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 Effect
Here comes the sound. After watching a couple videos demonstrating and explaining the Doppler Effect, learners develop their own understanding of the phenomenon. Scholars draw a sound wave and observe how the perception of the wave...
McGraw Hill
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...

Sound
Beautiful music doesn't just write itself, but if you ever feel bad about procrastinating, remember that Mozart wrote the overture to Don Giovanni the morning it premiered. Introduce young scientists to the elements of sound including...

The Doppler Effect Lab
In this Doppler effect worksheet, middle schoolers read information about the Doppler effect. Students answer questions as it relates to the pitch and wavelengths of a demonstration simulates what happens with the Doppler Effect.
LABScI
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...
Curated OER
Doppler Weather Radar
In this Doppler weather radar worksheet, students read about radar and Doppler weather radar and answer three questions about how they work and the Doppler effect.

Computer Interfacing: Frequency Measurement - The Doppler Effect
Students explore the Dollper effect by finding the frequency and velocity of sound. In this velocity lesson, students determine the impulse during a collision by using their data and a software program.

Waves, Sound, and Light
Ninth graders explain waves in terms of energy transfer and describe their basic types and characteristics. They solve mathematical problems involving wavelength and frequency. Students conduct experiments in reflection and refraction.

Beating the Motion Sensor
I bet I can cross the room without having the lights come on. Class members set up an experiment in which they try to determine what materials will mask motion detected by a sensor. Groups predict how materials will interact with light,...

Physics 210 - Frequency
In this frequency worksheet, students use the speed of sound to determine the frequency in which sounds are heard in 5 different word problems.

Sound Waves; vocabulary review
In this science worksheet, learners locate 28 words in a word search. The focus of the word search is vocabulary connected to the study of sound waves.

The Speed of Galaxy Q2125-431
In this speed of a galaxy learning exercise, students use a given equation for the speed of an object and they use the spectral lines for Hydrogen Alpha and Beta from the Seyfert galaxy to answer 6 questions. They determine the observed...

College Physics for AP® Courses
Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains multiple...

Reading the Waves
Young scholars view video segments which reveal the parts of sound and what factors control sound. The viewing and post-viewing activities serve to reinforce the video segments using worksheets and hands-out experiments.

Determining Red-Shift in a Receding Star
Young scholars practice manipulating algebra formulas with more than one variable. They examine the topics of velocity, wavelength and frequency. They determine the amount of red-shift in a receding star.
