16 Super Cool (And Simple) 1st Grade Science Projects To Do At Home

Categories Activities & Ideas

Science can be a lot of fun for first graders (especially if they’re taking part in experiments that go whizz, pop and bang).

To solidify their scientific learning, and make sure they’ve fully understood the concepts, you can set them the task of completing a science project with their parents.

To avoid a free-for-all, and to take the pressure of the parents, you can provide your class with a selection of projects to choose from.

Below, we’ve listed 16 of the coolest (but simple) 1st grade science projects kids can do at home with their parents.

Get those goggles on and we’ll get to it.

1. Density Tower

A density tower is a simple experiment for first graders to try at home.

Children will need different liquids like honey, dish soap, water, vegetable oil, and rubbing alcohol; a clear, tall glass or plastic container.

The great thing about this experiment is that most of these items will be readily available at home.

Method: Carefully pour each liquid into the container, one at a time.

Start with the densest liquid, like honey, and end with the least dense, like rubbing alcohol.

Students should notice that the liquids form layers.

This experiment helps children understand the concept of density and how some liquids are denser than others.

2. Growing Crystals

Although you can buy kits to grow your own crystals, doing it from scratch is much better fun (and it’s better for the student’s learning).

To grow crystals, they will need salt or sugar, hot water, a jar, a string, and a pencil.

Method: Dissolve as much salt or sugar as you can in hot water until no more will dissolve.

Hang the string into the jar so that it’s not touching the sides or bottom, using the pencil to hold it in place.

After a few days, crystals will begin to grow on the string.

This teaches kids about the process of crystallization and how solids can dissolve in liquids and then reappear when conditions are right.

3. Shadow Tracking

First graders will need a sunny day for this science project. They will also need a toy or object, chalk, and access to a sidewalk.

Method: Place the toy on the pavement and use chalk to trace its shadow in the morning, noon, and afternoon. Observe how the shadow changes.

This helps kids learn about the movement of the Earth in relation to the sun and how it affects shadows.

4. Magnetic Exploration

For this project, children will need a magnet and a collection of small items from around the house.

Method: Children can test which items are magnetic and which are not. They can separate the items into two piles: magnetic and non-magnetic.

This introduces the idea of magnetism and helps children identify which materials are attracted to magnets.

5. Dancing Raisins

This experiment is super fun and only requires clear soda (like Sprite or 7-Up), a clear glass, and raisins.

Method: Fill the glass with soda and drop in a few raisins. Watch as the raisins “dance” up and down in the glass.

The carbonation in the soda attaches to the raisins, making them float to the top. Once the bubbles pop, the raisins sink again, illustrating the concept of buoyancy.

6. Celery and Food Coloring

This experiment will make first graders laugh while also teaching them about plant life.

They’ll need clear glasses, water, food coloring, and celery stalks with leaves. Method: Fill the glasses with water and some drops of different food coloring shades to each glass. Place a celery stalk into each glass. Over a day or two, observe the celery, especially its leaves.

This experiment illustrates capillary action and how plants absorb water and nutrients from the soil.

7. Balloon And Static Electricity

First graders are probably already familiar with the static generated by balloons but this experiment helps them understand a little more.

They will need a balloon and small pieces of paper or lightweight fabric.

Method: Inflate the balloon and tie it off. Rub the balloon on your hair or a piece of wool. Move the balloon close to the pieces of paper or fabric and watch them jump towards the balloon.

8. Homemade Volcano

Kids of all ages LOVE a volcano experiment.

For this one, the first graders will need a small bottle, baking soda, vinegar, dish soap (for a foamy eruption), and food coloring (optional for colored lava).

Method: Place the bottle on a tray or in a container to catch the overflow. Fill the bottle a quarter full with baking soda. Add a few drops of dish soap and food coloring if desired. Pour vinegar into the bottle to start the eruption.

This classic experiment demonstrates a basic acid-base reaction.

9. Ice Melting Race

This fun experiment helps children understand the different properties of substances and how they can affect the state of matter.

They will need ice cubes, plates, and various materials like salt, sugar, and sand.

Method: Place an ice cube on several plates. Sprinkle different materials on each ice cube: salt on one, sugar on another, sand on the next, and leave one as a control with nothing added. Observe which ice cube melts the fastest.

10. DIY Sundial

The DIY sundial experiment is nice and easy and doesn’t require much to do.

