Simple Machines Inquiry Term 2

We all had another go at creating our catapults. First we talked as a class about what worked well and what didn't work so well. We talked about what changes we could or should make to make our catapult better.

We talked about:

- More force
- Longer lever
- Lifting it higher
- Lifting the Fulcrum
- Using a lighter thing to throw
- making sure it doesn't move ( use rubber bands or blue-tack)

Here is a video of our competition!!
