This classic children's game demonstrates how sound travels through air vs. through a solid.

Kids conduct a cool balloon rocket experiment in this fun science fair project idea. Does a greater volume of air mean a greater distance traveled?

In this science experiment, do tensile strength test on fishing line, a strand of hair, a rubber band, and any other materials you're curious about!

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.

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 simple science project, learn about what causes dew and what affects dew formation with a drinking glass, ice, and a soda bottle.

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

In this fun experiment, we'll find out how color affects heat absorption!

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

How do series and parallel circuits work, and which produces the brightest light in a light bulb? Construct both in this project and find out!

Kids will love making sugar crystals in this sugar crystal science fair project which teaches important chemistry concepts like saturation and solubility.

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.

These science fair experiments demonstrate the chemistry of rust and the oxidation process.

This science project uses Mohsâ Hardness Test to show kids how to compare the hardness of different types of minerals.

This science project challenges students to study deer behavior in their natural habitat- the feeding patterns, social behaviors, male to female ratio, etc.

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

In this project combining nature, art, math, and science, children make rubbings of leaves then observe shapes and structures and sort the leaf images.

Ever wondered how a plant drinks water? This science project will teach you how and help you create a beautiful floral display!

Will potatoes spud or sprout faster in dry, dark, or cold conditions? Find out in this science fair project idea!

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

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

In this science fair project, students make their own rain gauge to measure rainfall.

Students will investigate the thermal conductivity of metals by learning how to measure thermal conductivity with this fun and easy science fair project idea.

This science fair project explains the process of how the lungs expand and contract with the help of the diaphragm.

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

Why does honey crystallize? This science fair project project answers this question and identifies the variable that makes this sweet solute crystallize faster.

In this science fair project, learn how to make gears and find out why they transmit torques in predictable ways.

With this cool floating rocks project, your child will get some hands-on experience with buoyancy and learn why certain rocks like pumice are able to float.

This science project teaches young students about germs, bacteria, and the importance of washing their hands. Students will test what is the best way to wash.
