Showing Results for monsters around the world

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.

Demonstrate how we are able to locate sounds, echolocation. Have a blindfolded subject locate you by the sound of your clapping.

In this science fair experiment, students learn about the scientific principles behind Doppler ultrasound.

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.

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

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.

This science fair project idea produces sounds by creating vibrations using different objects.

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.

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.

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

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