of your hand have a combination of lines and features in distinctive patterns that we call fingerprints. Fingerprints are one of the fascinating features of the human body. We have been told that each of us is unique in our light, and our fingerprints prove it to be so. You can analyze your own uniqueness by analyzing your very own fingerprints in this project. All you need is paper, magnifying glass, and stamp ink.

First, you need to press a finger against the ink pad and then against a piece of paper. Then, use the magnifying glass to examine the fingerprints and look for arches, whorls, and loops. You can record your finding on your paper. And then take a friend’s fingerprints to analyze the differences. 

10. Create A Fall Leaf (Or Signs Of Spring) Journal

Biology is all about studying life and learning more about our natural surroundings. A Fall Leaf journal or a Signs of Spring journal will help your students learn about the trees and bushes that are in your area. This experiment is easy, needs minimal effort, and is fun and exciting as well. 

Things To Remember

Science experiments are interesting by nature, but this aspect of their nature shouldn’t keep us from maintaining our share of vigilant caution. Science experiments could sometimes wreak havoc if we do not take enough caution while doing these experiments. Therefore, in order to prevent yourself from ruining your own experiments, you have to follow some safety instructions while doing these experiments. 

Wear covered shoes and long pants while performing any experiment, and keep your hair up so it can’t fall into your experiment or a flame. Don’t carelessly sniff or taste any chemicals; don’t just experiment with everything you get your hands on. Make sure you have your full attention in the experiments, and handle everything with care, especially sharp objects like knives or objects that could produce a flame. And at the end of your experiment, you should also know how to dispose of the waste properly. 

In the end of it, what matters the most is that we genuinely imbibe the lessons that we learn from our experiments. These biology experiments will get you further into the fascinating world of biology. If you want to further your knowledge, you may also visit science labs, perform science experiments in the lab, attend workshops and seminars, and meet people and learn from their experiences. 

Keep learning, keep experimenting, and keep enjoying the process of learning.

The High School Experiment

On the importance of labels and the fifth period bell..

When the bell rings after fifth period it’s time for lunch, for many high school students this is a relief and a blessing enjoyed with social time and tasteless food, and for many others it is another god-awful forced semi-social experience, complete with unappetizing cuisine to enhance miserable subtleties. For me, it is a time at which I sit next to my best friend, steal a banana off his plate, and talk wildly to 7 other people I hardly know. In the immediate hierarchy of friendship they would fall next on the list. Many of them could be considered popular, or “the in crowd” as it were. To be totally fair there isn’t much of a popularity struggle here at my school, and for the most part the “popular” ones are very amicable people who happen to have fair few friends; it’s not quite so interesting as fighting off Regina George for my seat at the lunch table, but it is what it is.

When I sit at lunch, next to my best friend, munching off whatever scraps he leaves because I’m either too lazy or not hungry enough to make the 40 foot trek and get my own food, when I talk to these seven other people about their recent exploits, returning sarcastic banter and laughing about nothing, we do an interesting thing.

First, however, introductions. To start, there’s number 1, my best friend, a flamboyantly gay blond pretty boy with a solid heart, a great smile, and a dying dad. Next, number 2, a gorgeous sandy-haired vegetarian with an incidentally mediocre boyfriend a year older than her. Number 3, a 6’4″foul-mouthed class clown, who’s always got a great joke, and admits to pretty girls that he’d rather have them than his actual girlfriend, on account of her looks, of course. Number 4, another tall blonde kid with a love for the saxophone and a bit of a lisp. Number 5, our own little Hispanic genius, 2nd in our class, ever-friendly, who just can’t manage to stop tripping over himself for the girl who broke up with him two months ago, and probably cheated on him. Number 6, a future navy officer, with above average grades, above average charm, above average prospects, and an above average girlfriend, I feel he may think about hurting himself sometimes. And finally, number 7, quite possibly my favorite person on the planet, an overworked, dance captain, drum major, student council member, acting, singing, caring, chaste,  hyper-feminist, 17 year-old catholic prodigy.

And this is what we discuss every single day. Our labels. How they’ve changed, how we’ve decided to drop one or add one, switch with someone else, become something different, better or worse than the day before. It’s not a new thing, we’re all seniors, we all have college and a semi-bright future ahead of us, and it’s absolutely the perfect time to have a self-perpetuated identity crisis. We’re not old enough to splurge on a sports car, we’re not so young that people don’t take our understanding of self seriously, we’re all curious, vaguely upset, and completely able to comprehend what each other person is going through.

It’s a formative year, the last one most of us have to call ourselves kids, if we still find the moniker desirable, and the ever-present fear of both time and mortality is finally deciding to set in. The fear rises in the back of your head as you realize this is going to be our last homecoming, our last lunches together. The last times that we have to ask to use the restrooms, and the last time we get to go to school for free. Scary doesn’t begin to describe it. Perhaps I’m more sensitive to these changes than others, or perhaps we all just hide it from one another, but either way, time is fast approaching and we’re all trying to figure out what to do with what’s left on the clock.

Though it seems like I’m going somewhere here, there isn’t much of a moral or theme to this story, as a first post, it serves mainly as an introduction. It serves to present my situation in a more or less reasonable way, and to put my own feelings (the ones you’ll actually be hearing) in relativity to those around me. The problem that arises in this is that I’m not a particular fan of labels, but they happen to be the way that I’m introducing everyone else. And I think that a couple put on me before we get underway is a great get-to-know-you exercise so, no matter, here we go. 

I am a high school senior from Texas. I prefer to not disclose my name, for personal reasons, (getting intimate with a bunch of strangers is far easier than doing it with actual people). I am male. I like to write. I’m starting my college applications. I believe in the Oxford comma more than I believe in myself. I have a huge issue with keeping myself close to people. I’m exceptionally insecure and sometimes find myself bagging on others because of it. Of my few blessings, I’m fairly self-aware. I’ve had one girlfriend (of three weeks, I didn’t like her much anyways but at this point I regret breaking up with her.)  I haven’t had my first kiss, I’m a virgin (needless to say), and this blog is my experiment, in openness, sharing, and sustaining the glory days. 

For posterity’s sake, this is my High School Experiment. 

Let’s do this, I guess.

