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 produces varying pitches of sound.

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.

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

This science fair project examines how tsunamis travel by simulating a tsunami moving around an island. You will generate a pretend tsunami in a swimming pool.

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

How does the size of a vibrating surface affect the pitch of a drum? Learn about drum size and pitch with this easy science fair project idea.
