I introduced energy to my students today. I mean, they’ve had energy all along, but I introduced the vocabulary of energy in science to them today. We also played with an electro-static generator (one of those large metal balls that emits an eletric field and when you touch it, it makes your hair stand up and gives you a shock), which was AWESOME! The kids all seemed to know that it would shock them, but watching them try and touch it was fun… and I would be lying if I didn’t say I turned up the power when a particularly annoying student went to try…
I also waited until a student did it in each class before I touched it myself… I mean who wants to get shocked? Not I.