A man got himself reincarnated into the world of Draconic Deus as the son of a small noble devil in the underworld. As he was expecting to live an easy and peaceful life, he ended up being forced to fight a snobbish devil in a fight to keep everything that he could get for himself. Sounds annoying. At least he can get himself a harem of beautiful women who will wholeheartedly serve him with a smile on their faces. Using his pieces of knowledge about the world and the future itself, he thinks he can make it somehow. Note: - Chapter with Naughty Scene will be marked with + in the chapter title.

[Reincarnation Centre] [A place every person who naturally reincarnates must go through, regardless of their world or situation, and as long as they're getting reincarnated, they must pass through this place, although their memories of this place are erased.] [The only two ways to enter the reincarnation centre are either destiny, like most protagonists, or having too many Karma Points for your world to be able to manage your soul’s reincarnation.] One day, a soul with an overwhelming number of both Positive and Negative Karma Points arrived at the Reincarnation Centre, enough to even shock the Manager of the place. “You... What the hell was your occupation?” That was the only thing the person in charge at the Reincarnation Centre could ask after looking at the soul’s Karma Points. The soul smiled and politely replied. “I was a doctor, a really good doctor.” And so, his life in an unknown fantasy world filled with mysteries and danger began.

100+ labs, activities, and science experiments for middle and high school students

Updated: Sep 12, 2023

Looking for fun and engaging lab ideas for use in your science class? You've come to the right place. Here's my list of practical activities and experiments you can try with your students, all in one place.

Introduction

I've been teaching MYP science (grades 6-10) internationally for over a decade. I try to devote about a third of my class time to experimental activities, which means we do a lot of labs. I'm also the only lab technician at my current school, so I'm responsible for set-up and cleanup as well. Needless to say, I've accumulated quite a bit of experience in the lab and can confidently recommend all of the following experiments. I have personally tried all of them with my students and in most cases have been conducting them for years.

Where can I get these labs?

Although I have provided links to just about every activity on my list, some are much better than others. You will often need to adjust them significantly for your classroom depending on the classes and number of students you teach, as well as the materials you have access to. Additionally, free lab guides usually do not include much in the way of background info, student questions or handouts, and teacher prep notes. For these reasons, I've created my own resources for most of the labs I do, which I'm currently in the process of uploading to my TPT store . You can access my complete experimental resource collection here . I'm adding new experiments regularly, but early purchasers will have access to all future activities at no additional cost! As you can see from the list below, I have quite a few more to add! Links to my individual lab activities have also been provided in the relevant sections.

The following list of experiments is organized by grade and unit. Click on the links below to jump to the section you need.

Scientific Method

Chemical and physical changes, characteristics of living things, earth and space science, objects in motion, atoms and elements, inheritance, earth systems and cycles, energy, work, and power, human impacts on the environment, electromagnetism, communication, body systems, organization of life, chemical reactions and bonding, forces and structures, pure substances and mixtures, health and disease, electricity, environmental chemistry, space exploration, organic chemistry, genetics and reproduction, radiation and radioactivity.

You can also access unit plan outlines for each of the above units in my store .

List of Experiments

1. Memory experiments - How many random words or objects can students memorize? Will students be able to identify a missing object (or classmate)? How reliable is eyewitness testimony? These are excellent activities for getting students to practice basic experimental design, as well as practical skills like collecting and analyzing data. As a bonus, many of these experiments require virtually no prep for you!

2. Accuracy and precision experiment - For this activity, all you need is a target and something that will stick to it. I've used a dart board, NERF guns with suction cup darts, or just a target drawn on the whiteboard with magnetic disks to throw at it. You could even make a target on the ground outside and have your students toss beanbags at it. Anything will do! Students take turns hurling things at the targets and recording the distance to the middle. Then they analyze the results in terms of accuracy (average distance to the center) and precision (range, standard deviation, and the number of decimal places).

3. Baking science experiment - I've long been a fan of incorporating food science into science class. What better way to get kids excited about chemistry while also learning a useful life skill? I've done many versions of this activity, but it always involves baking something, like cookies or cakes, by modifying a recipe to learn about variables. There are also many opportunities here for unit conversion practice.

4. Fire triangle oxygen experiment - For younger students who may not have had access to open flames before, this is a good place to start for developing safe handling practices. Students use candles and various glass containers to measure how long a flame will burn in a limited oxygen environment. You might as well demonstrate the rising water trick too since you're using all the same materials.

5. Bunsen burner temperature experiment - Students learn how the Bunsen burner works and attempt to find out what part of the flame is hottest. You'll need a temperature probe rated for high temperatures in order to get accurate data for this lab. Alternatively, you can just use a thin steel rod or a nail by holding it in different parts of the flame and recording any colour changes. Try comparing the orange and blue flames, as well as the top, bottom, middle, and sides of the flame. Almost all students fail to predict where the hottest region will be!

6. Fire extinguisher safety activity - You'll need to get some safety approvals for this one, but I think it's worth it. Who knows when you might have a real emergency to deal with? Go outside and start a simple fire in a safe place like a metal tray. Then use one of the school fire extinguishers to put it out. Have a few students try it, too. Discuss the locations of fire extinguishers, different types of fires, exit strategies, and so on. You may even want to coordinate with the local fire department and see if they can send someone to talk to the students about fire safety.

7. Lab equipment identification quiz - Another one for younger students who are just beginning to do lab work. Collect one piece of glassware or lab equipment for each student in your class (with a few extra, just in case). Put one on each desk before your students arrive. As students come in, give them a blank piece of paper and have them write down the name of the equipment in front of them. Then rotate to the next seat and repeat. Set a timer for ~30 seconds to keep things moving. You may also want to get students to draw the equipment as well, in which case they would need a bit of extra time. This works best as a review activity, but it can also be used as a chance to see what students already know.

8. Oobleck states of matter activity - After students have learned about solids, liquids, and gases, whip up a batch of oobleck (cornstarch + water) and have them explore its properties. Is it a solid, a liquid, or a bit of both? Have your students consider the particle interactions going on in this unusual fluid. A bit of research may be required on their part.

9. Salt or sugar crystal lab - Students dissolve and then evaporate a very small volume of concentrated salt or sugar solution to produce crystals. I prefer salt since it is less of a sticky mess, but you can do one or both. Check out the crystals under the microscope and compare them to mineral crystals if you have some to observe. You can also use this lab as a chance to explore saturation and give a really cool supersaturation demo using sodium acetate. Just Google 'hot ice'!

