In the Doppler Football Demonstration Kit for physical science and physics, tackling the Doppler effect is a snap. Drive home the concepts of sound wavelength and frequency with an audible tone emitted from a foam football.

Product Details

Tackling the Doppler effect is a snap with this fun demonstration. Score extra points with your students as you drive home the concepts of sound wavelength and frequency with an audible tone emitted from a foam football. After connecting the buzzer to a 9-V battery, simply place the buzzer inside the specially prepared football, seal and throw! The receiver hears a higher pitch and the passer hears a lower pitch compared to the actual tone emitted by the buzzer.

Includes modified 6" foam football, buzzer, battery clip with alligator leads and tape. Teacher demonstration notes include complete instructions, background information and reproducible student worksheet with answers to all questions. Requires 9-volt battery, not included.

Performance Expectations

MS-PS4-1. Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
HS-PS4-1. Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.
