Human Body Project Ideas

Rate of cognitive decline in different elevations.

Oxygen partial pressure decreases with altitude, challenging blood oxygenation which may affect brain function. If you’ve ever felt some altitude sickness, then this is exactly what’s happening. This is because the atmospheric pressure decreases at higher elevations, leading to a decrease in the partial pressures of the gasses in the air, including oxygen. And of course, oxygen is needed for us to function. What is the effect on brain health/ cognition in sudden increased elevation: say, climbing Mount Everest? Does chronic exposure to high elevations increase the likelihood of dementia? In this project, a meta-analysis of published works examining the effects of altitude on cognition would be conducted.

Idea by mentor Alyssa

Building a Blood Vessel

Use online graphics to illustrate how a blood vessel forms. Blood vessels are structures that carry blood and are responsible for transporting nutrients and oxygen throughout the body. There are three main types of blood vessels: arteries, veins, and capillaries. For this project, complete a literature search to understand what is known about blood vessel growth. Then, utilize this information to generate a graphic with no words to demonstrate how the vasculature (network of blood vessels) forms. The goal of this project is to explain science without using text and therefore make it more available to a larger community.

Idea by mentor Natalie

Examining the bacterial profile of various households

As of late, bacterial microbiomes have been a huge and interesting topic in the field of bacteriology as they play an important role in human health. Bacterial microbiomes are communities of bacteria that live on or outside organisms. They’re found in various parts of the human body, and help us to digest food and regulate our immune system. In this project, you will seek to understand how skin microbiomes can differ between different  individuals of different households. This project will require making different bacterial media that can be made at home selecting for various microorganisms. If you’re new to preparing bacterial media, check out this resource here!

Idea by mentor Hamilton

Regulation of Circadian Clocks

Sleep is known to be governed by two distinct processes: a circadian clock that aligns sleep and wakefulness to the solar day and the sleep homeostat that encodes for sleep debt as a compensatory mechanism against sleep loss. You’ve most likely heard about circadian rhythm and our body’s internal clock, and circadian regulation of sleep is a fundamental process that allows animals to anticipate sleepiness or wakefulness consistently every day. These mechanisms can be regulated in multiple ways: at the gene, protein, gene, and clock neuronal level. In this project, we will focus on 1) how to efficiently digest primary and review articles to compile and condense information, 2) investigate how circadian clocks are regulated at these different genetic levels, and 3) try to effectively summarize the information we've gathered. We can present this information in a variety of ways, and what the final product looks like is up to you.

Idea by mentor Oscar

The Biology of Aging

Aging is the number one risk factor for a variety of diseases including cancer, neurodegenerative disease, and loss of hearing/sight. We are only now beginning to truly understand the process of aging and have even started to uncover ways that we could stop, or potentially reverse, the effects of aging. What are the hallmarks/signs of aging? How do researchers study 'aging'? How does human lifespan and aging compare to the rest of the animal kingdom? Is it possible to stop or reverse the effects of aging? What advancements are being made related to this? We could explore these questions or brainstorm others you might have about the biology of aging.

Idea by mentor Emily

Animals, Plants, and Nature Project Ideas

How genetically engineered mosquitoes are reducing rates of vector-borne diseases such as zika.

Many countries are already releasing millions of genetically engineered mosquitoes into the wild every week. These mosquitoes have been modified to reduce their ability to transmit disease-causing pathogens like dengue fever, Zika, and malaria, and are sent into the wild to mate with disease-carrying mosquitoes. However, this is still controversial as some people are concerned about the unintended consequences on the environment. What could be the potential pros and cons for this? The project will mainly focus on doing meta analysis of articles and watching informative videos to understand how/why genetically engineered mosquitoes can be used to reduce rates of different diseases. Students will have the chance to use critical thinking and do in-depth research on genetic engineering techniques, how scientists determine breeding rates and number of insects released, and epidemiology of different bloodborne diseases.

Idea by mentor Vanessa

Efficacy of Marine Protected Areas

Marine protected areas (MPAs) are areas of ocean or coastal waters that are set aside for the conservation and sustainable use of marine resources. These areas are established by governments, NGOs, or other organizations, and they can take different forms, from fully protected "no-take" zones to areas with regulated fishing or other activities. Marine protected areas have the potential to guide sustainable resource management and protect biodiversity, but have a host of reasons for why they are not currently effective. Explore reasons for why MPAs may not be effective. Then develop a framework for mapping, modeling, and implementing an effective Marine Protected Area.

Bioinspiration: Do animals hold the answers?