10. Separating salt and sand mixtures experiment - Give students a sample containing salt, sand, and (optionally) iron filings. Then tell them to figure out how to separate each substance. This will involve a combination of magnetism, dissolving, filtration, evaporation, and so on. There is more than one way to accomplish this task, which is what makes it interesting. Add to the challenge by having students compare the mass of their sample to the total mass of each separated substance (you'll need to allow time for proper drying) to see who managed to preserve the most material. Discuss industrial and everyday applications of these separation techniques.

11. Diffusion of potassium permanganate - Another classic chemistry experiment that involves the movement of purple crystals as they dissolve in water. You can have students record the time it takes to produce a uniform solution and then compare this at different water temperatures or volumes. It's also useful to get your students to take photos, or better yet, videos of the process to compare.

12. Dissolving cocoa experiment - Students try to find the best way to dissolve a specific quantity of cocoa in order to make hot chocolate effectively. This is great for winter or during the holiday season, but as far as I'm concerned there's never a bad time for hot chocolate. Make this as open-ended as you can, but have students write down their reasoning and the method used. Is it better to use milk or water? Should you add the liquid first or the powder first? How does the temperature affect how easily the cocoa dissolves? Obviously, you wouldn't want to use typical chemistry glassware for this one, so plan ahead if you want to allow your students to drink their creations.

13. Pond organisms microscope lab - Visit a local ecosystem and collect some water. It's better to get the 'chunky stuff' including mud, water plants, pond scum, and other organic material. Bring it back to the lab and have your students look for microorganisms under the microscope. With luck, you will be able to identify water fleas, vorticella, euglena, and other organisms in your samples. If you do this in the spring or summer, various insect larvae will likely be present as well.

14. Specialized cells microscope lab - Sure, you can easily find prepared slides of specialized cells, but it's much more interesting for your students if they create their own. Collecting cheek cells is simple, and I think students get a kick out of seeing their own cells for the first time. Root hair cells and leaf cells are easy to locate as well, although the species you choose makes a huge difference. Try a few and see what works best.

15. Energy in food (calorimetry) experiment - I've found this lab to be notoriously difficult unless you have very good equipment, but it has the potential to produce lots of interesting results and is endlessly customizable for your students. The flexibility alone makes it worthwhile to try, even if the results don't end up being as useful as you'd hoped. Burning sugary or oily foods works best. Try potato chips or marshmallows.

16. Comparing fuels experiment - In this lab activity, students burn equal quantities of various fuels to determine which makes the best fuel. Alcohols including methanol, ethanol, and propanol should be easy enough to obtain. The experiment itself is pretty straightforward, but there are a lot of factors to consider. Which fuel burns the hottest? Which burns the longest? Which is the cheapest or easiest to obtain? What about other factors, such as the smell? There's a lot for students to explore here.

17. Design a solar oven - This is an excellent project for students to tackle that requires only a few simple craft and household supplies. As a summative assessment, students can make use of their physics knowledge to conduct, reflect, insulate, and ultimately cook simple foods. I prefer not to tell them the exact method so that they can find out what works and what doesn't. We like to make s'mores and cheese toast - things that are still delicious even if they don't cook properly!

18. Thermal conductivity experiment - This lab has many variations, but most involve comparing the ability of different metals to transfer heat. If you can find wires of equal diameter and length made of copper, steel, etc. then it is pretty easy to compare the conductivity of these substances by putting one end in hot water and then measuring the temperature along its length using a digital thermometer. Alternatively, put the other end of the wire in cold water and measure the temperature after a given amount of time. The warmest liquid should indicate the best conductor.

19. Insulated drink experiment - This is a bit like the solar oven experiment, except that in this case, students are given a hot beverage and tasked with keeping it warm for as long as possible. Similar ideas and materials can be used, so it makes sense to do this as a follow-up experiment to that. Provide each group with a cup of boiled water and identical materials in order to make it a fair comparison. Then pop a thermometer in and see who has the warmest drink by the end of class.

20. Mark-recapture simulation - This mathematical exercise involves students estimating a population's size by 'marking' and 'capturing' beans or other small objects from a container. Various sample sizes are used to show how accuracy improves with the number of marked and captured individuals. Then discuss how accurate mark-recapture studies would be for different populations in the wild.

21. Quadrat study - Using square frames, students collect data on the plant or invertebrate species found in a local environment (the school playground will do!). They can use this information to estimate population sizes and species distribution, but it can also be used to identify possible community interactions, including competition, mutualism, commensalism, and predation.

22. Mesocosm experiment - Students set up small ecosystems in jars or soda bottles to observe nutrient cycling in action. If done well they can last for years. I've tried aquatic ecosystems with fish in the past, but for ethical reasons, we pretty much stick to plants and soil organisms only these days. I also like to keep it simple and do everything in large peanut butter jars. It can get pretty elaborate if you decide to make full eco-columns though.

23. Personal impact experiment - This is an open-ended investigation where students decide on a lifestyle change they will maintain for a few weeks in order to reduce their environmental impact. This could include things like reducing shower time, air drying their clothes, biking to school instead of getting a ride, and so on. They then attempt to estimate the impact they are making in terms of environmental and economic savings, both for the project duration and for a lifetime, if they were to keep it up indefinitely. Although most students quickly fall back into their regular routines, a few do recognize that small changes are manageable and decide to make compromises in the way they live.

24. Solar system scale model - This is a mathematical/visual investigation that shows kids the true scale of the solar system (it's mostly empty space!). We usually do this on two different scales - one that allows us to fit the solar system within the classroom, and another that requires us to go outside and cover some distance on the playground. Even at that scale, the largest planets are still only the size of a small ball and the Earth is minuscule.

25. Chocolate rock cycle - The rock cycle can be a bit dull and abstract considering the time scales and forces students are expected to imagine. Spice it up a little with the delicious addition of chocolate! Through mixing, grating, melting, hardening, and other processes, you can mimic most of the changes in the rock cycle and give students a clearer understanding of igneous, sedimentary, and metamorphic rock formation. Yum!

26. Rock and mineral identification with dichotomous keys - Once students have a grasp of the rock cycle, it's time to get them familiar with some of the more common rocks and minerals. This can be done outdoors with field guides and cameras, or inside with samples and a dichotomous key. Even with a key this can be pretty challenging and there is quite a bit of terminology to understand, but I still think it's worthwhile. Some kids get really into it!

27. Flashlight moon phases activity - With a couple of balls, a flashlight, and a darkened room, you can put small groups of students to work trying to simulate the movements of the Sun, Earth, and Moon as they orbit around each other. It is pretty funny watching kids trying to move everything correctly and position themselves to see the phases properly, but I think it gets the concepts across quite well. You can also simulate eclipses, and if you're feeling really ambitious, you can get Mars involved and demonstrate retrograde motion.

