Stellar Fingerprints and Doppler Red Shifts
Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format lesson plan.

The Doppler Effect
In 1842, Christian Doppler proposed a theory relating the change of wavelengths based on motion. Young scholars observe the Doppler Effect on a small scale in a ball, on a larger scale from a car, and on the largest scale studying the...

Doppler Shift Interactive
Ever wonder why a siren sounds different when it's coming toward you than when it's going away from you? It all depends on the motion of the sound waves! The interactive activity demonstrates how the Doppler effect impacts the motion of...

Acoustics: The Sound Lab
If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels. Whole...
