Rubber Cart


In this games, kids create a car powered by a stretched rubber band



Materials :
  • Cardboard
  • Masking Tape
  • Bottle Cap
  • Straw
  • Sausage Stick
  • Scissor
  • Paper Cup
  • Pebbles
  • Rubber

Challenges:


  1. Let them choose how many rubber bands they want to use.
  2. Give them fewer rubber bands than they ask for. Add some weight to the launcher.
  3. Letting them figure out how it works on their own can be a challenge.

Questions to be asked:


  1. What else could we use instead of a rubber band to make the car go? Why not use thread?
  2. What changes when we use a longer or shorter rubber band?
  3. How can we make our rubber band car go faster?
  4. How far do you think your rubber band car can travel when you wind it up really tight?
