Echoes: How Sound Waves are Reflected and Absorbed

This science fair project idea explores the different parts of the human ear and models how the human ear reacts to sound waves.

In this cool sound resonance experiment, learn about frequency and pitch, and use a tuning fork to calculate sound velocity in air.

In this fun science fair project idea learn about the multiple sources of radio waves and fin out how difficult it is to block them.

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

Check out this fun science fair project idea to learn about seismic waves and how fast they travel during an earthquake.

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