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

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

Find out the differences (if any) in the frequencies of voices produced from a computer, from a phone, and directly coming out of the voice box of a human.

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?

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

Explore the wave-particle duality of light! Learn how light can behave as both a wave and a particle in this cool physics science fair project idea for kids.

In this cool science fair project, kids apply basic algebra to learn how to make a PVC pipe instrument while exploring concepts like frequency and resonance.

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

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.

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

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

What is the Doppler Effect, or the Doppler Shift? The purpose of this science fair project is to determine how distance impacts the Doppler Effect.

The goal of this science fair project is to evaluate the effect of heat on sound wave frequency.
