In outer space there is utter silence. There are no sounds of traffic jams or thunderstorms or crashing waves. No buzzing bees or babies crying. Just silence. In this experiment, you will discover why empty space is void of sound.

This resource explores how vibrating objects produce sound waves. The site contains information and an animation.

[Free Registration/Login may be required to access all resource tools.] Students investigate and analyze characteristics of waves, including velocity, and calculate the relationship between wave speed, frequency, and wavelength.

[Free Registration/Login may be required to access all resource tools.] This guide gives a detailed overview of mechanical waves and the characteristics of waves. Covers wave behavior, including types of interference, resonance, and the...

Introduce some activities that introduce students to the physics of sound. They will also learn how various instruments produce sound. Included are downloadable pdf worksheets and answer sheets to use.

Kids learn more about the science and physics of sound. Pitch, acoustics, and the doppler effect. How the frequency of the sound wave affects the pitch we hear.

All waves will reflect and refract in the right circumstances. The reflection and refraction of light explain how people see images, color and even optical illusions. This tutorial discusses each concept and presents an experiment to try...

In this physics science fair project, the student will use common materials to play back sound from a vinyl record album. The student will investigate what kinds of materials produce the best sound. The Science Buddies project ideas are...

Great activity for primary and intermediate students to learn why objects make noise. This can be organized in stations or in groups of students.

[Free Registration/Login may be required to access all resource tools.] Students investigate behaviors of waves, and explore the Doppler effect phenomenon.

This high school physics lesson focuses on the application of the Doppler effect to sound. Discusses what the Doppler effect is, offers examples of its occurrence, and explains what shock waves and sonic boom are.
