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.

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.

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

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.

Managing Science Experiments

Seashell experiment, ice melting experiment, water cycle in a bag, making snow, states of matter, easily fit science into your schedule.

A lot of science experiment opportunities are lost due to the time, materials and classroom chaos managing that is required. Hands on activities do require a bit more management and preparation, but the learning that ensues is worth it, I promise!

Teach Experiment Routines & Procedures

Just like any other classroom activity, the routines and procedures for the science experiment need to be explicitly taught. Procedures to teach include:

• Getting materials
• Following the experiment directions in order.
• Filling out experiment worksheets
• Monitor class volume and discuss the appropriate levels for the activity.
• Putting away materials & cleaning up work space
• Stick to your group role

Assign Roles

As mentioned in the above section, you should assign group (or partner) roles for students to stick to. This gives them a focus, keeps the group on task and squashes the arguments over who does what.

Use partner cards to assign roles in a snap.

Before sending students off to complete their experiment, model how to gather their supplies. Safely hold or use them, and what each member of the group will be doing. Do not model the entire experiment, as this takes away the science magic!

Let's kick off our science experiment list with one that will make you think of long walks on the beach.

Materials Needed:

• Seashells (They can be gathered, purchased at craft or dollar stores, or ordered on Amazon .)
• Jars or cups

Directions:

• Place a few seashells in a jar.
• Fill the jar with vinegar.
• After a day or two, observe what happens to the shell.
• Replace the vinegar and observe for another day or two.

We all know ice melts, but are there materials that melt it faster than others? Students will get excited watching this melting “race”.

• 4 ice cubes
• 4 cups or bowls
• 1/2 cup of 3 different materials like warm water, cold water, salt, sugar, sand, flour, etc
• Put an ice cube in each cup.
• Pour 1/2 cup of a material on the first 3 cubes.
• Leave just the ice cube in the last cup.
• Check on the ice cubes every 5-10 minutes.

Tell your students you can make it rain inside a Ziplock bag. They will be astounded! This science experiment is a great visual of the water cycle in action.

• Ziplock gallon bags
• Sharpie markers
• Food coloring
• Optional: have students draw a design on their baggie, such as clouds, raindrops or waves.
• Fill the bag 1/4 of the way with water.
• Add food coloring.
• Seal the bag.
• Hang in a sunny window & observe the water cycle!

Bonus tip : a hair dryer can speed up the process, just don't hold it too close to the baggie!

No matter the time of year, or where you live, you can bring a little snowy magic into your classroom.

• 1/2 cup baking soda
• 3 tablespoons white hair conditioner

1. Pour baking soda into a bowl.

2. Have students identify what state of matter the baking soda and conditioner are.

3. Predict what state of matter it will be when the two materials are mixed.

4. Stir the two together to make the snow. Identify the new state of matter.

Many states list states of matter as a 2nd grade science standard. Why not use a science experiment that will last a few days and demonstrates all states of matter?

• A cup or bowl
• Discuss the states of matter using pictures of each state. Here is a ready to go unit.
• Start with the solid state: put an ice cube in a cup. Discuss which state of matter will occur when you leave the ice in the cup.
• Observe when the ice cube has melted. Then, discuss which state of matter will occur as you leave the water. (Evaporation-gas!)
• Observe how long it takes for the water to completely evaporate.

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. 

• Balloon Rocket From Scishow Kids

This is one of the most fun 1st grade science fair projects and it introduces the laws of motion and forces. During this project, students will observe when we blow the balloon up with more air, it should travel farther. Students will need to observe, measure, and record data. 

• String (2-3 yards length recommended)
• 2 chairs or other object to tie each end of the string

Download this Hands-On STEAM- Physical Science e-book for supporting materials by Classroom Complete Press. 

• Fluffy Slime Experiment From Elmer’s Store

This is a fun and easy experiment where 1st graders learn how to mix multiple substances to create one new substance. I like the Elmer’s Fluffy Slime Kit set linked below as it makes two batches of soft, fluffy slime in two colors.

Pair this experiment with activities from this Hands-On- Physical Science: Matter & Materials unit for a lesson about states of matter by Classroom Complete Press. Have students discuss which state slime might fit into and why. 

• Crayon Box STEM Activity By The Core Coaches

This project is designed to help your students think outside the box and learn how the world works. It helps students explore the engineering design process using common materials.

