Large popsicle sticks
Small popsicle sticks
In the Making:
This is our the base of our catapult
This is our catapult almost finished
This is our final product with the "basket" part added
Problems we faced:
Our team faced the problem of the base not being sturdy enough. We also had trouble making holes in the popsicle sticks for the paper clips to go through. We compromised that problem by softening the popcicle stick with water and using scissors to poke a hole through.
The ball had potential energy when it was sitting on top of the catapult about to be shot. The catapult had mechanical energy when we actually built it. The ball had kinectic energy when it was flying through the air going towards the ground.