28. Human body systems of measurement activity - I use this exercise to teach students about units and what they are based on. In ancient times, a lot of measurement standards were based on the distances between or across body parts, including the hand, fingers, and arms. Most of the metric units in use today are based on much more complicated standards, but it can be surprising for students to realize that measuring devices can't really be made without standards of some kind.

29. Comparing ancient and modern maps - In the age of discovery (~1400-1600) a lot of early mapping was accomplished by Europeans. It wasn't all accurate, however, for a variety of reasons. This activity gives students a good crash course in cartography, which you might argue is more appropriate for geography and social studies, but it works well for this unit because it devotes a significant amount of time to understanding how we determine our location in space. Graphing using GPS coordinates is a significant part of this investigation.

30. GPS pathways activity - Since practically all of your students have access to an accurate GPS device of their own, this once-expensive activity is now easier than ever. You can use one of a handful of apps to track students as they walk various pathways around the schoolyard and elsewhere, which can then be analyzed and compared in terms of distance, time, acceleration, and changes in elevation. It can be particularly fun to compare the pathways students take to get to school. I couldn't find a good link for this activity, unfortunately.

31. Determining the acceleration of gravity using a pendulum - This lab always produces consistent results, provided students perform the calculations correctly. Since we use the acceleration of gravity so often in physics, I think it helps students to see that it can be determined with a relatively simple setup. Students will have only tiny pendulums to work with at their desks, but if you plan ahead, you can make a huge one that hangs from the ceiling to show that it works at larger scales, too.

32. Metals and non-metals identification - Depending on what materials you have available, this can be a really great introduction to the periodic table of elements. Chances are your lab already has a good selection of metals, as well as some non-metals like carbon and sulfur. Provide small samples of each material and allow students to rotate to different stations where they attempt to identify the materials using some simple techniques (like magnetism). You can do this entirely visually if you like, or give some obscure facts about each element to help them out.

33. Metal displacement reactions experiment - Students observe whether reactions occur between pure metals and various salt solutions in order to create a simple reactivity series. It's reasonable to test four or five metals in order to introduce the concept, but you'll need to explain that very reactive and unreactive metals are not realistic to test in school due to prohibitive costs and safety concerns. The reactivity series can then be used to discuss why certain metals are chosen for particular uses and why precious metals are so valuable and long-lasting.

34. pH indicator lab - There are many kinds of indicators that can be used to determine pH. Teach students about acids and alkalis, then give them a selection of common household substances like vinegar and soapy water to test with universal indicator. They can then use the results to create their own coloured pH scale in their notebooks and label each substance accordingly. If you want to go a little further, consider making your own indicator solution with purple cabbage!

35. Titration of NaOH with HCl - This classic chemistry experiment involves the neutralization reaction between hydrochloric acid and sodium hydroxide. A small sample of NaOH containing the indicator phenolphthalein is given to each group (this is best done in pairs). Students slowly add acid to the pink alkali solution until it goes clear, at which point it should be neutral. If you have digital pH probes, get students to measure the changes throughout the experiment and plot them on a graph. You can also evaporate the resulting solution to show that salt (NaCl) crystals are formed in the process.

36. Fruit DNA extraction - In this simple lab activity, students use common household ingredients to isolate and observe the DNA found in fruits such as kiwis, bananas, and strawberries. The similarities should help illustrate the fact that DNA is a universal code common to all organisms. Although you can't see the molecular structure of the DNA in this exercise, it's still fun to have a look at your extracted nucleic acids under a microscope.

37. Life cycles investigation - There are a few ways to show students how various plants and animals complete their life cycles. For plants, beans grow quite quickly and the seeds are easy to collect and save. If you have some space and a bit more time, sunflowers are really fun to grow at school, too. Depending on the season, it may be possible to collect some tadpoles from a local pond and observe them as they grow and develop. Insect larvae and caterpillars are fun to watch as well, but a little less exciting until their final metamorphosis. You might even be able to contact a nearby chicken farm and get ahold of some fertilized eggs to incubate. Be sure to provide food and a decent living space for whatever creatures you investigate, of course, and have a plan for what to do with them after you are done observing them.

38. Phenotype investigation - Collect class data for a variety of common genetic traits and compare these to national or global averages. Blood type is ideal, but some students might not know theirs (everyone knows their blood type in Japan so this is an easy one for me!). Other possibilities include eye colour (here's a VERY detailed article on eye colour genetics ), dominant hand, hair colour, or earlobe shape. Avoid things like height, which might single out or embarrass some students. Also, don't do tongue rolling, because despite what you may have heard, the ability to roll your tongue is either mostly or entirely NOT determined by genes .

39. Determining the speed of sound experiment - This one requires some space, and by space, I mean distance. You'll want at least 200m with a clear line of sight for good results. Have a few students position themselves at 100m increments away from a group of observers (the rest of the class). These students will be equipped with some kind of noise-making device that can also serve as a visual cue. We use two blocks of wood clapped together above the head. The observers use a stopwatch to measure the time between when they see the blocks touch and when they hear the sound. This is then used to calculate the speed of sound. If you get really lucky on a stormy day, you can do a variation of this exercise using lightning (from indoors, of course). In that case, your students would be finding the distance of the lightning using an accepted speed of sound.

40. Create a pinhole camera - It's not really an experiment, but it's still a classic physics exercise and for good reason. Nothing more clearly illustrates the function of the eye and retina and the concept of light moving in straight lines than this ancient device. A small cardboard box or similar container forms the basis for the pinhole camera, along with a few other craft materials. Then look at a bright object like a lightbulb or candle to see the inverted image.

41. Hearing or colour sensitivity experiment - For this activity, students will use different videos or apps to determine how well they can differentiate between similar shades of a colour or hear high-pitched sounds. Have the whole class perform the tests and then analyze the results. Students love learning about themselves!

42. Reflection investigations - Using lasers and different types of mirrors, students observe the behaviour of light and construct ray diagrams. This is good practice for drawing clear and detailed diagrams. This can take a while, so it's probably best to split it into two lessons and keep plane and curved mirrors separate.

43. Playing a song with glasses of water - This is a pretty silly activity that I decided to do a few years ago, but there's some solid science behind it. Students can obviously make music on glasses of water without learning anything, so be sure to indicate (and possibly calculate) how and why the pitch changes with volume. Put on a concert at the end of class and get your cameras ready!

