Day 156: Base Sliding & Synthesis Day

Today is Tartan’s Relay for Life and one of my classes got visited by the infamous purple toilet. Note the Canadian bill donated by one of my students.

AP Physics: Base Sliding

Students are wrapping up data collection and analysis for their final projects. I’ve got two students looking at the physics of sliding into a base to try and answer whether feet first or head first is better. They’re in different hours, so I’m not too worried about the repetition, but they are also looking at some different perspectives. One is looking at angular momentum as the player moves from running to sliding while the other is focusing on the actual slide. Its actually a little too bad they are in separate hours since it could be fun to have them compare notes.

Earth Science: Synthesis Day

I feel like this unit has been pretty disjointed and students are not making connections between volcanoes, mountains, folds, faults, and plate tectonics. I had them work through some conceptual questions today to explicitly draw connections between those ideas, which illuminated some specific areas I need to revise in this unit. For example, one of the questions asked students to determine whether mountains or volcanoes are more likely to have folds, and it came out that a lot of students don’t have a mental model for how a fold forms.
