## Reflection: Adjustments to Practice Observations On The Doppler Effect - Section 3: Students Create Explanation for the Doppler Effect

The Old Doppler Introduction worksheet I had students measure the distance between the circles and apply the wave formula to calculate the frequency. I had them do this because I thought that applying math to the situation would help students understand it. However, this is not the case. Though Student Work - Doppler Intro was usually accurate in the numbers produced, this did not help students work through an explanation of why the Doppler Effect occurs. I changed the sheet to focus on the primary concepts involved in the Doppler Effect.

# Observations On The Doppler Effect

Unit 5: Waves
Lesson 8 of 15

## Big Idea: The Doppler effect is the apparent change in a wave's frequency due to the motion of the wave source or the observer.