Can the toxins produced by frogs help us fight antibiotic resistant bacteria strains? How can understanding how lizards and newts regrow their limbs help us improve wound treatment? Why do tilapia skins help with burns? Discover the role of animals in the development of modern medicine as well as its potential. Are there any ethical concerns with these developments and findings? If so, what are they and do they matter? Share your findings in a research proposal, article, or presentation.

Idea by mentor Cheyenne

How Climate Change Can Affect Future Distributions of Rare Species

Climate change, such as global warming and longer drought, can threaten the existence of some of the rarest plants on earth. It is important to understand how future suitable habitats will change for these rare species so that we can target our conservation efforts in specific areas. In this project, you will identify a rare species that you like (it can be animals, plants, or fungi!), and gather the data online on its current occurrences. Then you will learn how to perform species distribution modeling to map its current and future suitable habitat areas. To get you started on learning species distribution modeling, check out this Youtube resource here. The changes in the amount or location of future suitable habitats can significantly affect the destiny of a rare species. By doing this project, you will not only learn skills in data analyses but also become the best ambassador for this rare species that you love.

A Reef’s Best Frenemies

Coral reefs are in global decline. A primary cause of this is "coral bleaching" which results in the white reefs we often see in the news. Coral bleaching is actually the breakdown in the partnership between the coral animal and tiny, symbiotic algae that live within its cells. Corals and algae have a variety of thermal tolerances which are likely decided by genetic and environmental factors. However, despite how important this relationship is, it's currently very poorly understood. This project would review existing literature on the symbiotic partnernship and try to identify factors that predict bleaching and thermal resilience.

Diseases and Treatments Project Ideas

The understanding of a new and upcoming treatment: immunotherapy.

Immunotherapies have been growing in the past few years as alternative treatments for many types of cancer. These treatments work by boosting the patient's immune system to fight the disease, however it is not always effective. There are many types of immunotherapies with various nuances, but they all work to attack specific cells that are causing the disease. For this project, pick one of a few types of immunotherapy and deeply understand the mechanism of action and what is the current effectiveness against the cancer it treats.

Idea by mentor Hannah

Exploring The Cancer Genome Atlas data 

There has been an explosion of publicly available data for cancer. The Cancer Genome Atlas was a research program with the purpose of creating a comprehensive catalog of genomic and molecular information about different types of cancer, with the aim of improving our understanding of the disease and developing new treatments. The dataset has been used to identify new cancer subtypes, develop diagnostic tests, and discover potential targets for new cancer therapies. Explore the implications and impact of The Cancer Genome Atlas data, and why it’s become so important.

Idea by mentor Hersh

Systematic Review and Meta-Analysis of Physiological Benefits of Fasting-induced Autophagy

Autophagy, meaning "self-eating", is a cellular process where damaged or unwanted components are disposed. Autophagy has been linked to various diseased pathologies, including cancer and heart disease. Fasting or specific dietary lifestyles may induce levels of autophagy in the human body. In this project, we will perform and systematic review and meta-analysis of fasting or diet-induced autophagy and its benefits on the body. You will gain skills in 1) searching and reviewing primary literature, 2) computational skills for performing data analysis (R language), and 3) writing your scientific findings.

Idea by mentor Jose 

The Amyloid Hypothesis: Sifting through the controversy

For many years, scientists have thought that amyloid beta was the protein responsible for a patient developing Alzheimer's Disease symptoms. This "Amyloid Hypothesis" is now being questioned in light of current clinical data. Recently, drugs have been developed that reduce amyloid beta in patients. Surprisingly, the drugs worked in reducing amyloid beta, but it did not result in the slowing of disease pathology. Does this mean that the amyloid hypothesis is incorrect? Is amyloid beta less important in the progression of disease then what we once thought? This research project aims to explore the issues with the amyloid hypothesis and to assess where we stand in our understanding of amyloid beta's contribution to Alzheimer’s.

Idea by mentor Patrick

How do vaccines work?

During the COVID pandemic, vaccines have been all over the news! But how do they actually work? What’s the science behind them? Through this project, you will explore how vaccines work and the history of science behind vaccine development. While the final product of the projectwill be up to you, the ultimate goal of this project is for you to be a true public health advocate for vaccines and to be able to communicate why vaccines are so important in a way that the general public can understand.

Idea by mentor Helen

Sleep Disruption Profiles in Various Mouse Models of Alzheimer’s

Alzheimer's disease (AD) has been studied for decades but we are no closer to understanding the mechanisms of the disease. Because of the vast number of researchers studying AD, there are numerous models used to study the disease. All these models have different sleep profiles, phenotypes, disease onsets, sex differences etc. Therefore, in this project we will compile a document based on extensive literature review about the various models there are. We will focus on sleep profiles in these animals with an emphasis on male and female differences. This information is valuable because it is important to know which model is best to use to answer your scientific questions and there is a lot of criticism (by other scientists) that can be brought on by the model chosen so you need to be able to justify your choice. This project will also introduce you to the world of AD research and some of the gaps in knowledge in the field.

