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.

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.

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