Rube Goldberg-like contraptionsI was studying the energy transformations and forms of energy in the game "Mouse trap"

this toy made me wonder - does a lever have potential energy, just by being a lever?

  Dear Linda,

  Have you tried the "Cat-traption" on the Energy site (http://www.learner.org/workshops/energy/cattraption/)? It's an animated version of the Rube Goldberg-like contraption used in demonstrations on the videos. There's also a Web highlight about it, with a challenge, at http://www.learner.org/workshops/energy/workshop3/icon1.html .

  I'd love to know if that's useful to you, especially since you find the Rube Goldberg contraptions helpful to your teaching already.

    Hello again! I like the Mouse Trap idea for my simple machines unit. I use pictures of the Rube Goldberg contraptions to identify simple machines and energy transfer. The kids love the contraptions. I found the pics on a Rube Goldberg internet web site.