Idea by mentor Shenee

Rethinking The Treatment Of Neurodegenerative Diseases

Neurodegenerative diseases affect millions of people worldwide. They are conditions that affect the nervous system, particularly the brain and spinal cord, and examples include Alzheimer’s and Parkinson’s. While billions of dollars have been spent trying to find treatments for the disease, very few drugs and therapies have had a meaningful impact on slowing down disease progression. This is often because by the time someone is diagnosed with a disease, it has progressed too far for a treatment to have a substantial effect. Some recent approaches to treatment have turned to looking for early indications of the disease (termed "biomarkers") that can occur before the onset of symptoms. By diagnosing disease and beginning treatment before symptoms arise, these treatments could have a more profound effect in slowing down the progression of disease. Students could review the recent progress being made on identifying biomarkers for neurodegenerative diseases, and either write a paper or even record a podcast on their findings!

Idea by mentor David

Genetics Project Ideas

Height and genetics: nature or nurture.

How much do your genes determine your height? How much do nutrition and environmental factors play a role? What gene variants are implicated in height differences and what is the role of epigenetics? Epigenetics is the study of heritable changes in gene expression or cellular phenotype that occur without changes to the underlying DNA sequence. These changes can be influenced by diet and lifestyle. We will access and analyze an open dataset on twins to estimate the correlation between monozygotic twins (who have the exact same DNA) and height. You will learn to use R to open a dataset, analyze data with statistical methods such the student’s t-test, and display your data as graphs and charts. Finally, you will learn how to make a research presentation on height and genetics, describe the research methods, and present the data in a compelling and thorough way.

Idea by mentor Adeoluwa

The World of Personalized Medicine

Similar to our fingerprints, our genetic code is also unique to each individual person. Our genetic code is what determines our hair color, height, eye color, skin tone...just about everything! For those that develop diseases such as cancer, their genetic code found inside the malignant cells that comprise a tumor may also be unique to them or to certain groups of people with similar mutations (the drivers of disease). So why is it that we treat each person the same way even though the genetic drivers of that disease may be disparate? The world of Personalized Medicine is new and exciting and looks to circumvent this problem. Personalized Medicine (also known as precision medicine) uses the genetic code of a patients disease to guide treatment options that prove to be highly efficacious. Together, lets write a review on a disease of your choice that could benefit from Personalized Medicine based on current literature and research.

General Biology Project Ideas

Teach a biology concept two ways: to your fellow students and to the general public.

One of the best ways to learn is to teach. Choose a biological concept that interests you and prepare a lesson and or demo on it. The format should be a video recording of yourself teaching (a la Khan Academy or a Zoom class), but the other details are up to you. Consider incorporating a demonstration (e.g. how can you use items from your kitchen to illustrate properties of mixtures?) or animation (e.g. to illustrate molecular motion). Also consider how you will check that your students understand the concept(s) and/or skill(s) you have taught them. Prepare and record two versions of your lesson: one intended for your peers and one for the general public. How will the versions differ to reflect these different audiences? You will learn what it's like to teach, gain a much greater understanding of your chosen concept(s)/skill(s), and learn how to communicate science to different audiences.

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
• Medium: Items that you might not already have but are easy to get your hands on
• Advanced: These require specialized or more expensive supplies to complete

Science fair projects give you the opportunity to experience science and biology through hands-on activities . In order to ensure that you have a great biology project, it is important that you first understand biology and the scientific method . Simply put, biology is the study of life. Life is all around us which means that there are enormous possibilities when considering a biology science project. We use the scientific method as a means of studying science and biology. Scientific inquiry starts with an observation followed by the formulation of a question about what has been observed. Then comes designing a scientific experiment to answer the question posed.

So where do you get ideas for biology science fair projects? The answer is from almost anywhere. The key is to start with a question that you would like to find an answer to and use the scientific method  to help you answer it. When choosing a science fair project topic , make sure that you select a topic that you are interested in. Then narrow this topic down to a specific question.

Below you will find science fair project ideas primarily related to biology. Remember that these samples are meant to give direction and ideas. It is important that you do the work yourself and not just copy the material. Also, be sure that you know all of the rules and regulations for your particular science fair before you begin your project.