This digital download includes a list for material recommendations, but this challenge can be done with materials you have on hand, such as:

• Pipe cleaners
• Popsicle sticks
• Cotton balls
• Rubber bands
• Leaf Chromatography Project From Lostronaut’s Store

When learning about the four seasons, a natural question for first graders to ask is why leaves change colors in autumn. 

To start this project, use a Seasonal Cycles Worksheet by Have Fun Teaching, to develop background knowledge prior to the experiment. 

Next, have students go outside and collect different leaves. Break the leaves up, put the pieces in a cup, and add rubbing alcohol. Then use the chromatography kit linked below to set up the strips and watch the color bleed up. Discuss the different colors that separate out during the chromatography process.

• Dancing Rice From Farmingdale Library

Dancing rice is the perfect chemistry experiment for first graders because it demonstrates a chemical reaction. When vinegar is added to baking soda, the hydrogen ions in vinegar react with the sodium bicarbonate in the baking soda and releases gas. 

• White vinegar
• Baking soda
• Optional: Food coloring 
• Shoebox Guitar By Twin Sisters Digital Media

What’s better than conducting a science experiment about sound? Use the shoebox guitar project to teach students about vibrations and how sound travels. Then make some classroom music and dance out all that 1st grade energy.

• 4 rubber bands of varying thickness

Living vs Nonliving: Yeast vs. Sand

This first grade science experiment compares the properties of yeast and sand which look similar, but one of them is living and the other is nonliving. 

Use this activity to spark a conversation about the properties of living and nonliving things and what all living things have in common. 

This STEM Workbook and Living and Nonliving Things activity pack provide worksheets and activities to support learning about living vs. nonliving things. 

• Sink Or Float From Mayta The Brown Bear 

This fun lab is a great introduction to the concept of density. 

Gather whatever items you have on hand and a large bin of water. Have students make predictions about which items will sink and which will float. They can test objects like a small sheet of tinfoil, a pebble, a flower, a leaf, a stick , a marble, etc. 

You can also use this Sink or Float Recording Sheet to collect data by Cherry Workshop. 

• Blubber Experiment From Learn With Mrs.B

In this experiment, students investigate the insulating properties of shortening or petroleum jelly as a substitute for animal fat. 

• Plastic zip baggies 
• Lard (shortening) or petroleum jelly
• Bowl of ice water

Combine this experiment with a lesson about arctic animals using some Polar Animals Flashcards by Fiddleticks Education or with this animal science unit All About Polar Bears to teach them how arctic animals stay warm in their polar environment by Simply Schoolgirl. 

• Fossil Factory By Twin Sisters Digital Media

Get your students ready for a fossil adventure. First graders can design their own fossil out of clay and then go on an outdoor field trip to dig around for fossils outside after learning a bit more about them.

• Natural objects
• Rolling pin
• Plastic knife
• Paint brush
• Cloud In A Jar Experiment By Lilibette’s Resources

When learning about either weather or the water cycle, creating a cloud in a jar is the perfect activity to show children how clouds are formed when warm water vapor rises toward cooler temperatures and attaches to condensation nuclei. Specific instructions on how to make the cloud in the jar are available in the Clouds Mini Project Resource Pack below.

• The Penny Experiment From Kids Fun Science

This super easy experiment demonstrates the properties of water cohesion and surface tension. Start with a testable question like “How many drops of water fit on the head of a penny?” 

Children should make their predictions. Let students design an investigation to answer the testable question. This experiment lends itself to teaching the scientific method . 

• Cup of water
• Create Your Own Tornado From The 4M Store

Who doesn’t love learning about how storms form? First graders will have fun putting their model together and simulating a tornado from this kit full of everything you need. 

For further learning, have students listen to an audiobook, Tornados and Hurricanes by Twin Sisters Digital Media

• How Many Pennies Can My Boat Hold? From KSU iTeach

In this experiment children will design and construct their own tinfoil boat. Then they will predict how many pennies the boat can hold before it sinks. 

This experiment demonstrates the property of density. 

• Bucket of water

A Water Experiment Journal by Kindergarten Cafe that includes a worksheet for students to collect data and record their observations is a great supplement.

• Making Rock Candy From The Sci Guys

This chemistry experiment shows students how increasing water temperature causes sugar to dissolve. You can also show your children how sugar doesn’t dissolve in cold water. As you increase the temperature, it begins to dissolve, creating a new solution that results in a sweet treat everyone can enjoy later. 

