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

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.

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

Find out whether matching resonant frequencies can cause objects to shatter.

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?

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.

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.

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

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.