Plants are important to life as we know it. They provide everything from food, clothing, and shelter to medicine and fuel. Plant projects are popular because plants are abundant, inexpensive, and relatively easy to study during experimentation. These experiments allow you to learn about plant processes and environmental factors that impact plant life.

Experiments are a standard part of biology courses, whether they are part of a controlled laboratory class, science fair, or individual student projects. Explore a few fascinating high school biology experiments; and discover ideas for simple and easy biology experiments to incorporate into your curriculum.

Examples of Biology Experiments for High School

Whether you are looking for a science fair project or need to create a project for a class assignment, there are numerous biology projects for teens.

• Planting Spring Bulbs: An Easy-to-Follow Guide for Beginners
• 7 Senior Bio Examples to Help You Craft Your Own

Frog Dissection

Dissecting a frog is a quintessential part of high school biology. If possible, try to get both female and male specimens for your class so students can see the eggs and compare the insides to the male frog.

Flower Dissection

High schoolers can get a bit squirmy about frog dissection. Have a flower dissection instead. The teens can find and label the female and male parts of the flower. It can be fun for high schoolers to check out flower intricacies under a microscope.

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.

Phototropism

It can be enlightening to show kids how phototropism affects plants. They can set up an experiment by using different materials to affect light. They can see how affecting the light affects the growth of the plant.

Water From Common Sources

Water is everywhere. Unfortunately, water contains numerous elements too. A great experiment is collecting water samples from various sources and viewing them under a microscope. Students can then compare their results and attempt to postulate why a given water source would present more organisms than another would.

Yeast Experiment

Another experiment involves taking a piece of bread to monitor the molds that grow over a period of two weeks.

Taste Perception

Everyone has their own taste. Literally! Some people like sour things while others like sweet. Find out if everyone perceives taste the same way and has the same threshold for taste by doing an in-class experiment.

Disinfectant Effectiveness

Ever wonder how effective hand sanitizer is at killing bacteria? Test it! Grow bacteria in a Petri dish along with paper soaked in peroxide, white vinegar, rubbing alcohol, etc. Find out how each one of them works to inhibit bacteria growth.

Pea Plant Genetics

Students can recreate Mendel's genetic pea plant experiments . By growing pea plants and comparing their phenotypes, students can determine each parent plant's genotype.

Examining Fingerprints

Fingerprints are pretty amazing features on the human body. Not only can you use them to open your phone, but each one is unique . Put your fingerprint on paper and examine the different aspects of the lines and arches on your fingers. Compare fingerprints among everyone in class.

Comparing Animal and Plant Cells

To better understand animal and plant cells, students can compare cells from their cheeks to cells from an onion. Just stain the cells with iodine or another dye to better see the cell structures under a microscope.

Creating a DNA model is a great way to help students understand the structure and function of DNA in genetics. Students can use candy, string, and toothpicks to develop a fairly realistic model of the double helix structure.

Water Bottle Germs

Many people refill their water bottles in high school. But do they add germs or bacteria to the bottle? Is refilling a disposable water bottle safe? Have students take swabs of the water bottles they use and look for bacteria around the lid or on the bottle.

Testing Hair

Teens use a lot of hair products. But do they truly work? Have teens in your class take a few samples of their hair. See what happens to the hair when common hair products are added.

Water Cycle

Understanding the water cycle isn't hard. But teens can look at it firsthand by creating a water cycle experiment. Just have them fill a baggie with water and tape it to a window. They will watch evaporation, condensation, and precipitation in action.

Closed Ecosystem Bottle

It can be hard for students to imagine something having its own ecosystem. However, you can use a plastic bottle to create a closed ecosystem.

Field Survey Biology Experiment

This experiment is great because it is cheap, easy, and you can do it in a variety of areas around your school or send students home with it. The goal is to observe the surrounding area over time and monitor the samples that you collect.

Materials You'll Need

For this experiment, you need to grab:

• Jar or baggies to collect samples
• Stakes and string or cones help mark an area
• Paper or journals for taking notes
• Slides, slide covers, and a microscope

Observation Instructions

Take note that you will observe your area for several months, so choose an area that is easy to re-mark or where you can leave the markings up, so you return to the same designated area each time.

• Have students choose one spot to observe. The spot should be no more than two to three feet square.
• Do you see evidence of animals? (Look for prints, scat or guano, fur, owl pellets, etc.)
• What plant life do you see? (Look for moss, lichen, weeds, and other plants).
• What fungus do you see? (Look for mushrooms and other fungal growth).
• What insects do you see? (Encourage students to look specifically for relationships here - such as connecting mosquitos with water or bees with flowers or a hive).

