Challanges
- Let them choose how many rubber bands they want to use.
- Give them fewer rubber bands than they ask for. Add some weight to the launcher.
- Letting them figure out how it works on their own can be a challenge.
Questions to be asked
- What else could we use instead of a rubber band to make the car go? Why not use thread?
- What changes when we use a longer or shorter rubber band?
- How can we make our rubber band car go faster?
- How far do you think your rubber band car can travel when you wind it up really tight?