All that’s needed is a straight stick (a pencil will do the job), a sunny day, and a piece of paper or a paper plate. Method: Stick the stick through the paper or plate. Every hour, mark the end of the stick’s shadow with a stone or by drawing on the paper. Label each hour as you go.

This project demonstrates how the position of the sun in the sky changes over time and can be used to tell time.

11. Floating Eggs

This is another super easy science project for first graders – and you don’t need many items, so parents will be a fan.

This requires fresh eggs (this part is important), salt, two clear glasses, and water.

Method: Fill both glasses halfway with water. Add a lot of salt to one glass and stir until most of it dissolves. Carefully place an egg in each glass and observe.

This experiment teaches about buoyancy and density. The saltwater is denser than freshwater, which can make the egg float.

12. Homemade Compass

For this science project, first graders and parents will need a needle, a small cork or foam piece, a magnet, and a bowl of water.

Method: Stroke the needle repeatedly in one direction with the magnet. Insert the magnetized needle into the cork or foam and place it on the water in the bowl. The needle should align with the Earth’s magnetic north.

This introduces the idea of Earth’s magnetism and magnetic fields – and most kids find this one pretty awesome.

13. Coffee Filter Chromatography

This project demonstrates how different colors can be combined to create other colors and introduces the concept of chromatography. It allows first graders to be a little creative.

To do this task, they will need non-permanent markers, coffee filters, and cups of water.

Method: Draw a dot or a line with the marker in the center of the coffee filter. Fold the filter so the center is at the bottom and dip it into a cup of water (ensuring the dot/line doesn’t touch the water). Watch as the water rises and separates the ink colors.

14. Pepper And Soap Trick

This is a pretty cool science experiment which will amaze little ones.

It requires ground pepper, dish soap, and a bowl of water. Method: Sprinkle some pepper on the surface of the water. Then, dip a fingertip into dish soap and touch the water’s surface. The pepper will rapidly move to the sides of the bowl.

This illustrates the concept of surface tension in liquids.

15. Germination Station

Demonstrating germination isn’t an instant results science project, but it’s a useful one to try with first graders – they can return to inspect the experiment every day for the first signs of sprouting.

To do this at home, they will need bean seeds, paper towels, a clear plastic bag, and water.

Method: Moisten the paper towel with water and place a few bean seeds on it. Fold the paper towel gently around the seeds and place it in the plastic bag. Seal the bag and fix it to a window with strong tape. In a few days, observe the seeds sprouting.

16. Solid, Liquid, Gas With Chocolate

This tasty science experiment will show first graders solid, liquid and gas – the three primary states of matter.

Kids and their parents will need chocolate pieces, a pan, and a freezer.

Method: Show the solid chocolate piece. Melt it in a pan to show its liquid form. As it cools, steam or vapor may be seen, representing the gas state. Finally, you can place the melted chocolate in the freezer to revert it to its solid state.

These science projects can easily be done by first graders at home with their parents.

Most of these experiments don’t require many items, and kids will have a lot of fun with them.

33 Engaging & Inspiring 1st Grade Science Projects

There are a lot of 1st grade science projects that can help children draw conclusions and make connections to the world around them. In first grade science, children learn about topics within life, physical, and earth sciences. That means there are a lot of different types of science experiments to choose from when looking for an engaging (or easy) project for your class or at home.

Table of Contents

What science topics do 1st graders learn, the best 1st grade science experiments, what are some easy science projects, check out these additional 1st grade resources.

Through the life sciences, first graders learn about the characteristics that differentiate living and nonliving things. They learn about animals and how they adapt to and interact with their surroundings. 

Children at this age also learn about the seasons, weather patterns, and the water cycle through the earth sciences, along with the phases of the moon. 

First graders are also introduced to the basic concepts of motion and forces where they explore how objects move, and they manipulate variables so they can compare cause and effect . Students this age learn how to ask a question that can be answered through investigation and observation. So a good science experiment that supports these topics starts with a testable question that children will be able to answer at the conclusion of the investigation.

In partnership with Teach Simple , whose marketplace is full of educational materials created by actual teachers (plus 50% of all revenues go to them), I’ve gathered 33 great kid-friendly science projects that your first grader will enjoy in the classroom or to pass the time by at home. Have a look! 