Sampling and Classroom Instructions

Bring the research back into the classroom by following these instructions.

• Guide students to make connections and note relationships in their marked area. Have them inventory the area and draw a crude map of where everything is.
• If possible, have students use tweezers and gently take samples of soil, fungus, moss, plant life, insects, etc.
• pH value of soil or water
• Microorganisms in water
• Plant cells under a microscope
• Comparative structure of flowers you find
• Require students to record everything in their own journal or interactive notebook.

Teacher tip: Set up stations in the classroom for viewing, dissecting, drawing, testing pH, etc. This will allow students some choice in how they proceed with examining their specimens.

Testing for Bacteria

Have students see where the most bacteria are lurking. This experiment is great if you want a lab that has guaranteed results. There is always some kind of bacteria lurking somewhere, just waiting to grow in a student's Petri dish.

These are the materials you are going to need to have on hand.

• Prepared Petri dishes, three per student
• Sterile swabs
• Painter's tape
• Scotch tape
• Permanent Marker
• Graph paper

Material notes : You can also purchase sterile Petri dishes and agar separately; however, it is much more likely students will contaminate the plate before they swab.

Preparing Your Petri Dishes

Prepping your Petri dishes is an essential part of the experiment.

• Before opening any materials, have students identify three places (but in one physical location such as at home or at school) that they are going to swab for bacteria. Encourage them to hypothesize about which place they think will grow the most bacteria.
• Using the Petri dish, trace three circles on the graph paper and cut it out.
• In pencil, draw a line to denote the 'top' of the circle. It doesn't matter where you draw the line, but you will need something to show you how your Petri dish is oriented so you can be sure you're tracking the same colony each time you observe.
• On the back of the graph paper circle, note the location where you will take the swab, as well as the date you are taking the swabs. Do this for all three Petri dishes you have.

Collecting Samples

Have students bring their unopened sterile swabs and closed Petri dishes to the site. Carefully, they should:

• Set the Petri dish down on a flat surface.
• Unwrap the swab.
• Swipe the swab across the area they suspect has bacteria.
• Lift the lid, gently wipe the used swab across the agar, and close the lid, carefully but quickly.

Hint: Sometimes, it's helpful to tape the Petri dish shut so that the Petri dish doesn't accidentally lose its lid.

Evaluating Results

Now that you've swabbed the areas, it's all about the results.

• Have students draw Petri-dish-sized circles in their lab books or on separate graph paper. Draw one week's worth of Petri dishes for each dish the student has.
• As the colonies start to grow, have students draw the size in their notebooks, making daily observations. If they cannot observe daily, have them observe on the same day(s) over a month.
• They should also be recording the color and other notable features of their bacteria colonies in their lab books.
• At the end, the students should write a conclusion of their study.

The Effect of Light on Growth

In this lab, students investigate how light affects plant growth. Students may use any plants, but cress will grow more quickly, so your students can get results faster.

Gather up your materials.

• Styrofoam cup or bowl
• Potting soil

Instructions

With your materials at the ready, it's time to start your experiment.

• On Day 1 - plant seeds in the soil in the cups.
• Label the cups according to the light you're going to use. You can compare sunlight vs. complete darkness, or you can compare several types of light.
• On each day after the initial day, take a picture of each cup and try to measure the growth, if any.
• For your lab entries, measure the sprouts, and note color and shape characteristics.

Planaria Regeneration

In this lab, students watch the rate at which planaria regenerates and test whether how you cut the planaria makes a difference as to how they grow back.

To conduct this experiment, you want to grab.

• 9 planarias
• 3 small plastic Petri dishes
• 1 large plastic Petri dish
• 1 plastic pipet
• 1 magnifying glass
• 1 plastic coverslip
• Spring water
• Paper towels
• Ice pack(optional)

Setup Instructions

Getting the setup right is half the battle when it comes to creating fun and interesting biology experiments for high schoolers.

• Start by numbering the three small Petri dishes to ensure nothing gets confused later.
• Using the pipet, move a planarian into the large Petri dish.
• At this point, you may want to try to set the Petri dish on an ice pack for a few minutes. This isn't totally necessary, but it will slow the planarian down to make it easier to cut.
• Right behind the head
• Right in the middle
• Right towards the tail
• Use the pipet to gently transfer each segment to a new Petri dish (with spring water).
• Repeat the steps with all remaining worm segments.
• Every day, observe the planaria. Regeneration will be considered 'complete' when the photoreceptors (the black dots that look like eyes on the planarian's head) appear.

