Lessons activity is in
  • 8 regular popsicle sticks
  • saw
  • 2 jumbo popsicle sticks
  • 3 elastic bands
  • tin foil

Use a saw to make a notch on either side of both jumbo popsicle sticks, about 2cm from one end.

Stack up 8 regular popsicles sticks, insert one jumbo popsicle stick between the two at one end of the stack. Wrap the stack tightly with elastic bands on each side.
Lay the second jumbo popsicle stick over the top of the stack, and wrap an elastic band around both jumbo sticks, making sure that it rests in the notches.

Make tin foil balls to fire with the catapult. They will go about 1m into the air.
