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

Whiteboard Face-Off

Next up in whiteboarding modes: The Whiteboard Face-Off (aka Board Meetings*). When we have a Face-Off, every group is whiteboarding the same problem. No one presents. Instead, we sit on the tables (bringing in our circle and keeping people from just doing more work in the packet and skipping the discussion) and all share our… Read More Whiteboard Face-Off

Building the Constant Velocity Model

Here’s a binder. And the handshake. [As they walk in, I’m handing out their binders (with materials, labeled dividers, spare graph paper, their names on the sides) and shaking their hands as we make the transaction. I’ve seen some discussion in various places online about the appropriateness of shaking students’ hands on the first day of school.… Read More Building the Constant Velocity Model
