The Doppler Effect

The Doppler Effect | Science Fair Projects | STEM Projects
Have you ever noticed that sound changes when you move? This phenomenon is called the Doppler Effect. It's a fascinating way to explore how sound is affected by motion.


The hypothesis is that sound changes when you move.

Method & Materials

You will play a song on the computer or phone, stand still and listen to the song, and then move fast while listening to the song.
You will need a computer or phone to play the song.


The Doppler Effect is an interesting way to explore how sound is affected by motion. When you move fast, the song will sound different than when you stand still.

Why do this project?

This science project is unique because it allows you to explore the Doppler Effect in a hands-on way.

Also Consider

Experiment variations to consider include playing the song at different speeds and changing the distance between you and the source of the sound.