Scientific Method and High School Biology Experiments

Much of high school biology is focused on instilling the elements of science in students. The scientific method is one of these main focuses. The method prompts participants in science to be investigators and to come up with a guess about what will happen in a given experiment, called a hypothesis. The point of the experiment is then to either prove the hypothesis correct through the experiment or prove it incorrect. This prompts teens to get involved in the scientific method while teaching other scientific skills, such as:

• The ability to make a rational estimate based on present factors and knowledge
• Close detail and monitoring skills
• The possibility of being wrong and how to move past that if it turns out to be the case
• Quick thinking skills

As much fun as biology experiments can be, there is an educational component spearheading the experiment.

Fun and Interesting High School Biology Experiments

For teens, high school biology can be fun. Finding the right experiment can help biology pop off the page and become more than just another required course of study. Who knows? Perhaps your student will even be prompted to enter a science fair or a career rooted in science?

Fun Biology Projects Using Independent & Dependent Variables

When conducting experiments, you need to properly note variables to make accurate conclusions. Variables are the parts of the experiment that change, or variate. Independent variables are not affected by the other variables; they are independent of the others. Dependent variables do change according to the other variables; therefore, they are dependent on those variables.

Seed Size and Germination

In this experiment, you'll determine the percentage of large and small seeds that germinate. The seed size is the independent variable, because nothing in the experiment affects the size of the seeds. The number of seeds that germinate is the dependent variable. This variable is affected by seed size and other independent variables in the experiment, such as water, light and soil composition. Plant a few large seeds, such as pumpkin seeds. Plant the same number of small seeds, such as tomatoes. Water the seeds equally, and place them where they get equal sunlight so that the only difference between the two is the size of the seeds. Document the percentage of large and small seeds that germinate.

More For You

Small physics experiments based on buoyancy, boat flotation experiments for 5th-graders, activities to teach science process skills to 2nd grade, how to test algae growth for a science fair project, how to measure how much the sun shines on solar panels, gender and eye-blinking rates.

Select subjects, half female and half male. For this experiment, the independent variable is gender, because nothing else changes. The rate of eye blinking is the dependent variable, because it differs according to the sex of the subjects. Sit and observe the subjects as they do ordinary tasks, such as writing, reading or talking, and count the number of times the subjects blink in one minute. Analyze the data to determine if one sex blinks more frequently than the other and which one blinks the most.

Air Temperature and Ant Hill Activity

Air temperature is the independent variable and ant activity is the dependent variable in this ant hill experiment. Locate an ant hill. Observe the ants coming and goings and record your findings. Place a heat source -- like a space heater or a bright incandescent light bulb -- directed to warm the air outside the entrance of the ant hill. Record the activity of the ants again. Did they appear to move faster or slower when warmer? Remove the heat source and record the ants' activity again. Did they appear to be slower when colder? Or were there no noticeable changes? Draw conclusions about how heat effected the ants' movements.

Lights and Plant Growth

Light is the independent variable, and the dependent variable is plant growth in this classroom experiment. Start seedlings, or purchase some that are already a few inches high. Place some of the plants outdoors or in a well-lit window. Place the others across the room from the window. Alternatively, use an artificial light source and completely control the amount of light each group of plants receives. Record how quickly each plant grows by measuring its growth rate with a ruler. Note where each plant is when you measure it -- outside, inside in a well-lit window or away from direct sunlight -- and conclude which amount of sunlight helps your plants grow the fastest.

High School Biology Experiment Ideas

Science Projects on Dish Detergents

High school level biology covers all aspects of biology, including animals, plant life and humans. That should mean it’s easy to come up with a science fair project or a classroom research project, but the amount of topics sometimes makes it even harder. When you first start researching, you’ll find thousands of ideas and it’s difficult to decide which one is best for your situation. Provided that you know what you want to do and what your teacher or judges are looking for, it’s easy to come up with a great biology experiment.

Effects on Plants

Test the effects of different substances on plants. Place plants from the same source in pots of the same size, then use different types of materials. You can test different types of potting soil against regular dirt or use the same type of potting soil and test other substances. Water the plants with different types of bottled water and tap water from your home and other homes or add a small amount of vinegar and other liquids to see how the plants react to those substances. Observe the effects of the different substances on the plants and measure how quickly each plant grows in comparison to the others.

Water Bottles

Test the amount of germs and toxins found when you refill a water bottle. Start by taking a sample swab from the outside lip of the bottle and looking at the water under a microscope for any bacteria or impurities. Then drink from the bottle as you otherwise would and test the bottle each time you refill it with extra water. Student athletes can even use the same plastic water bottles they carry with them to practice every day. Each time, you'll want to swab the inside lip of the bottle and look at the swab under a microscope. Identify any bacteria or toxins by looking at the examples found in your textbook.

