This afternoon we spent the whole afternoon in the heart working with Class 8. There were 4 different experiments:
- create a wind instrument using straws
- create a guitar using boxes and elastic bands
- What moves faster, light or sound?
During this experiment we filled a balloon full of flour. We then popped the balloon and look at whether the flour hit the ground first, or whether we heard the sound first. We realised that light moves faster than sound as we saw the flour before we heard the sounds.
- Can you prove that vibrations exist?