44. Water cycle simulation - With just a few simple materials you can easily show many of the processes involved in the water cycle. Get a fish tank and fill it with a small amount of water. Place some sand or a rock on one side to represent mountains. Cover the tank with a clear sheet of glass or plastic so you can still see what's going on. Put a tray of ice above the mountain to represent cold air in the upper atmosphere. Finally, place a heat lamp near the tank to represent the sun (you can also just use the actual sun!). A 'cloud' should form below the ice with lots of condensation which will drip down the mountains and back into the 'ocean'. If you want to speed up the process, try adding warm water to the tank.

45. Weather comparison investigation - Students look up weather information for a number of different cities and record things like temperature, wind speed, humidity, pressure, and so on for a week or two. Then they analyze the data and prepare a report or presentation on the similarities and differences between the chosen locations. They must use their knowledge of air and ocean currents, elevation, latitude, and other factors to explain any observed differences. This works best as a summative assessment comparing where you live to a selection of other cities chosen by the students themselves.

46. Plate tectonics simulation - I've tried several different materials to simulate the movements of tectonic plates, and each has its pros and cons. Slowly pushing crackers over a peanut butter or jam 'mantle' until they collide is pretty fun and shows some fault interactions reasonably well. I also like smashing layers of towels or paper into each other to show how mountains and unusual strata patterns can form. You can also try freezing the top few centimeters of a large container of water (just leave it outside if it's cold enough in winter!). Use a hammer to smash the surface and form a few 'plates'. Then move them across the surface to show plate movements and interactions. You can also use this to illustrate how the continents were once connected as a single land mass.

47. Human sense perception lab - This is one of my personal favourites. Students move around in pairs visiting a variety of stations that put their senses of hearing, touch, taste, sight, and smell to the test. In total students do 13 interactive sense activities that are easy to set up and fun to experience.

48. Plant tropism experiments - Use a fast-growing plant like beans to show how plants grow towards the light (phototropism) and away from gravity (gravitropism). Students can get a bit creative with this one by coming up with modifications to test. Some possibilities include growing a plant sideways or upside down, rotating a plant away from the sun every few days, or covering different parts of a growing shoot with various materials to see how phototropism is controlled.

49. Invertebrate stimuli and response experiments - Unlike mammals, invertebrates such as insects, worms, and snails exhibit mostly predictable responses to specific stimuli. Go outside and collect whatever tiny creatures you can from your local ecosystem. Then bring them back to the lab to test their responses to things like temperature gradients, moisture, light, sound, movement, and so on. Use this opportunity to discuss the ethical treatment of laboratory animals and make it clear that your students must do their best to avoid harming the creatures in their care. Release them where you found them after the experiments are done!

50. Human power experiment - Get your students running up flights of stairs to see how much power a human can generate! I like to kick off this activity by discussing horsepower and its origins as a unit of measurement. Inevitably students want to see how they compare to a horse (and each other), so this always gets competitive. Spoiler alert - your students can't beat a horse! To end the activity, we discuss situations in which a horse can be defeated by a human, focusing on an annual marathon that pits the two species against each other held in the UK. As it turns out, humans perform best when it's hot.

51. Impact crater experiment - This is good messy fun with applied physics! Students drop marbles into trays of flour from different heights and compare the diameter and depth of the impact craters. Use marbles with different masses and calculate the potential energy for each trial. This should equal the kinetic energy on impact. How does the kinetic energy affect crater size and depth? Graph it and find out!

52. Principle of moments lab - Students use a balance beam to solve problems and investigate the principle of moments. This is the idea that when two opposing turning forces act equally on either side of a pivot, they are balanced and no movement occurs. I like this activity because it can be completed in a number of ways, including trial and error, calculation, or a combination of both.

53. Gear ratios experiment - You'll need access to some specific equipment for this one. A bicycle should be easy enough to obtain (or borrow), but I use LEGO technic . Students build simple LEGO cars and switch out different gears to compare the force and speed produced. This takes a while and is definitely more complicated than just demonstrating with a stationary bicycle or similar setup, but it's far more hands-on. This is best for smaller classes or science clubs.

54. Pulley experiment - Here's another activity that requires you to have some materials on hand, although they can be easily purchased from a local hardware store for a reasonable price. Give students an object of known mass and a force meter. Then give them the pulley materials and set them to work on reducing the force needed to lift the mass by as much as possible. If they have already studied the theory behind pulleys, this should be doable, but the reality of setting up a working block and tackle is much more complicated than it seems if you've never done it before.

55. Greenhouse effect simulation - Using sealed jars or other containers, students modify atmospheric conditions to see how temperature is affected. There are many ways to conduct this experiment, so I recommend letting each group of students try something different. Start with a simple control (usually an empty container) and go from there. You can try adding different quantities of water, soil, or ice, or if you can get your hands on it, chunks of dry ice to increase the CO2 concentration.

56. Chemical tests for macromolecules - This is a well-documented set of biochemistry procedures for identifying starch, simple sugars, proteins, and fats in small samples of common foods. You only need a few reagents which should be readily available in most middle or high school science labs. The results involve various colour changes that are pretty fun to observe. Get your students to predict which foods will contain each macromolecule and then test their predictions to see if they are right.

57. Plant nutrient deficiencies investigation - Teach your students how to recognize signs of nutrient deficiencies in plants. These can be seen by examining leaf growth and colour. Then go outside and see if your students can find examples of nutrient-deficient plants around the school. Beware of plants that are naturally red/purple in colour, which could be mistaken for phosphorous deficiencies, and definitely don't try this in the fall for obvious reasons.

58. Digestion simulation - In this activity, students take a sample of food and put it through a series of processes in order to simulate the stages of digestion. This doesn't sound that fun, but it involves a lot of smashing, squishing, and messy fun. Crush the food inside a plastic bag, add some water and hydrochloric acid, filter it through a pair of socks or stocking 'intestines', and then compact the leftover chunks to make 'poop' (kids love it). Combine this activity with the chemical tests from experiment 56 above for a more in-depth analysis. I like using cornflakes or a similar cereal as the carbs are pretty easy to break down and there is enough iron for you to actually extract and see.