• Optional: Flavoring
• Elephant’s Toothpaste From Michigan Medicine

Students will learn in this project how different substances react to create a new substance, and, in this case, heat energy. The yeast removes the oxygen in the hydrogen peroxide, causing bubbles. Heat energy is released, creating what is known as an exothermic reaction. 

• Food coloring
• Plastic water bottle
• Hydrogen peroxide
• Liquid dish soap
• Measuring cup
• Paper plate
• 1 tablespoon of dry yeast
• Grow Your Own Crystals From The 4M Store

A favorite 1st grade science project is growing crystals. You can do this with a pre-packaged kit, like the one linked below, or with a variety of household items, including Borax. 

Crystals form when water evaporates from a mixture. You can also teach your first graders about the different geometric shapes that crystals form. And this can be paired with a lesson about evaporation using these The Water Cycle Printables by My Kind of Crazy. 

• Shiny Penny Experiment From SciShow Kids

This experiment introduces the concept of variables in a way that first graders can easily understand. Students will use a number of different substances to polish dull pennies. The independent variable is the substance being tested to polish the penny. This is the variable that we are manipulating or changing. 

• Can of cola
• Lemon juice
• Tarnished pennies
• Build Your Own Rain Gauge   From Community Play Things

When learning about weather, have students make their own rain gauges. When it rains, they can make predictions about how much rain will fall and collect data on the actual amounts. 

Resources for this lab and other weather related activities can be found in Teach Simple’s Hands-On STEAM- Earth and Space Science Grades 1-5 by Classroom Complete Press.

Students may also be interested in the audiobook When I Grow Up, I Want to Be a Meteorologist to supplement the concepts learned by Twin Sisters Digital Media.

• White flower
• Jar of water

To learn more about plants and their parts, you can couple the experiment with the book: Plant, Plant, What Do You See by Kindergarten Cafe. 

• Jumping Frogs (Static Electricity) From Science Sparks

This is a fun take on using a balloon and rubbing it against fabric to create static electricity. 

Have students predict how many paper frogs will be attracted to and stick to the balloon. Another variation on the lab is to have students time how long the frogs stick to the balloon. 

Supporting materials to teach about static electricity can be found in this resource: Hands-On Physical Science: Electricity and Magnetism . 

• Popsicle Stick Catapult From stlDenise3D

Children will create a catapult with a plastic spoon, popsicle sticks, and rubber bands. 

After constructing the catapult, ask children to choose objects to launch. Some suggestions include marshmallows, cotton balls, and other soft items. 

Students can predict which objects can be launched the farthest. Teach Simple’s unit on Force and Motion by Classroom Complete Press reinforces the concepts in this 1st grade science project. 

• Oreo Cookie Moon Phases From Hungry SciANNtist

Learning the phases of the moon can be challenging. So why not make it fun by using Oreo cookies to model each phase of the moon? 

Students can easily create their own model in groups or individually. 

Then have students review the moon phases using some Moon Phases Flashcards by Fiddleticks Education or this It’s Just A Phase activity to further reinforce the concept by Have Fun Teaching. 

• Rolling Pin Pulley From STEM With Mr. C

In this first grade science fair project, children will learn the mechanics of simple machines by constructing their own pulley. Engage students in a discussion about where they might see pulley systems in the world around them. 

Then, use a Hands-On Physical Science: Simple Machines activity pack to introduce the mechanics behind simple machines by Classroom Complete Press. 

• How Does Composting Work? From Educational Insights Store

Americans waste about a pound of food per person each day. Composting has become a popular way to let food waste decompose rather than throwing it away. But how does it work? 

Try out this easy classroom compost kit and let students make observations over a number of weeks as they watch what happens when different types of materials decompose.

This project can be an extension of Teach Simple’s lesson on the Flower Life Cycle by My Kind of Crazy or Watermelon Life Cycle by My Kind of Crazy. 

• Fun With Ramps By Twin Sisters Digital Media

The perfect 1st grade science project can be found in Teach Simple’s Science Projects: Volume 1 resource. Your 1st graders will have fun sending different objects down ramps and comparing how far each object travels. They can also change the incline of the ramp to test whether that affects how far objects will travel. 

• Flat moveable surface to use as ramp
• Rollable objects
• Marker Chromatography From Science Kids

This fun experiment combines science and art. Students will learn how substances are made up of more than one component by separating colors from ink samples through the capillary action of the water traveling through filter paper. The water dissolves the ink, causing colors to separate. 

