In the lab activity, you will examine sound waves as they are emitted from a moving source. Predict what will happen to the sound waves when the sound source is in motion. Record your prediction (hypothesis) as an “if then” statement. (For example: If you select the GO button, then the train will move)

The idea is you do a hypothesis so that you can compare it with experiment results. I suggest you do it yourself because if you give out the right answer (which is quite nonintuitive) the teacher will know you googled it. Nevertheless if you want to get ahead of yourself just for the sake of knowing, I suggest you investigate the doppler effect.

as a sound source gets closer, both the volume and the pitch of the sound increased. Then, as the sound source passed by you, both the volume and the pitch of the sound decreased. Hope this helps!