The projects in the list below address the topics I mentioned above that 1st graders learn in school. Allow your child to take the time to manipulate variables and make observations and discuss them with you during the experiments so they can also learn how to draw conclusions. 

• Make A Rainbow From Children’s Museum

First graders love to learn about rainbows. This experiment shows how white light is a combination of all the colors of the rainbow. When you shine the flashlight on the glass of water, the light waves are refracted, or bent, causing the light to break into its various colors. 

Supplies you’ll need:

• Clear glass
• Darkened room

If you’re looking for a bit more to hit this concept home, try out Teach Simple’s Colors Science, Literacy and Math Activity by KP Classroom, which provides companion activities to support this experiment.

Using paper chain models, your students will practice their fine motor skills by creating a paper chain showing the energy flow from the sun to the organisms.

Be the lucky charm of the day with a magical science reaction!

What if you could add a little spark to vinegar and baking soda? Your students will predict what will happen when you mix yellow vinegar and blue baking soda. 

This is a great way to see if they can apply their art knowledge of primary colors coming together to make a secondary color!

Explore the wonder of clouds with our little eyes!

Take your students outdoors using a cloud viewer to discuss the movement of clouds and the different types of clouds. 

Your students can sketch drawings and write about how clouds change through observations. Follow up with a class discussion of their observations and what cloud changes mean.

Create shade for man’s best friend!

With various scrap materials, your class will work in teams to design a shade structure to protect their dog figurine from getting too hot from the sun using some parameters.

Students create a plan, improve their ideas, and test their creations in class before going outdoors to see them in action.

Getting Started with Science Experiments

Embarking on the journey of science experiments is an exciting way for first graders to discover the world around them. They’ll learn to ask questions, observe outcomes, and understand the cause and effect relationship through hands-on activities.

Understanding the Scientific Method

The scientific method provides a systematic approach for young learners to investigate the natural world. It typically entails five steps: asking a question , making a hypothesis , conducting an experiment , observing and recording results , and drawing conclusions . Incorporating the variables of the experiment, which are factors that can be changed, such as the amount of light or water, is essential for students to understand their impact on the experiment’s outcome.

Safety Tips and Preparation

Safety is paramount when conducting science experiments. Educators and parents should prepare by reviewing safety guidelines such as wearing protective gear and identifying any possible hazards. It’s crucial to explain to first graders the importance of not tasting or touching chemicals and to always have an adult present during experiments to maintain a safe learning environment.

The Role of Supervision

Supervision ensures that children are guided through the scientific method and adhere to safety protocols. An adult supervisor serves as a facilitator of learning, helping to keep the experiment focused and educational. They ensure that the young scientists make observations and record their findings accurately, fostering a safe and supportive environment for inquiry.

Materials and Equipment

Before beginning an experiment, it’s important to gather all required materials and equipment . For simple first grade experiments, items often include common household objects such as measuring cups, water, paper, and crayons. For specific science activities, such as weather experiments , materials might include items like balloons or straws to demonstrate principles like air pressure. Preparing all materials in advance ensures the experiment can be conducted smoothly.

Exploring the Basics of Matter

Introducing first graders to the fundamental properties of matter is a pivotal part of their science education. This exploration helps them understand how various materials interact with each other and with their environment.

States of Matter: Solid, Liquid, and Gas

Matter exists in three primary states: solid, liquid, and gas. A solid has a fixed shape and volume, such as a block of wood. Liquids have a set volume but change shape based on the container they are in, like water in a glass. Gases , such as air, have neither a fixed shape nor volume, and they will expand to fill any available space.

• Solid : Fixed shape and volume.
• Liquid : Set volume, shape shifts to container.
• Gas : No fixed shape or volume, fills space.

Density and Buoyancy

Density is a property that describes how much mass is contained within a given volume. It is a key factor that determines whether an object will sink or float in a liquid. An object denser than the liquid will sink, whereas one with lower density will float. For example, a rock will sink in water because it is denser than the water, while a piece of wood floats due to its lower density.

• Sink : Object denser than the liquid.
• Float : Object less dense than the liquid.

Chemical Reactions in Everyday Life

A chemical reaction involves the transformation of substances into one or more different substances. These reactions are observable in everyday life and can be a fascinating discovery for first graders. Mixing baking soda and vinegar demonstrates a simple reaction where these two substances react to form gas bubbles, an example of a solid and liquid reacting to produce a gas.

