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 science fair project idea shows how a vibrating object transfers energy to whatever it touches.

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

Make stunning pendulum waves and learn the math behind the patterns generated with this cool and easy science project.
