Learn about how the Doppler effect explains the change in pitch as a sound source moves in relation to you with this activity. This activity has the students making their own Doppler ball.

The Doppler Effect is used to determine the size of the universe as well as predict the weather. Watch this video to get an idea of just what is happening when we experience this scientific phenomenon. [1 min, 03 sec]

Review key terms and skills for the Doppler effect, including how to interpret wavefront diagrams.

[Free Registration/Login may be required to access all resource tools.] Discusses what the Doppler Effect is and how it occurs.

Students will see and hear demonstrations of the Doppler Effect and then make an advertisement for a rock and roll band called "The Doppler Effect".

A simulation of the Doppler Effect, where a change in wave frequency can be observed from the reference frame of the wave source, an observer, or the medium.

In this module, students investigate the properties and behavior of different types of waves.

In this tutorial, Bill Nye explains how you can use a piece of string and a noisemaker to demonstrate the doppler effect.

[Free Registration/Login may be required to access all resource tools.] Recognize how redshift suggests the universe is expanding.

[Free Registration/Login may be required to access all resource tools.] Definition of wave frequency and how it is related to the energy of a wave.

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.

Try this at-home science experiment to learn about the Doppler Effect.

While some of the pages on this site have yet to be filled, the pages that are complete are comprehensive. For example, pages on friction, heat, and the Doppler effect are illustrated and explain relevant formulas. A biography page...

This journey will help you solve big questions about the universe. You will be able to see beyond human capabilities and will learn what scientists are discovering.