59. Digestive system dissection - If your students aren't too squeamish, consider dissecting something to view its digestive system. Whole fish are easy to obtain here in Japan so that's what I use. Rather than opting for a class set, if you splurge for a big one, you can cut open the stomach and examine the contents. I did this several times with carp in college and there was always lots to see. If you happen to know a hunter, you might be able to get something much larger. Enjoy!

60. Protease enzyme experiment - Some fruits, such as pineapples, naturally contain protein-digesting enzymes. If you attempt to make gelatin with a sufficient quantity of these fruits, it won't solidify. Try a bunch of different fruits and see which ones contain enzymes and which don't. Make sure you use fresh fruits as canned varieties can be unreliable. Then discuss enzyme activity and its importance in digestive processes.

61. Cell respiration experiment - Use germinating beans or yeast to indirectly measure the rate of cell respiration at different temperatures. You can accomplish this by placing these organisms inside a sealed system called a respirometer and measuring their CO2 production. It's a little complicated to set up for students, but you can prepare some of the materials ahead of time yourself. This experiment encourages accurate measurement techniques and can be used on invertebrates as well!

62. Magnetic field investigation - Put a magnet on a piece of paper and sprinkle with iron filings. Then draw the resulting magnetic field lines. Try different magnet shapes, or add multiple magnets in different arrangements to see how the magnetic field changes. If you have clear sheets of plexiglass or even just a blank laminated sheet you can put the magnets underneath and make cleanup MUCH easier.

63. Make a compass activity - Float a magnetized needle on water and watch it point north. Everyone has probably done this one at some point, but for younger students, this is still a tried and true way to observe the Earth's magnetic field. Apparently, you can also just suspend a bar magnet on a string and accomplish the same thing, but I've never tried that. Might be worth a go!

64. Fruit and vegetable battery experiment - Use a lemon or potato to generate electricity and power a simple device like a fan or light bulb. That's the basic version, anyway. You can make it more of an experiment by comparing how pH affects the voltage produced or by adjusting the distance between the electrodes. Obviously, you can also compare different fruits and vegetables to see which works the best. Some of them might surprise you (try a pumpkin!).

65. Series and parallel circuits investigation - Build different kinds of circuits and compare the voltage and current at different points. You'll need quite a few materials for a full class activity, including batteries, components, and a lot of wire, so consider doing this as part of a station activity if supplies are limited. You can also get kits that simplify and streamline the building process, but I like making students do it the hard way!

66. Electrical conductivity experiment - Compare the resistance of various materials using a multimeter. It's as simple as it sounds and generates really good data. The hardest part is finding similar materials for a fair test, as your wires need to be the same length and diameter if you are comparing different metals. One version of this activity involves using graphite from pencil drawings to compare conductivity. Simply draw two large dots on paper and connect them with a line. Then measure by placing your multimeter on the dots. Try making long or short lines, waves, or other shapes. Increase the thickness of your lines to see if that makes a difference.

67. Total internal reflection experiment - Shine a laser into a semi-circular transparent block at different angles until it reflects back rather than refracting through. You can use a small clear container or fish tank as well. Get students to use a protractor to find the critical angle, which can be calculated and compared for that substance as well. There are better ways to observe total internal reflection, including streaming water and the use of fiber optics, but those work better as demos.

68. Audio format sound quality experiment - Convert lossless quality music files to MP3s at different bit rates and see if your students can hear the differences in quality. You can do this with a free music editor such as Audacity . It's harder than you think, even with good headphones. If you have no idea what I'm talking about, read the linked article about file formats and audio quality. Compare WAV files to 320 kbps VBR MP3s and 192 kbps CBR MP3s. Let your students choose their favourite songs if you like, or give them some music education by choosing yours!

69. Wi-fi signal strength experiment - See how different variables affect the signal strength of wi-fi signals, such as the distance, number of connected devices, or physical obstructions. Download a free signal strength app that measures in dBm to compare signals and collect data. Since this is a logarithmic scale you can take the opportunity to teach students about that, too. This is a super practical experiment that students find quite relevant to their needs.

70. Sheep/pig brain dissection - Another dissection, this time with a medium-sized brain. In order to get the most out of this lab, it's best to frontload a lot of the terminology and be sure students are familiar with the main brain regions and their functions. I like to get kids to follow along with a video dissection, pausing as needed, or just use a document camera to guide them through it yourself if you're confident to do so. One word of wisdom - don't freeze your brains prior to dissection. I do this with hearts and thought it would be fine, but nope! Brains turn to mush when you thaw them out.

71. Properties of bone experiment - Cook and soak bones in acid to remove the substances that give them strength. Chicken bones are the easiest to obtain, especially if you plan to have enough for a full class (there might be a wing night or two in your future!). You can combine this lab with a microscope investigation of bone tissue, or look at cross-sections of bones from avian and non-avian species (images are fine).

72. Antagonistic muscle groups activity - Construct a model of an antagonistic muscle group (the biceps/triceps arm pair is almost always used) and observe how the bones and muscles work during flexion and contraction. There are many different materials that can be used to make this work. It can be as simple as popsicle sticks and elastic bands, or more complicated models using wood or PVC to represent the bones and stretch cords or balloons for the muscles.

73. Observing body tissues microscope lab - Students look at a variety of human tissues under the microscope and attempt to identify them. It's not that hard to create mounts of different plant tissues, but animal tissues are a lot less practical. For these, I like to get a good set of prepared slides and have students do an ID quiz by rotating around the room. I'll usually give them a list of possible tissue types to choose from, but I don't always teach them what to look for ahead of time. The reasoning behind their choices is usually very good and worth writing down.

74. Microscope / biological drawings lab - In this lab, we revisit some properties of cells from earlier courses and refresh the students' memories on proper microscope use. In the process I have them create very detailed microscope drawings of protists - usually paramecium at 400x. The goal is to draw for accuracy and scale. I also need to regularly emphasize that students draw what they see, not what they expect to see.

75. Organs diagram activity - Students are given cutouts of human organs and have to place them in their correct positions on a blank torso. You can do this at the beginning or end of a topic (or both!), but either way, it's pretty hilarious to observe at times. After students are fairly confident with their choices, I have them label and annotate their diagrams explaining what each organ does. Finally, we look at the actual diagram and make corrections where necessary (I usually use a student exemplar from someone who knows what they're doing!). I've also done a whole class version of this exercise where I draw a life-sized torso on the whiteboard and have students take turns placing organs on it. There's a lot of communication from the 'audience' and it's always entertaining.

