This science fair project demonstrates the principles of reflection through simple experiments involving mirrors and light.

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

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

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.

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

This science project examines the history of earthquakes and what we can do to prevent future disasters.

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

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

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

How fast does light travel in different mediums? Kids conduct a cool refraction experiment in materials like water and air for this science fair project.
