Day 13: Energy Experiments (Round 1)

Imag1454

College-prep students using carts and rubber bands to design their own qualitative energy experiments. The focus is "What factors determine the amount of energy stored in a moving cart? In a stretched rubber band?" In pre-lab, we brainstormed possible factors, then I assigned each group one cart factor and one rubber band factor to investigate (with some overlap among groups for consensus purposes).

I forgot how painful it can be watching students design their own experiments. I might even have them do it over again, but with more guidance from me.

(But that's OK, because now they'll be ready for the guidance, having experimented on their own first. Right? I'm thinking about Schwartz's "A Time for Telling.")