• White coffee filters
• Washable markers
• Craft stick
• Binder clip
• Paper towels

Use this activity in conjunction with other activities from Teach Simple’s Colors Science, Literacy and Math Activity Packet by KP Classroom

Light & Sound Activities & Lesson Plans for First Grade

Teaching Science has definitely  not been my favorite subject to teach…even in first grade! It always seemed so challenging to explain such difficult concepts to kids! I’m hopeful these ideas for teaching light & sound worksheets and activities will be as helpful for you as they were for me. 👇

I’m not gonna lie…I often pushed Science off in my plan book because I wouldn’t want to face the questions from first graders {lame, I know!} When my school district decided to move over to the Next Generation Science Standards, I knew I had to get ahead of this curve and dive in deep. I set out to create easy to understand and do science lessons!

I am SO excited for my first unit in the 1st Grade Standards, Sound & Light ! You guys, this labor of love was created so that ALL of us can easily teach the NGSS and actually understand it!

This unit is chock-full of step-by-step lessons, experiments , anchor charts, book suggestions, YouTube videos , response sheets and more to make sure your students understand Sound & Light through hands-on experiments and investigations.

Each lesson includes a learning target, background information, talking points, a book suggestion, and

Background Info for the Teacher & Prepping for Lessons

When I taught from our Science curriculum, I was always so overwhelmed by how much background info was provided! Was I going to be tested at the end? Eeeek!

In this Sound & Light Investigations unit  I’ve shared  just the right   amount of information to totally “get” what you’re teaching! There are also easy-to-understand vocabulary posters to help your students understand these big ideas!

Each of the investigations uses super simple materials that you have around your classroom or can easily get from parents.  I’ve included a Materials List to make gathering these goodies easy!

I’ve also included a Family Letter to inform your students’ families about what they’re learning about!

What is a Scientist? Activity

Kick off the unit by chatting about what being a scientist actually means!

Kids L•O•V•E science! Get them thinking about just what a Scientist does! It’s fun to gauge their thinking and start meaningful conversations about science.  The bonus is that your students will start to see themselves as scientists!

I had SO much fun doing these experiments when I was making this unit, so I am certain you will, too! The best part – your students will  definitely have fun and learn about light & sound along the way!

Sound Activities & Lesson Plan Ideas for 1st Grade

You’ll start this set of sound explorations by taking your kiddos outside for a sound hunt.  Give them a while to explore and record the sounds they hear using their senses.  They’ll fill out a mini book and add their sounds to a poster.

Once your students have an awareness that sound is  everywhere , you’ll move into lessons to get them making sounds and understanding sound waves.

This kazoo is SURE to be a hit in that exploration!

In the following lessons, students will continue to explore how sound moves and how they can change the sound things make.  Simple supplies from around your classroom will give students a chance to make their very own instruments!

Thankfully I had this cutie to help me test out this hanger instrument! This lesson helps students see how sound moves through different materials.

The final lesson in the sound exploration gives students a chance to see how sound moves through solids, liquids & gases.

By the end of these experiments, students will have a good understanding of sound! I’ve included book suggestions, YouTube links, and additional ways to extend the lessons!

Light Activities & Lesson Plans for 1st Grade

Here’s a peek at all the lessons for sound.

To start, your students will explore why light is needed! Without light, we can’t see anything!

Then, you’ll move into a discussion about Natural vs. Artificial light.

The students will follow up the discussion with this PowerPoint game.  Check out a sneak peek below!

After understanding that light is necessary to see and that there are various ways to see light, you’ll move into a bit meatier ideas.  In the next lesson, kids will investigate different materials to see how light reacts.

Grab some cheap flashlights from the dollar store and a few different cups and you’re all set to go!

Through exploration, the students will see that light affects transparent, opaque, and translucent materials differently!

By far, my favorite lesson is #4 – Eye Tricks!

Students will do a light experiment to see just how refraction works! I bet this will be a crowd pleaser in your classroom!

Check it out in action!

Have you ever met a kid who  doesn’t love a mirror? Well, turn that fun and curiosity into some learning with these explorations. 

Students will explore with mirrors, toys, and lights to see what happens with light!

To wrap up your light study, you’ll give students a chance to head outside and explore shadows!

Lesson Ideas to Better Understand Sound & Light

To show their learning, students will wrap up the unit combining their knowledge of sound and light!

First up, they’ll create a telephone using string and cups. Don’t you remember doing this when you were a kid? Now, you can do it again…and share the science behind it!

