## Reflection: Adaptive Technology The Doppler Effect - Section 1: Context & Equipment Needs

Even though Doppler Balls aren't expensive, they might not be available when needed for a lesson. The great thing with technology is that there are so many options out there to supplement instruction with the click of a mouse. A video of a passing fire engine is something that can easily show the Doppler Effect in the real world. Also, this video uses a car horn, and is another good demonstration of the Doppler Effect.

And, if showing a video isn't an option, students always revel in the opportunity for a field trip: even if it's just down to the parking lot to watch the principal drive by and honk her horn!

What if I don't have a Doppler Ball?

# The Doppler Effect

Unit 8: Sound Waves
Lesson 2 of 6

## Big Idea: Students continue to roll through this unit of sound when the see a Doppler Ball and define the Doppler effect in terms of frequency and movement of the observer.

###### Wave Hello
High School Physics » Waves
Big Idea: The velocity of a wave can be determined by multiplying the wavelength times the frequency or by dividing the distance the wave travels by the time it takes to travel a that distance.
