I was out of the classroom today while the AP Physics 2 students completed the electrostatics unit exam. I dug through my photos and found one of a whiteboard from a few days ago that I didn’t use in that day’s post. It is an electrostatics conservation of energy problem. The group that prepared this whiteboard included an energy LOL diagram. I’m thrilled how that particular representation helps students organize their knowledge for conservation of energy problems. I can’t believe it took me so long to integrate them into my teaching!
