Instructions for your mad marble experiment:
1. Build a small building with the blocks and attach the ramp.
2. Choose one of the marbles and send it down the ramp 10 times.
3. Put a sticker on where it ended each time.
4. Repeat with a different sized marble (10 times).
5. Now have a guess where the third marble will finish. Were you right? What did you base your prediction on?
6. Repeat the experiment by changing something- e.g. change the slope of the ramp or the ground it is on.
7. Use a computer and try this exercise on
forces.
