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

Learn with makes water molecules work with this fun and easy science activity!

This science fair project idea produces sounds by creating vibrations using different objects.

This science fair project demonstrates the principles of reflection through simple experiments involving mirrors and light.

Using simple materials found around your home, you can reinforce the static electricity concept by helping your child build a simple device with zapping power!

All you need are pencils, paper and some scissors to get started on this easy and fun game to review astronomy information, or other types of study concepts.

The purpose of this science fair project is to build a basic radio.

This science fair project idea explores the relationship between oil and water in terms of density as well as hydrophilic/hydrophobic compounds.

Students pit the heat capacity of water against the heat capacity of oil while looking at the effects of dipole rotation in this cool science fair project idea.

Sink or swim? Calculate the density of various fruits and vegetables using water and a kitchen scale.

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