Science - Sound Vibration investigation.

As part of our science topic (sound) we have been learning that sounds are made by vibrations. Of course we had to make sure that this was definitely the case and conduct some fun experiment! We started by placing our fingers on our throats while we talked. Then we tried out 4 different experiments:

  1. Talk in to a balloon. What can you feel?
  2. Bang a drum with sugar on it. What happens to the sugar and why?
  3. Hit a tuning fork off a table then put it in some water. What happens to the water and why?
  4. Hang a spoon from your ear and hit it off something. What can you hear? How can you hear it?

Even though we might look a little crazy carrying out these investigations, they really helped our understanding of vibrations.