• Chemical reaction : Transformation leading to new substances.
• Example: Baking soda + Vinegar = Gas bubbles.

Nature and Biology Projects

Introducing young learners to the complexities of the natural world through hands-on experiments is an effective method for engaging their curiosity. These projects explore the life cycles of plants and animals, the structure of ecosystems, and the fascinating behaviors of insects.

Plant Life: From Seed to Flower

First grade students can witness the miracle of germination by planting seeds in clear plastic cups to observe root and shoot development. Through this activity, they learn the basics of photosynthesis and the life cycle of plants as they care for their seedlings and watch them grow into blooming flowers.

Exploring the Animal Kingdom

Children are often inherently interested in animals, making this an exciting area for study. Exploratory projects may include constructing animal habitat dioramas or observing wildlife to understand the concept of camouflage and other survival strategies. Encountering the diversity of the animal kingdom helps students appreciate the multitude of life forms that share the planet.

The Fascinating World of Insects

The insect world offers a microcosm of learning opportunities. Simple activities like catching and examining insects, then documenting their characteristics, can illustrate concepts such as insect life cycles or the importance of insects in the ecosystem. Projects can range from studying the behavior of ants to creating butterfly gardens that facilitate the study of these pollinators.

Understanding Ecosystems and Habitats

In this subsection, students could construct model ecosystems in bottles or examine different types of habitats within their local area. The objective here is to understand the interconnectedness of ecosystems, and how plants and animals coexist and rely on each other for survival. Comprehensive projects could explore the impact of environmental changes on a habitat and its inhabitants.

Experimenting with Physical Science

First graders can begin to understand the world around them through engaging and tangible experiments. From the power of magnetism to the basics of motion, energy, and electricity, physical science in the first grade makes crucial concepts accessible and exciting.

The Magic of Magnetism

They observe the invisible force of magnetism as objects are attracted or repelled. Simple activities involving magnets —like creating a magnet-powered fish game—introduce young learners to concepts such as magnetic poles and magnetic fields.

Fun with Physics: Motion and Energy

Experiments focused on physics can make learning about motion and energy a hands-on experience. A classic balloon rocket experiment showcases the third law of motion , demonstrating that every action has an equal and opposite reaction, captivating first graders with the fast-moving results.

The Wonders of Electricity and Circuits

When children experiment with static electricity , they visually grasp the idea of electrical charges through simple but striking experiments, like making hair stand on end with a balloon. They also learn the basics of creating an electric circuit using a battery , wires, and a small light bulb, laying the foundation for understanding how electricity flows and energizes devices in their daily lives.

Delving into Earth and Space Science

First grade students can embark on an exciting journey through Earth and Space Science, beginning with the foundation of geology and moving to the complexities of weather cycles and the basics of astronomy. Engaging science activities are designed to introduce students to these foundational concepts.

Rocks and Geology: Uncovering Earth’s Layers

Students will discover the fascinating world of rocks and geology by examining different types of rocks. They will learn to classify rocks and may even have the chance to break open geodes , revealing the crystals inside. Through simple experiments, they can understand how soil layers represent various geological periods.

The Water Cycle and Weather Patterns

The Water Cycle is a key element of Earth Science and is crucial in explaining weather conditions . First graders can recreate the water cycle in a classroom experiment by simulating evaporation, condensation, and precipitation. Basic concepts of weather patterns are explored through observations and predictions, reinforcing their understanding of the world around them.

Astronomy for Beginners: Sun, Moon, and Stars

Embarking on a celestial adventure, Astronomy for Beginners introduces them to our Sun , the Moon , and the stars . Through activities like charting the moon phases and observing the stars, young students begin to grasp the vastness of our solar system and the fundamental principles that govern it.

Principles of Light and Sound

First grade science experiments provide an excellent foundation for understanding how light and sound work. These experiments can demonstrate the basic principles that govern these natural phenomena, such as how light can mix to create new colors, and how sound travels through various materials.

Optics and Color Blending

When it comes to light , young learners discover that it behaves in fascinating ways. An experiment might involve a prism which splits white light into its constituent colors, a vibrant demonstration of color mixing . Children can learn that by combining different colors of light, such as red, green, and blue, one can create a whole spectrum of other colors, including the ones they see every day.