And the final project will be creating a way to communicate with a friend…without speaking! Your students are sure to get creative with this activity!

Recap of Sound & Light Activities and Lesson Plans for 1st Grade

I promise this entire Sound & Light Investigations unit is TEACHER friendly! The kids will have so much fun learning and exploring that they won’t even realize they’re learning those new Next Generation Science Standards!

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.

None of this is magic. It's all science that you can do at home, most likely with ingredients you already have in your house. So, next time you need a boredom-busting indoor activity on a rainy day or a DIY project to get their minds humming, try one of these best at-home science experiments for kids , which cover topics like cover magnetism, surface tension, astronomy, chemistry, physics and more.

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.

Paper Bridge

Get the engineering back into STEM with this activity, which challenges kids to create a paper bridge that's strong enough to hold as many pennies as possible. How can they manipulate the paper to make it sturdier? (Hint: Fold it!)

See the paper bridge tutorial at KidsActivities.com »

Challenge your little scientist to lift up an ice cube with just a piece of string. It's possible ... with a little salt to help. Salt melts the ice and lowers the freezing point of the ice cube, which absorbs the heat from the water around it, making the water cold enough to re-freeze around the string.

Leaf Breathing

It's hard for kids to picture how plants and trees "breathe" through their leaves — until they see the bubbles appear on a leaf that's submerged in water. You can also teach them about photosynthesis by putting different leaves in different spots with varying levels of sunlight.

Hoop-and-Straw Airplane

We all remember how to fold those classic, triangular paper airplanes, but these hoop-and-straw airplanes fly way better (and straighter). Experiment by changing the length of the straw and the size of the hoops and see how it affects the flight.

Film Canister Rocket

Blast off! You don't need jet fuel to make these rockets go, just Alka-Seltzer tablets and baking soda, but they'll be amazed when they achieve lift-off! (Note: If you can't find old film canisters, tubes of Airborne work, too.)

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.

Sound Experiments

This science unit is so fun. It’s loaded with my favorite sound experiments, like this one. I first saw this idea in a library book and, to be honest, I didn’t expect it to be that big of a deal (or even work, if I’m still being honest). But to my surprise, it actually delivered. I think I suffer from Pinterest-Fail PTSD.

Singing Spoons  is a fun way to show kids how volume and pitch change depending on whether sound waves are traveling through the air or through a solid, similar to the way a stethoscope works. It’s one of our favorite sound experiments and is pretty easy to set up. Just use tape to connect three metal spoons to a piece of string or yarn. Then, jiggle the string so the spoons swing into one another and observe the sound they make. It should sound dull and tinny. Next, wrap the ends of the string around your fingers as if you were going to floss your teeth. Place only the yarn-wrapped fingers in your ears (again, think of a stethoscope) and swing the spoons again. Notice how the pitch and volume change.

Even the adults in my house thought this was cool. And one of them is fairly hard to impress.😉

This experiment can easily be done without these sheets👇, but I like reading procedural and informational texts with my students and I also like having a place for them to record their own ideas during investigations.

More Sound Experiments

Hands down, the most satisfying part of planning this science unit was finally engineering a harmonica that actually works! I’m not exaggerating when I tell you how much we were geeking out over this one… maybe because it was our third attempt. But I guess that’s the nature of science experiments, right? In the one pictured below, changing the distance between the pink straws changes the pitch of the sound. Shorten the gap and the pitch will rise. Spread them back out and the sound will become lower. It’s all about vibrations and sound waves .

And the bee?🐝 If you swing it like a lasso above your head, it really does buzz! It’s another fun way to teach your students that vibrations cause sound.

I created student recording sheets for these sound experiments, as well as procedural posters (with picture support) and kid-friendly explanation sheets. These explanations help young children understand the science they’re observing, but I also like how they give families an age-appropriate context to build from when they want to talk to their kids about science.

Making a sound wave model takes some time, but the wow factor can’t be denied! You only need three things to make your model: duct tape, wooden skewers, and clay.  NOTE:  To save time, we built ours using jellybeans, but I think the weight of the clay would provide an even better result. If you use clay, roll each ball to roughly the size of a large grape.

Nonfiction Science Text

I have a hard time finding science material my first-graders can actually read, so it has become my habit to just write our own. It’s a win-win really because then I have a paper copy for each of them. By having their own, we can not only read it together, but the kids can practice it independently and even take it home to share with their families. The books serve double-duty during reading and phonics instruction, too. We can highlight key vocabulary words, find and circle word wall words, and even personalize the interactive pages.