Public Germs

You might be surprised when you check different public areas for germs. Take swabs at public bathrooms, in your classroom, on the door handles at stores and even books at the public library. Look at the swabs under a microscope and see what types of germs you find. Then offer a comparison of the germs and explain your findings. Discuss which germs are harmful and what levels of germs you found.

Do a biology experiment focusing on how the hair reacts to different types of products. Test shampoos, conditioners, hair gels, hair sprays and other products. Look for residue left behind by the product, but take a few sample hairs before you begin. Check the consistency and health of the sample hairs under a microscope and compare those results against hairs after using the products. Observe any changes you notice in the look or feel of your hair, as well. Then look for signs that the hair has become more damaged or healthier since you used the product. You’ll need to narrow it down to just a few products, but if you have more time, use one product for several days before switching to another.

Top 10 Biology Experiments You Don't Want to Miss

January 14, 2019 4 min read biology experiments science activities

A few years back we shared a series about how to teach the different areas of science at home, which you can find here:

• Teaching Biology at Home
• Teaching Earth Science at Home
• Teaching Astronomy at Home
• Teaching Chemistry at Home
• Teaching Physics at Home

The posts in the series have remained some of our most popular posts and so we thought we would help you all out by sharing our favorite experiments for each discipline!

We are going to start this series out with biology - here's how you can teach biology at home .

And without further ado, here are our top 10 biology experiments!

Top 10 Biology Experiments

1. Dissect a Flower  

Many of the typical spring blooms, such as lilies, tulips, and daffodils, have clearly seen elements, which makes them excellent specimens for your students to study the structure of a flower.

One of the best ways to do this is through a flower dissection! These step-by-step directions for a flower dissection will help you examine the structure of a flower.

2. Raise a Butterfly

Butterflies go through an amazing life-cycle. A butterfly lays an egg, from which a caterpillar emerges. Then, the caterpillar eats and grows, eventually forming a chrysalis. And several weeks later a butterfly emerges!

There is nothing like watching this process in action! And these instructions on how to grow a butterfly will help you observe this life cycle in action.

3. Extract DNA 

DNA is the stuff that tells our cells what to do and how to look. It resides in the nucleus of a cell, so as you can imagine it is quite tiny. In fact, you normally need a very powerful microscope to see DNA for yourself.

That is unless you extract it and force it to join up together into one giant mass of DNA. And that is exactly what you do with this Banana DNA Extraction experiment .

4. Make a Seed Board 

Plants start their lives out as seeds and there is a huge variety of seeds, just like there is a huge variety of plants.  

These four steps for making a seed board will help your students appreciate the differences and similarities between seeds.

5. Dissect an Owl Pellet 

This one often grosses people out, but dissecting an owl pellet is a great way to learn about bones and animal diet.

Don't worry, owl pellets are not from the backside of an owl. Owls swallow their prey whole, so a few hours after the meal, they will regurgitate the indigestible parts in the form of a pellet.

These four steps for dissecting an owl pellet will help you get the most of this fascinating but slightly suspect dissection.

6. Look at Fingerprints

Our body is covered with an amazing organ know as skin. It's the largest organ of the integumentary system. The  skin on our fingers, toes, palms of your hands, and soles of your feet is folded into tiny ridges. These ridges form swirling patterns, that help our hands and feet grip things.

These directions for examining your fingerprints will help your students understand just how amazing our skin is!

7. Grow an Herb Cutting

Roots are the structure of a plant that anchors into the ground and helps the provide the plant with the nutrients it needs to grow.

These directions for growing an herb cutting will help your students see how roots grow and get a chance to examine roots up close without getting dirty! 

8. Make a Habitat Diorama 

Our planet is covered with different types of habitats. Habitats are the place that is normal for the life and growth of a certain animal or a plant. In other words, it's the area where an animal or plant resides.

These directions for how to make a habitat diorama will help your students learn about the different plants and animals in an area in a hands-on way.

9. Eat a Cell Model

The cell is the basic unit of life, but it's so small that we can't see the cell's structure with our naked eyes. Enter the cell model.

You can make a jello cell, a cake cell, or a cell calzone to eat, but whatever cell you choose to snack on, these edible models will help your students visualize this basic building block of life.

10. Create a Fall Leaf  (or Signs of Spring)  Journal

When you study biology, it's a good idea to learn about the nature surrounding you. 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.

Wrapping it Up

There are loads more options for biology experiments out there that we love - in fact, we probably could have done a post with 100 experiments! But these are the ten we don't want you to miss.  If you want more biology experiments, check out our Biology Pinterest board .

