This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

Kids will make a beautiful rainbow in a jar and learn what enables different types of liquids to remain distinct in separate layers.

Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?

In this science fair project, students discover how sedimentary layers form as sediments like mud, silt and sand settle over time.

How does a flashlight work? Kids will make a complete circuit and explore how voltage contributes to brightness with this science fair project idea.

Understanding absorption means understanding why certain fibers and materials can absorb water! Kids will see absorption in action in this simple project.

In this fun activity, your child will create their very own solar oven to bake s'mores!

Why doesn't the ocean freeze? Students answer this question by simulating the chemical composition and temperature of arctic waters in their own home.

In this design challenge, your child will make a bottle rocket using typical household items.

The objective of this science fair project is to observe the differences in heat absorption for darker colors vs. lighter colors.

Do hand soaps and sanitizers prevent the growth of bread mold? If so, why? Kids will find out with this fun and informative science fair project idea.

How does a compass work? What's a magnetic field? Kids will build their own compass at home to find the answers in this great science fair project idea.

The objective of this science project was to build a model of a volcano and observe reaction between different substances, including baking soda and vinegar.

How can we describe the relationship of magnetic field strength vs. distance? Kids will find out with this free science fair project idea.

How powerful is the reaction between baking soda and vinegar? Find out here!

Reinforce your child’s understanding of the alphabet by helping them construct all of the letters using pipe cleaners.

Kids will learn some cool stuff about chemical reactions by determining what happens when you mix different concentrations of hydrogen peroxide and yeast.

Challenge your learner to design and build a city of their own in this creative engineering activity.

By incorporating natural materials and the powers of observation, your child will become a backyard naturalist while building early writing and drawing skills!

The goal of this fun science fair project idea is to microwave candy and investigate: do some colors of M&Ms melt faster than others?

How does smell affect taste? Ready your taste buds--in this project, you'll gather some test subjects and do a taste test to see how much smell affects taste.

While your cells are much too small to see without a microscope, you can create the look of a cell in your very own home with just an egg and vinegar!

In this hands-on design challenge your child will make their very own Rube Goldberg Machine.

Dinosaurs were huge creatures that left behind huge footprints that lasted for millions of years. In this science fair project, kids learn how dinosaur tracks were left behind!

Have your child kick off their summer vacation by making a miniature water slide!

Is it magic? No...it's the amazing, gravity-defying capillary action experiment! Kids will love this dramatic and enlightening science fair project.

In this exciting design challenge, your child will use design thinking skills to create a mixture that can inflate a balloon.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.