75. Dichotomous key activity - Students create a dichotomous key to differentiate and identify a selection of everyday objects. Sure, you could do this with images of actual species, in which case I would stick with a group of closely related organisms (turtles, sharks, cats, bears, etc.), however, I find that this is much more engaging when done with objects that have nothing to do with biology. Save yourself time and money by using whatever you have on hand, like candies, school supplies, or weird and random objects from your 'junk' drawer!

76. Flame test lab - Always a student favourite, this lab involves burning small quantities of metal salts to produce coloured flames. These can be used to identify specific metals. It is also the basis for the colours seen in fireworks. While that connection is easy to make, it's much harder for students to understand why each metal produces a different colour, but this is actually a good opportunity to introduce electron configurations. Let your students use their phones for this lab and they'll enjoy taking lots of cool photos and videos.

77. Properties of ionic and covalent compounds experiment - There are lots of ways to do this (and lots of compounds to test), but the simplest one I know of is to compare salt (sodium chloride), sugar (sucrose), and paraffin wax. Students can examine a number of properties, including melting point and conductivity, to determine the typical features of ionic and covalent substances. A much more interesting version of this experiment involves giving students a bunch of unknown substances and asking them to determine whether they are ionic or covalent. This is most easily accomplished by testing for conductivity, but let them figure that out for themselves!

78. Properties of metals lab - Students test a bunch of common metals to investigate their properties. This can include both a qualitative (describe the colour and other physical features) and quantitative analysis (measuring the conductivity, density, and so on). I find it best if you can get equally sized samples of each metal, whether that be cubes, wires, or strips. I usually have students fill out a table of all the properties. I also include a few rare metals (like gold, platinum, iridium, etc.) that they have to research and add to the table themselves).

79. Electroplating experiment - Students use a zinc solution and electricity to coat a copper plate with a thin layer of zinc. I make this a seasonal activity by drawing holiday-themed designs on the copper using a permanent marker. When removed, it creates a nice contrast between the dull grey zinc and shiny orange copper metals. Heat it lightly in a Bunsen burner and you'll create brass instead. Then punch a hole in the top and you've got a unique ornament for your Christmas tree.

80. Preventing rust experiment - Take a selection of iron nails and coat them with different protective substances before placing them in water. Leave them in there for a few days to see how much they rust. The goal is to learn about the factors that contribute to corrosion and to see if we can prevent it with readily available materials. You can also do a follow-up experiment where you use things like acid to remove the layer of rust.

81. Newton's 3rd law skateboard experiment - There are lots of versions of this, but I like to get kids up and moving a bit using rollerblades or skateboards if possible (safety first!). Get a student to sit on the skateboard and then toss a medicine ball. Measure how far they threw the ball and how far they rolled, and then repeat this with different masses of medicine balls (and students!). Do lots of trials to smooth out inconsistent data. If you don't have skateboards you can always just use balloon-powered rockets or cars to show the same concepts.

82. Hooke's law elastic spring constant experiment - With nothing more than a few small weights and an elastic band, you can investigate Hooke's law. This is so simple and quick that I would recommend doing it more than once with either different elastics or springs . As the name implies, springs produce better data, but you might not have enough for a full class, and once they're stretched out, that's pretty much the end of them.

83. Center of gravity experiment - Students try to find an accurate way of locating the center of gravity for irregularly shaped objects. I don't tell them how to do it at first to see if anyone can come up with a decent method. We might even test a few ideas if they seem reasonable, but otherwise, we'll go to the prescribed lab to complete the activity. All you need is a thick paper cut into irregular shapes. I use pieces of cardboard or old greeting cards.

84. Engineering challenges activity - Create and test towers and bridges using craft materials or building sets, then test them for strength and efficiency. Normally I do this at the end of our unit on forces and structures, but this year we did it twice - once at the beginning and then again after they had learned some more about construction and engineering. The results were greatly improved! My resources for this particular experiment are freely available here , by the way.

85. Types of mixtures lab - This is another great example of an experiment that makes use of what you have, saving you time and hopefully a shopping trip. Students mix household solids and liquids to explore different types of homogeneous and heterogeneous mixtures. Use small quantities as this lab can generate a lot of waste that needs to be cleaned up. You can also illustrate the Tyndall effect by shining a flashlight through your mixtures to see if they scatter the light.

86. Dialysis or potato osmosis experiment - Use dialysis tubing to illustrate the concept of osmosis, typically with sugar, salt, or starch solutions of varying concentrations. Unfortunately, I rarely have dialysis tubing on hand, so we do the potato version with saltwater instead. I've been keeping our data for many years, however, so we compare and combine the data to arrive at much better results. My big breakthrough with this method has been to use cookie cutters when preparing the potato samples. It makes the sizes and surface areas much more consistent, although you still have to weigh each sample. 24 hours is a perfect amount of time to leave your samples in solution.

87. Molecular gastronomy spherification lab - Students make bubble tea using fruit juice. This is a fairly challenging experiment, but the result is often worth the effort (plus, you can eat it). Molecular gastronomy has a lot more to explore and honestly I wish I knew more about it. I've always wanted to try an activity to have students create and taste unusual flavour combinations based on similar chemical compounds, but I've never gotten around to it.

88. Chromatography crime lab - Separate the pigments in marker ink using various solvents in order to solve a 'crime'. You can go full CSI on this one if you're inspired to do so, and I think kids appreciate it. The experiment itself is not that thrilling, so you really have to play up the forensics angle and focus on the practical aspects of the technique.

89. Infection simulation - Give each student a solution that represents their body fluids. One student is 'infected' with a different solution. Students mingle around sharing fluids for a few rounds before testing the liquids to see who else is now infected. The cups containing the infected solution turn bright pink when phenolphthalein indicator is added. This is one of my favourite activities for exploring immunity, vaccination, and viruses. It also lends itself very well to discussions on STIs.

90. Graveyard survivorship and life expectancy investigation - Visit a local graveyard and collect as much data as you can. Then analyze it over the next couple of lessons. This is very location dependent, but luckily you can access similar records online using sites like Find A Grave . I still think going to the actual site where people are buried is much more meaningful, but it works either way. Use the results to create survivorship curves, compare life expectancy over time, and look for specific birth and death events. Try doing this as an interdisciplinary activity with social studies!