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.

Meet students who spent their summer pursuing sustainability research

Through programs offered by the Stanford Doerr School of Sustainability, undergraduate students from Stanford and institutions across the U.S. worked on projects that tackled pressing environmental challenges and advanced fundamental knowledge about our planet. Here’s an inside look at their experiences.

This year, more than 70 undergraduate students engaged in summer research to develop new skills and deepen their understanding of Earth, climate, and society. Through five programs part of the Stanford Doerr School of Sustainability , undergraduates explored sustainability-related issues in disciplines ranging from energy and civil engineering to oceans and social sciences.

The five programs include Mentoring Undergraduates in Interdisciplinary Research (MUIR), organized by the Woods Institute for the Environment ; Summer Undergraduate Program on Energy Research (SUPER), organized by the Precourt Institute for Energy ; Sustainability, Engineering and Science - Undergraduate Research (SESUR); Hopkins Internships - Summer Undergraduate Research Funds (HI-SURF); and Sustainability Undergraduate Research in Geoscience and Engineering Program (SURGE).

The SURGE program is funded by the National Science Foundation and welcomes students from other U.S. institutions, especially those from underrepresented backgrounds doing research for the first time. The other programs receive funding from the Vice Provost for Undergraduate Education (VPUE).

Across all the programs, undergraduates contributed directly to research projects under the guidance of Stanford scholars. They also participated in shared group activities such as research seminars and graduate school workshops.

The large cohort allowed participants to learn from each other in addition to a variety of mentors. Building this community of support, in contrast with the sometimes isolating nature of individual research, was one of the main goals of bringing the five programs together last year.

Whether pursuing a scientific interest, trying out new tools, or discerning a potential career path, students used this summer to grow both academically and personally. Many hope to expand on the work they started, while others are moving forward with newfound clarity on their discipline. As they wrapped up their projects, three undergraduates shared insights about their research, personal growth, and how they made the most of the experience.

Evelyn Pung, ’27, SESUR participant

For Evelyn Pung, the motivation to research the link between environmental quality and human health was a personal one.

She grew up 10 minutes away from the ocean in Long Beach, California, but she rarely took trips to the beach. “The pollution at our beaches had gotten so bad, my parents didn’t want me to go, out of health concerns,” she said.

This summer through the SESUR program, Pung got involved in a project in the lab of civil and environmental engineering Professor Nick Ouellette . With her mentor, PhD student Sophie Bodek , she studied the movement of tiny plastic particles in bodies of water. Understanding how these pollutants travel through water in different environments can inform efforts to limit their spread.

Pung said that the freedom to actively control the experiment, combined with supportive mentorship from Bodek, made the research especially fulfilling.

“This whole experience has been a gratifying learning opportunity,” she said.

Trent La Sage, ’25, SURGE participant

Trent La Sage, an undergraduate student at the University of Florida, conducted research that brings together physics, Earth science, and materials science.

His project tackled a common problem in materials science: Insights about certain materials are not easily accessible to researchers. While findings about materials at ambient conditions can be uploaded to a public database for other scientists to reference, no such platform exists for materials at extreme conditions.

To address this, La Sage and other scholars worked on a program that uses computer vision and large language models like Chat GPT to pull data from published research papers, which can then be applied to work on future computational models.

The opportunity to collaborate on a large team was a highlight for La Sage, who appreciated the variety of viewpoints. He brought his own distinct perspectives to the group – both in discipline, as the only physics and astrophysics major, and in experience, having started his undergraduate education after several years in the workforce.

“It was very helpful to have people from other backgrounds. And we’ve been able to get a lot of things done that I wouldn’t have been able to get done myself,” he said.

Juan Martín Cevallos López, ’26, HI-SURF participant

After recurring moments of awe and discovery in his oceans-related classes at Stanford, Juan Martín Cevallos López, who prefers to be referenced by his first and middle name, discovered a passion for ocean science. He knew he wanted to get involved in research at the Stanford Doerr School of Sustainability’s Hopkins Marine Station in Pacific Grove and applied to the HI-SURF program.

Juan Martín contributed to three different projects – studying the impacts of ocean acidification on a particular species of seaweed, the development of bat star larvae in various temperatures, and the role of crustose coralline, a key component of coral reefs, in temperate environments such as Monterey Bay.

Throughout his research, Juan Martín was thrilled to be able to combine his knowledge of oceanography with other scholars’ expertise in marine biology and ecology, and he is eager to continue studying the ocean.

“I’m excited to see where it takes me, because it can literally take you anywhere,” he said.
