stem

We looked at rice on a drum. it did  big vibrations wen I hit it hard.

Me and James made an amplifier. It made Miss Stapleton’s phone a bit louder.

  1. Hi Owen and James,
    The amplifier you made looks like it would be effective – well done! And with your drum you proved that vibrations are bigger when sound is louder. Great work!
