Now this is a very good demonstration of the Doppler Effect and how it works. A police car with its siren blazing is filmed as it travels closer and then farther away. The effect is explained through text and an illustration. Good video.
Students evaluate the Doppler effect. In this Doppler activity, students investigate Doppler radars and sound waves. Students log on to Second Life and complete Mr. Doppler's Wild Ride.
In this Doppler effect worksheet, students 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.
The Doppler effect is demonstrated in your physical science class with the included instructions. The directions call for a watch, which most kids do not wear, so consider gathering a class set of stopwatches to set alarms off for the required sound. Because of the nature of the activity, you will only want to carry it out with mature individuals.
Students use an ordinary toy to reveal the Doppler effect. The connection is also made to moving cars, and to the shifting of the lines in the absorption or emission spectrum when the distance between a star and Earth is increasing or decreasing.
Eleventh graders investigate the Doppler effect as it relates to relative motion on frequency of a sound source. In this Doppler effect lesson, 11th graders assemble buzzer-battery devices, look for changes or lack of pitch in the sound waves emitted by the buzzers, and collect data. Students solve the Doppler effect problem and discuss details of their work and thought process.
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.
Students explore the Dollper effect by finding the frequency and velocity of sound. In this velocity lesson plan, students determine the impulse during a collision by using their data and a software program.
The history of our understanding of the center of the universe is explored through this film. The ideas of Aristotle, Copernicus, Bruno, Descartes, and Herschel are included, as well as the new discoveries that have helped the theories evolve. Concepts mentioned include the Doppler effect, red shift, blue shift, and the big bang theory. Narration by a teenaged girl and colorful animations make this engaging even for the most distracted earth scientists in your class! Follow the video by discussing the questions provided on the website.
In this Doppler Effect activity, students answer questions about the movement of stars and the reason we see differences in the color of the stars resulting in a red shift or a blue shift.
Twelfth graders stretch and shake a helical coiled spring rapidly with an up and down motion in order to generate wave pulses. They observe the patterns of movement produced in the spring. They read text and watch a video "The Nature of Waves."
An incredibly colorful PowerPoint presents all the facts and definitions about waves that you could need for beginning physical scientists. There are several useful links to online animations of wave action. This may have been produced by a student, but it is still a nice piece that states the important information clearly and will definitely keep the attention of your class. You may want to prepare a question sheet with a sequence related directly to this slide show.
This physics resource provides questions as well as information about sound, including frequency, oscillation, the Doppler shift, and more. There are 5 short answer questions that are mostly based on frequency. After the questions, there are 5 pages of information with examples. These pages could be used as notes or reference pages. Answers and explanations are included.
In this physics 240:26 worksheet, students determine the frequency of the waves in a word problem. Students calculate the speed of the wavelength. Students explain how a sonic boom occurs from the Doppler Shift.
Tenth graders explore the structure and content of galaxies. Through discussion, lab, and hands-on activities, they discover the general structure of the three types of galaxies as well as the effect they have on the structure and function of the universe. Two lessons are included.
Students research the constellations and discuss their findings. Then they construct their own maps of the galaxy using paper, black paint, aluminum foil, etc. They make a 3-D map of their chosen constellation.
Twelfth graders investigate the relationship between the apparent frequency of sound waves detected (perceived) and the relative motion between the detector and the source of the sound waves.
Students 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.
