Yes, 6th grade. Small models to show potential and Kenetic energy. What would you like to know?

I was wondering what kind of supplies you used?

Popsicle sticks, masking tape, rubber bands and a plastic tablespoon scoop.

Kids did some research online and some came up with this model. www.stormthecastle.com/c...

It worked fantastic.
