The purpose of this science fair project is to build a basic radio.

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.

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

This classic children's game demonstrates how sound travels through air vs. through a solid.

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

This science fair project idea demonstrates sonar mapping of the ocean floor.

Determine the relationship between the speed of a sound and the temperature of the air it passes through.

Look for a correlation between temperature and the intensity of cricket chirping. Measure ambient temperature and sound intensity in decibels.

Find a mathematical relationship between the intensity of a sound wave and distance from the sound source. Use a pedometer and a sound level meter.

The objective of this experiment is to identify common materials that absorb sound waves with the greatest efficiency.
