How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

This activity provides a solution to all those leaves on your doorstep, while also giving your child a fun science lesson.

In this science fair experiment, children demonstrate the relationship between the amount of stuff and the amount of pressure in a closed system.

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