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

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.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.

This science fair project idea produces varying pitches of sound.

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

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

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