Tic Tac Bounce

AKA Inventing a New Flavor of Energy Storage When we start the energy unit, we usually pick up 4 flavors (kinetic, gravitational, spring, and thermal) and note that we will recognize and name other ways of storing energy when we see them. That happens pretty immediately when we do pie charts. We run into a problem pretty… Read More Tic Tac Bounce

What if we didn’t finish all of the questions?

My Physics 10 (a trimester-long class exploring E&M topics for 10th graders who haven’t yet studied mechanics) was wrapping up some extensions to an electrophorus activity. They were already pros at explaining and predicting electrostatic phenomena, but this activity gave them yet another way to test out their thinking, practice their charge diagrams, and add depth and subtlety… Read More What if we didn’t finish all of the questions?

Drawing accelerated position-time graphs

During our PLC chat this week, we talked at one point about how long it takes for students to become completely consistent in drawing motion graphs. My experience has been that students become confident relatively quickly in drawing the velocity-vs-time graphs (having switched their brain into thinking through v-t graphs), but still sometimes struggle to draw… Read More Drawing accelerated position-time graphs
