Vibration and Sound

Learners twang a ruler, stretch rubber bands and watch rice jump on a plastic-wrap drum to gather evidence that vibrating materials make sound and that sound can make materials vibrate. A string simulation shows how shorter or tighter strings vibrate faster and sound higher, and a harder pluck makes a louder sound.

What learners will discover

  • Use evidence to explain that sound is made when something vibrates (moves quickly back and forth).
  • Use evidence to show that sound can make materials vibrate.
  • Compare how the length, tightness and pluck of a string change its vibration and sound (higher or lower, louder or softer).
