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

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.

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

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

This experiment will explore how mallets of various materials and weight create sonic tones of varying lengths.

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

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

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.
