Today was a tricky day. Between yesterday’s snowstorm and this morning’s wind chill warning, a lot of the districts around here closed. We stayed open, but announced that weather-related absences would be excused (they normally aren’t). I ended up with around half my students gone each hour and had to adjust on the fly.

AP Physics 1: Pendulum Whiteboarding

We had a quiz on deck for today, but I was concerned about how many students would need to make it up. Instead, we spent today whiteboarding some conceptual questions about pendulums.

Physics: Projectile Whiteboarding

Students whiteboarded some problems sketching and interpreting velocity vs. time graphs for projectiles. I also got out the demo to show an object dropped and a horizontal projectile hit the ground simultaneously.

Chemistry Essentials: Phase Change Whiteboarding

We’d planned an in-class retake of the phase change quiz today, since last week’s weather meant we took the original late and some students really struggled as a result, so it seems to be a quiz destined for weather interference. We went ahead with giving the in-class retake today, but also spent some time whiteboarding practice bar charts to review beforehand.