Sound Waves and Vibrations

Sound, unlike light, requires a medium like air, water, or solid materials to travel. First-grade experiments often explore sound waves and how they stem from vibrations. Striking a tuning fork or plucking a guitar string can illustrate how these vibrations create sound waves that one can hear. It’s not just instruments that can do this; everyday items like stretched rubber bands or hollow tubes can bring sound vibrations to life, elucidating that sound travels through various materials in waveforms that can be both seen and felt.

Chemistry Experiments for Young Learners

Chemistry is an exciting branch of science that can captivate young minds through interactive and tangible experiments. First grade students are introduced to the foundational concepts of chemistry such as acids, bases, and the creation of simple polymers like slime.

Acids, Bases, and pH Levels

Understanding the basics of acids and bases is essential in the study of chemistry. A simple cabbage pH indicator experiment is a safe and visually engaging way for students to learn about pH levels. Using red cabbage juice, they can test various household liquids to determine if they are acidic, basic, or neutral. This experiment provides a colorful display of the pH spectrum and conveys the chemical properties of common substances.

Mixing Solutions and Observing Reactions

Young learners can observe chemical reactions by mixing solutions . A fun introduction to this concept is the “baking soda and vinegar” reaction. Students will witness the release of carbon dioxide gas when these two substances mix, resulting in fizzy bubbles. This immediate reaction helps them to understand the interaction between an acid (vinegar) and a base (baking soda) and the concept of gas production in chemical reactions.

Creating Polymers and Slime

Polymers are a class of materials made up of long chains of molecules. An engaging way to introduce students to polymers is by creating slime . By mixing a borax solution with glue and a bit of water, students can see the chemical process of polymerization. As they stir the ingredients together, the mixture becomes slime, which is a type of polymer. This tactile experiment not only demystifies a complex concept but also provides a safe and fun learning experience.

Fun with Environmental Science

First grade science experiments offer a fantastic opportunity to introduce young students to environmental science in a hands-on way. They can learn how simple actions can contribute positively to their environment and understand the basics behind renewable energy sources.

Recycling and Conservation Projects

Students can undertake recycling and conservation projects to grasp the importance of resource preservation. A simple project like creating a classroom compost bin explains how organic waste decomposes and reduces landfill waste. They can monitor changes over time, see firsthand the reduction in waste, and learn about the benefits of compost for growing plants. To further drive home the concept of conservation, students can participate in a recycling workshop where they sort recyclable materials and learn which items can be given a new life.

Renewable Energy: Solar and Wind Power

First graders are often captivated by the power of the elements. Teachers can channel this fascination into learning about renewable energy . Crafting a mini solar oven from simple materials like a pizza box, aluminum foil, and plastic wrap provides a practical demonstration of the sun’s energy. Children can observe the power of solar energy as they melt chocolate or marshmallows for a s’mores activity. Additionally, they can explore wind power by constructing basic windmills from paper cups and straws. This hands-on approach solidifies their understanding that energy can be harnessed from natural sources around them, and sparks curiosity about how the wind can be used as a power source.

45 Easy Science Experiments for Kids

Hello, STEM! These simple DIY activities can be done at home or in school.

We've been independently researching and testing products for over 120 years. If you buy through our links, we may earn a commission. Learn more about our review process.

Imagine blowing the biggest bubbles imaginable — or even making bubbles within bubbles. Or sending vessels — rockets, tea bags, airplanes — soaring through the sky for impossible distances. Now imagine making things explode, or change colors, or reveal hidden messages with just a few simple mixtures.

First off, it's good to start them off with the scientific method. Give them a journal to record their observations, questions, hypotheses, experiments, results and conclusions. As always, safety counts: wear goggles and coats or aprons if need be (sometimes kids get a kick out of how scientific the protective gear makes them look), and always make sure that the kids are supervised when doing them. (Warning: Some of these are messy!)

These experiments are mostly designed for preschoolers through elementary schoolers — with a couple that are either demonstrations or better for older kids — but if you have a younger one, you can check out these 1-year-old learning activities , toddler learning activities and preschool/kindergarten learning activities , some of which also cover STEM subjects.

Floating Fish

Here's another one that deals with solubility and density.

