What is elasticity? Students will investigate how this concept applies to bouncing ball physics by testing the bounces of balls made out of different materials.

In this free science fair project, learn how to separate salt from water using heat. A great science project for elementary school kids.

How does rust form? Kids will learn about the roles oxygen, water, and electrons play in rust chemistry in this cool science fair project idea.

Set your young chemist up for an afternoon of science-fueled magic with a deceptively simple activity starring baking soda and vinegar!

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

Most people assume that cold water freezes more quickly, but could that be false? Does hot water freeze faster than cold water? Let's find out!

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

This science fair project idea experiments with spinning color wheels and optical illusions.
