on hands on acitvities, or teacher demonstrations to show potential and kinetic energy? I posted on the science board but didn't get any replies. I can't seem to find anything that would work in the classroom (or even outside in the courtyard). I posted here earlier too and did get a couple of good replies, but I would like some more ideas if anyone has any.

Thanks!

We got long tubes from Home Depot. They were the styrofoam tubes like you use to cover your pipes so they don't freeze. We cut them down one side so they were open. Then we used them to make roller coasters. The kids would use marbles and make them go up and down the hills. This showed potential (when they were stopped at the top of a hill) and kinetic (when they were moving) energy.