• Draw the outline of a fish on the bottom of a glass plate or tray in dry-erase marker. Retrace your drawing to make sure all the lines are connected. Let dry for a minute or two.
• Fill the measuring cup with tap water. Place the pour spout just inside the corner of the dish and add water very slowly until it just covers the bottom. Be careful not to pour water directly onto your drawing or make splashes near it. The water will move toward your drawing, eventually surrounding it. Observe what happens. If the water splashes or it doesn’t work on your first try, empty the dish, erase the drawing with a paper towel, dry off the dish, and try again.
• Tilt the dish slightly from side to side. What happens? Jot it down.

The ink in dry erase markers is engineered to be slippery. It’s made with a chemical that causes it to easily release from surfaces. (Permanent markers are made with a chemical that makes the ink stick to surfaces, so be sure not to use these in your experiment!)

The easy-release ink lets go from a surface, but why does it float? There are two reasons. First, dry erase ink isn’t soluble, which means it won’t dissolve in water. Second, dry erase ink is less dense than the water, so it becomes buoyant, meaning it can float. When you tilt the dish, the fish moves around on the water’s surface.

Brush, Brush!

This one will really get them into brushing their teeth once they scientifically prove all the good things that toothpaste can do.

• Write on sticky notes: Soda 1, Soda 2, Juice 1, and Juice 2. Place them in a row on a counter.
• Fill two glasses halfway with brown soda and place behind the Soda 1 and Soda 2 sticky notes. Fill two glasses halfway with lemon juice and place behind the Juice 1 and Juice 2 sticky notes.
• Carefully place one egg in the bowl. Squeeze a big dollop — about one tablespoon — of toothpaste on top of the egg and gently rub the toothpaste all around with your hands until the egg is completely covered in a thick layer of toothpaste. Repeat with a second egg.
• Gently submerge the toothpaste-covered eggs into the liquids: one egg in the glass labeled Soda 1 and the other egg in the glass labeled Juice 1. Wash and dry your hands.
• Gently submerge the remaining eggs, without toothpaste on them, in the remaining glasses: one in the glass labeled Soda 2 and the other in the glass of juice labeled Juice 2. Wash and dry your hands. Leave the eggs in the glasses for 12 hours.
• After 12 hours, remove the eggs from the glasses of soda one at a time. Rinse them in cool water and pat them dry with the towel. Place each egg by the sticky note of the glass it was in. Are the eggs the same or different colors?
• Remove the eggs from the glasses of juice one at a time. Rinse them under the faucet and pat them dry. Place each egg by the sticky note of the glass it was in. Feel the eggs gently. Does one feel stronger or weaker than the other?
• Write down your observations in your science notebook.

The eggshells in this experiment represent the enamel (outer coating) on your teeth. Toothpaste cleans your teeth and prevents stains: it removes food and drink particles that are stuck on your teeth. Teeth can be stained easily by dark-colored liquids like cola, coffee or tea. The egg without toothpaste will be brown and discolored. The egg covered in toothpaste was protected from turning brown.

Toothpaste also protects your pearly whites from decay (breaking down). The egg without toothpaste left in the lemon juice was worn down and soft to the touch, while the egg that was protected with toothpaste is stronger. The lemon juice is acidic, and those acids broke down the shell just as acidic drinks can wear away your tooth enamel. When a tooth is worn down, a cavity can form more easily. But the fluoride in toothpaste mixes with your saliva to create a protective coating around your tooth enamel. It helps keep your teeth strong and cavity-free.

Grow an Avocado Tree

For an easy lesson in Earth Science, your family can grow an avocado tree from a pit. You can buy an AvoSeedo kit , or just peel the seed and suspend it over water with toothpicks.

Milk Bottle Xylophone

No for an experiment in sound!

• Arrange six glass jars or bottles, all the same size with no lids, in a line. What will each jar sound like when you tap it with a spoon? Make a prediction, then tap each jar. Record your observations.
• Next, put water in each of the jars. Pour 1⁄4 cup (60 ml) of water into the first jar. Add 1⁄2 cup (120 ml) of water to the second jar. Continue in 1⁄4-cup increments, adding 3⁄4 cup (180 ml) of water to the third jar, 1 cup (240 ml) of water to the fourth jar, 11⁄4 cups (300 ml) of water to the fifth jar, and 11⁄2 cups (360 ml) to the sixth jar. Add a couple of drops of food coloring to each jar.
• What will each jar sound like? Will they sound the same or different than when the container was empty? Will they sound the same or different from one another? Record your predictions.
• Tap each jar with a metal spoon. Write down your observations about each jar’s pitch (how high or low a sound is) in your notebook.

