What causes the speaker to vibrate?

• The sound makes it vibrate.

• The speaker needs a force such as being plugged in or turned on to cause vibration.

When the speaker vibrates, why do the air particles move?

• The air particles move because the speaker pushes on the air particles.

• The air particles move because of the sound.

If the sound had a low pitch, how would the particles move?

• The particles would vibrate back and forth farther from the speaker.

• The particles would vibrate back and forth closer to the speaker.

• The particles would vibrate back and forth slower.

• The particles would vibrate back and forth faster.

Why does the sound detector vibrate?

• It vibrates because the speaker is playing sound.

• It vibrates because the air molecules are pushing on the sound detector.