91. Electron flow student simulation - Kids act out an electrical circuit by pretending to be electrons. It sounds stupid, but it works beautifully and even older students usually come around once they try it. Increase the voltage by having students move faster. Add components and batteries using chairs or levels to show gaining and losing energy. Add switches to stop and start the flow of students. Then create a series or parallel circuit and get students to adjust their movements accordingly. Surprisingly I couldn't find a decent online version of this, so I guess I need to upload mine soon!

92. Fuse wire experiment - Use fuse wires of variable thickness to explore the relationship between current and resistance. You'll need a low-voltage power supply and the wires themselves, as well as other standard electrical circuit materials. This has the potential to be slightly dangerous, so be sure to prepare students adequately beforehand and make safety requirements clear.

93. Water quality investigation - There are many aspects of water that can be tested in schools, including hardness, pH, and the presence of nitrates. Purchase water quality testing kits to save yourself a ton of effort. I send each kid home with a small container and tell them to get some water. Most kids will bring their tap water, but some get creative and scoop a sample out of a puddle, pond, stream, or toilet (ew...). Label everything accordingly and then start analyzing those samples! I really love showing the film Erin Brockovich in combination with this activity as it's directly related and based on a true story.

94. Acid rain plant germination and growth experiment - Various concentrations of acidified water are used on germinating seeds and healthy plants to observe the effects on their growth and general health. You can use vinegar as the experiment here suggests, but I make a more realistic batch of 'acid rain' by combining nitric and sulfuric acids in order to get a pH below 5. We then dilute this solution as necessary to use on our plants. I like to use radishes since they grow so quickly and require very little space/depth. You can grow them right in the classroom with a few trays or planters.

95. Natural selection simulation - Students act as predators to capture prey using a variety of utensils. Both predator and prey populations change with each 'generation', but only the strongest survive! I really like this activity for introducing or reviewing the concept of natural selection, and it pairs well with the board game Evolution .

96. Hominid migration mapping activity - This website is awful, but the activity is great. Students use hominid fossil data to plot locations on a map and then suggest migration routes our ancestors might have taken. There is one typo in the data but I always forget to write down which one it is. Don't worry, your students will find it! When finished you can refer them to this updated interactive which helps explain human migration patterns.

97. Kepler's laws investigation - This is really a collection of experiments to explore the laws of planetary motion outlined by Johannes Kepler about 400 years ago. Students will be drawing and performing calculations related to ellipses and learning about centripetal force. There's a decent amount of geometry and other maths involved, so you might want to coordinate with the math department if that's something that interests you.

98. Lenses investigation - Using a series of lasers and lenses, students refract light and produce images on a screen to find focal lengths. This can be difficult without the proper equipment so I think it's worth investing in a couple of decent optics sets for your lab. Treat them well and they should last practically forever.

99. Eye dissection - Cow eyes are typically used for this investigation of eye structure and function. It's simple enough, but I haven't done it in years since it's hard to get the materials where I live. If you want to avoid the mess, there are many virtual options or videos you can use instead.

100. Doppler effect experiment - A simple smartphone app is used to explore the way motion affects sound frequencies. The experiment itself is pretty easy to do, but it's important to then link these concepts back to light and the expanding universe, which is responsible for the red-shift observed with very distant objects.

101. Night sky investigation - Another set of app investigations that use star-gazing software on your phone or tablet to explore the locations and movements of celestial objects. The good thing about these apps is that you can complete them in broad daylight, but I still think it's worth organizing a star-gazing event at night with telescopes so that students can view actual planets and moons. If you aren't confident running this yourself (I'm not), ask a physics teacher or contact your local astronomy club/observatory.

102. DIY Spectrometer experiment - Got a pile of useless CDs? Use them to create your own spectrometer to observe the spectral lines from different light sources. There are far more complicated designs available online if you are a tinkerer, but I find that this one works well enough for our purposes. There are some apps that will analyze a photo of spectral lines and suggest what elements might be present, but there isn't a single one that I would really recommend at this time. Explore what's available on your device as apps are constantly changing.

103. Molecular modeling activity - I'll take any excuse to get out the modeling kits. For this activity, students practice making various organic functional groups. I sometimes give each group equal components and see what kinds of different isomers they can come up with. It's easy to get caught up with complicated naming procedures in organic chemistry so I find that this hands-on activity helps to put some of the theory in perspective without being too demanding. If you want to challenge your students on a rainy afternoon (or whenever) give them something really big to make, like a phospholipid, or a section of DNA.

104. Esters investigation - Making esters by combining carboxylic acids with alcohols is relatively straightforward, if you have access to the necessary reactants. Students get to smell a bunch of things and relate this to compounds found naturally in foods and those artificially added to perfumes and other products. This lab makes use of concentrated sulfuric acid, which only you should handle for safety reasons.

105. Polymer slime activity - Making slime is fun for all ages, but you might wonder why I do it with grade 10 as it's more of an elementary school type of activity. Although younger students love to make and play with slime, they can't really appreciate the chemistry behind it, so that's why I toss this in at the end of a tough organic chemistry unit. You don't have to make the usual borax / PVA slime, but I find that it is simple and flexible enough to illustrate all of the concepts I want to hit. We also use this as a jumping-off point to discuss the use of plastics and other polymers as well as their effects on the environment.

106. Identifying plastics lab - Not all plastics are created equal in terms of their suitability for recycling. In this experiment, students will use the density of various plastic samples to identify them. We often watch a documentary associated with this experiment, such as Plastic Problem or Plastic Wars , both from PBS.

107. PCR and gel electrophoresis experiment - If your school has a PCR and electrophoresis machine, you're good to go and can begin examining samples of DNA without much effort, but if you don't, you'll need to connect with another organization that does. In the past, I've taken students to local universities in order to make use of their equipment, which they are usually happy to share for educational purposes. Sometimes they even prepare the lesson for us!

108. Flower anatomy investigation - If you plan to teach this unit in the warmer months you'll have access to all kinds of flowers you can dissect and examine. If you want to leave them on the plants you can just take photos I guess, but you'll miss out on exploring what's inside. Large flowers such as lilies are among the best and most straightforward examples of flower anatomy, but be sure to have a look at other flower types, including composites like sunflowers to see if your students can still identify all of the structures. Don't just look at flower structure, however. Make sure you discuss the functions of each part, and more importantly, why each species has evolved in a particular way. This is a good chance to talk about pollination as well.

109. Radioactive decay simulation - This is a statistics activity using dice to determine radioactive decay events. The experiment involves graphing, half-life calculations, and discussions on nuclear waste, so it's a well-rounded activity for any unit on radiation.