Sound waves are created by vibrations, which are back-and-forth movements that are repeated again and again. Pitch depends on the frequency of the waves — how many are created each second. A high pitch is created by high-frequency sound waves, and can sound squeaky. A low pitch is created by low-frequency sound waves, and sounds deep and booming.

When you tapped the jar, it vibrated. The vibrations traveled from the jar to the water to the air and eventually to your ears. The jars with more water had a low pitch. The sound waves vibrated more slowly because they had more water to travel through. The jars with less water had higher pitches. The sound waves vibrated faster because they had less water to travel through. A jar with no water in it makes the highest pitch because it has the least substance to travel through.

"Elephant Toothpaste"

Okay, elephants don't really brush with this stuff, which is made from a chemical reaction between hydrogen peroxide, yeast, dish soap and a few other simple ingredients. But this experiment has a big "wow" factor since, when the substances are mixed, the "toothpaste" foams out of the bottle. You can use it to teach kids about catalysts and exothermic reactions.

Coin Inertia

Stack up about five or so coins on a piece of cardboard and place it over a glass of water. Then, flick the cardboard out from on top of the glass. Do the coins drop into the water, or ride with the cardboard? Due to inertia, they drop into the water — a very visual (and fun!) demonstration of Newton's First Law of Motion.

Apple Oxidation

What works best for keeping an apple from turning brown? Test to find out! Slice up an apple, and let each slice soak in a different liquid. Then take them out, lay them on a tray, and check the brownness after three minutes, six minutes and so on. Not only does this test the properties of different liquids, it also helps students practice the scientific method if they create hypotheses about which liquids would be most effective.

Coffee Ground Fossils

By making a salt dough with coffee grounds and pressing various shapes into it (toy dinosaur feet, seashells), kids can get a better understanding of how fossils are made. If you poke a hole in the top before it dries, the kids can hang their "fossils" up in their rooms.

Chromatography Flowers

Chromatography is the process of separating a solution into different parts — like the pigments in the ink used in markers. If you draw stripes around a coffee filter, then fold it up and dip the tip in water, the water will travel up the filter and separate the marker ink into its different pigments (in cool patterns that you can display as a craft project). This family made the end-result even brighter by adding an LED circuit to the center.

Water Walking

You'll need six containers of water for this one: three with clear water, one with red food coloring, one with blue coloring, and one with yellow coloring. Arrange them in a circle, alternating colored and clear containers, and make bridges between the containers with folded paper towels. Your kids will be amazed to see the colored water "walk" over the bridges and into the clear containers, mixing colors, and giving them a first-hand look at the magic of capillarity.

First Day of School Science Experiments and Activities

by Chloe Campbell Leave a Comment

Heading back to school is one of the most exciting times for a teacher – new starts, new kids to love on, and new opportunities to engage them in fun science lessons! I love pairing back to school community building with science experiments, and I’ve put together some of my favorite First Day of School Science Experiments and Activities for you.

These activities get students back into the swing of things, including activities and experiments around the scientific method, science investigations and variables, and the nature of science. Did I mention these are tons of fun and your kids will be super engaged?! Come explore how I run my science classroom during the first week of school to capture my students’ attention, all before I hop in to my science curriculum.

First Day of School Science Experiments and Activities: Back to School Science Labs

I want my kids to absolutely love science, so what better way to get them excited for the first day of class then to engage them in experiments that capture their attention? I have  five back to school science activities and experiments  that I love to do with my students, and they use simple materials you probably have on hand in your classroom already.