This science book, What Is Sound? , introduces children to the concept of sound and how it behaves. Key science vocabulary such as pitch , volume , vibrate , and echo are emphasized in the text.

Key Vocabulary Posters

There are some pretty BIG words for some pretty young kids in this science unit, so I created a set of posters to help the children understand and remember them. Each poster features the key science term, a colorful graphic, and a kid-friendly definition. The set includes 8 different posters for the following vocabulary words:

• communicate

Key Word Game Cards

Mini-versions of the key word posters have been included in the resource. Originally, I just intended to use them as cards in a “Memory” style game, but they’re also good for student-pairing activities and vocabulary review. There are nine pairs of words in the set: sound, waves, vibrate, volume, pitch, echo, ear, communicate, and loud .

Student Worksheets

I also included some additional worksheets to help support science instruction and provide a connection to other subject areas, such as writing and phonics.

You can preview more of this first grade science unit👉   HERE . It includes printable materials for teaching children the science behind light and sound, as well as how we use both to communicate with others.

Science Ideas on Pinterest

Even though I teased about a Pinterest-Fail at the beginning of this post, I do love Pinterest. (I have discovered though, if it looks too good to be true, it probably is.😂) If you’re planning a science unit on the study of light and sound, click over to my Pinterest board:  Light and Sound Science . I’ve added pins that lead to great ideas for supporting your instruction. You’ll find science videos, book suggestions, integrated projects, and more.

Recommended Book List

Check your school or local library for titles to support your science instruction. These are some of the books I’ve used for read-alouds and to help build my own background knowledge as I planned the unit.

3 interactive weather science experiments for first grade

Weather science experiments are some of my very favorite to do with kindergarten and first grade kids. They are engaging, they provide powerful learning opportunities, and kids LOVE weather. Here are 3 kid-approved weather science activities that are easy to prep and sure to have your kids hooked on weather science!

did my shadow move?

This experiment will blow your kid’s minds! Every time I do this science activity with first graders, they are just so surprised, which makes it even more meaningful and exciting for everyone.

We do this shadow science experiment when we are learning about the patterns of the sun and day and night cycles. It is one of the first things we do before we jump into learning about the sun and the earth’s orbit.

Kids partner up and trace their shadows at the very beginning of the day and then make predictions on what will happen to their shadows.

At the end of the day, we come back out and retrace our shadows. And before they have even traced it out, get ready for the screams and giggles! It is SO much fun watching them realize their shadows have “moved!”

This shadow experiment blog post gives all of the nitty gritty details for how we manage this weather science experiment, how we record our shadow observations , and what we use to follow up with some powerful learning about earth’s orbit and the sun!

clouds in a jar

It took me a few years of teaching first grade weather lessons to get brave enough to do this weather science experiment with kids… and y’all! I have NO idea what I was scared of.

This weather science activity is super low prep with another super high learning impact! And anytime you can get shaving cream in the classroom… kids know you’re gonna have a good time! #iykyk

In this cloud in a jar weather science experiment , kids will fill their clear cup with water. We will put a shaving cream “cloud” on top of their cup of water.

Then, the kids will take turns dropping blue water on top of the “cloud.” They will predict and record how many water drops it will take before the cloud begins to rain.

This is another weather experiment where kids OOOOOH and AHHHHH when it starts raining in their cup. And it’s a powerful launch into a discussion about condensation and what makes a cloud finally start to rain!

The materials list and all the rainy details are in this cloud in a jar rain experiment post.

Catch a rainbow

At the risk of sounding like a broken record, this last weather science experiment is another one that is a real winner with a super high “giggle and wow” factor! Seriously!

In this rainbow science experiment , kids will shine a flashlight through a glass of water to try and catch a rainbow on their paper.

Must have for this weather science activity : classroom lights off! So, yeah, your kids will already be thrilled because turning the classroom lights off is like magic around here! 🙂

Rainbows, rain, and the water cycle are a big part of our first grade weather unit . But I have also done this experiment with preschoolers at church when we were learning about Noah’s Ark and it was easy for my 3-5 year olds too! (We just didn’t do all the writing!) This is such a great weather experiment for a wide age range of kiddos! Read all the extra details on the catch a rainbow science experiment here .

You can find all of these weather science experiments in this first grade weather unit . And you’ll find the catch a rainbow science experiment in this kindergarten Next Gen Science weather unit along with several other weather experiments!
