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 activity, you'll not only make your own bouncy balls at home, but your child will also learn how polymers are made.

Science fair project in which you will attempt to throw a ball the greatest horizontal distance possible by using different angles.

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

Find out whether optical mice are useful on all surfaces or if there are drawbacks to this supposedly superior solution to the traditional roller-ball mouse.

This science fair project idea determines if the temperature of rubber effects how high it bounces.

This basketball project explores the best way to make the perfect shot every time.

In this science fair project, students learn how pressure can make the minerals in a rock line up in the same direction and form bands and foliation.

This science fair project idea measures the growth of bread dough and finds out how long it takes for the dough to stop rising.

In this experiment, students will discover how heat and pressure turn clay into slate, phyllite, and finally schist.