• First, I lean into my kids’ love of popping things and give them permission to do that in a controlled setting. We complete the “pencil in a baggie” experiment where we fill Ziploc baggies with water, and then poke holes through it with a pencil. The goal of this experiment is making predictions and then analyzing what happens, and we can talk about polymers and how they create a seal around the pencil piercing. My middle school students LOVE this one!
• To work on variables, we test out the strength of different brands of glue sticks. Students glue two pieces of paper together with three different brands of glue sticks, and then they analyze which glue stick works best based on how well they stay stuck together when they dry. This is great for practicing that we have to control variables, and only one thing (the glue brand) can change.
• For practice with trials and measuring distance, students make hoop flyers with paper and straws and then measure the distance they travel in three separate trials. I also include the engineering process in this lesson as students try to improve their designs so their flyers travel farther.
• One of the most fun challenges I do with my kids during the first week is a cup challenge. Students are tasked in building cup towers with two distinct goals. First, students need to create the tallest structure they can. Then, students create the strongest structure they can. The competition level is always fun to watch, and it really keeps my kids invested in the challenge. Bonus: this one doubles as a STEM challenge!
• Finally, students set up their final challenge, which lasts a few weeks. In this experiment, students put three pieces of bread into baggies with different conditions. One baggie has bread (control), another baggie has bread that has been touched by soapy hands, and the third baggie has been touched by hand sanitized hands. Students make predictions about what will happen to the pieces of bread over time, and we watch what happens over the next couple of weeks.

First Day of School Science Experiments and Activities: The Scientific Method

Middle school science teachers need their students to understand how to use the scientific method in their classes, so practicing this skill is a must in my classroom during the first days of school. Here are some of my favorite beginning of the year science activities.

Sometimes, my kids come in with limited understanding of the steps of the scientific method, and a review of the steps is beneficial for everyone anyway. This is a favorite fun activity that my students rave about each year! Students practice learning the following  steps of the Scientific Method :  Ask a Question, Form a Hypothesis, Design a Controlled Experiment, Collect and Analyze Data, and Draw a Conclusion.

This activity is general in nature and provides an overview of the concepts. First, we create a foldable with information about each step. Then, students complete an experiment where they measure the effectiveness of various paper towel brands and their absorption of water. I don’t know why, but my kids love getting paper towels wet!

 To practice  the three different types of variables ,  students work on an investigation where they choose three different ways to make ice melt. First, we review dependent variables, independent variables, and control variables . Then, students can choose from several variables to melt the ice cubes they are given, such as sand and salt. Students monitor their ice over a 15 minute span and measure the progress of the melting three times.

To help students understand that experiments  using the steps of the scientific method should be replicable , students complete a lab activity where they design a distance experiment. Students measure how far a ball travels after rolling down a ramp. They need to lay out the steps of the experiment as clearly as possible so that someone else could replicate their experiment with ease. This one is harder than it seems, but it is so important for students to understand!

In earlier grades, upper elementary students learn how to take data and why data is so important. In science classes for older students, we need them to understand the difference between  qualitative and quantitative data . First, students make observations and then decide if a piece of data is opinion based or verified by evidence. Then, students complete a second set of observations to practice identifying qualitative data and quantitative data. For my class, I use three different candy bars, but you can use anything that students can take both forms of data on.

One thing I always find that my students need to understand WHY we do this in experiments is  why we do multiple trials of an experiment .  If our students could do one trial and call it a day, they might, so it’s important they understand why repeated trials are important. To achieve this goal, students bounce a ball on five different surfaces. They measure what happens to the ball on each surface 5 times, for a total of 25 ball bounces. This is a simple experiment that achieves a strong goal to make sure students understand the importance of repeated trials. My kids love this science activity!

To  compare and contrast experiments and investigations , students complete a Venn diagram comparing these two science terms. Then, students work through a paper airplane experience where they must decide if they’re doing an experiment or an investigation. Students complete this activity in small groups, and it’s a great way to build community and science concept building at the same time!

First Day of School Science Experiments and Activities: Games

You know your kids love playing games in class, and whenever I can include a game in science class, it’s always a hit! I generally use these games once we’ve completed the activities above, but these games can be played right away as well if your kids come in with a lot of knowledge about the Nature of Science and the Scientific Method.

Game 1 is about the  Nature of Science , and it includes practice with important science concepts and content vocabulary like inference, conclusion, problem solving, and the questions promote critical thinking skills.

Game 2 is about  Control Groups and Experimental Groups , which are important concepts that students can sometimes be confused on.

I know you’ve got a lot going on at Back to School time, so I’d love to help plan part of your start of the school year. I’ve put these resources together in a one-stop-shop bundle, which you can grab by clicking the picture below. AND, as an added bonus, you get my first three weeks of school lesson plans – done for you!

I know your beginning of the school year will be wonderful, and your students are so lucky to have you! I am confident these back to school activities will be beneficial to you and your students. Have fun doing these scientific investigations and easy science experiments with your kids this back to school season. Have a great year, science teachers!
