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.

In this simple circular motion experiment, you'll observe tangential velocity and learn about how acceleration and centripetal force affect an object.

Can a toy car determine the strength of a magnet? In this cool magnet science fair project, young scientists will learn how to measure the strength of a magnet.

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?

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

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!

In this fun science fair project, make two different scale models of our solar system using Astronomical Units and planets' relative size!

Saturn is the ringed planet in our solar system, a gas giant with rings made of ice and dust. Let's make a cool scale model with an old CD and some glitter!
