Day 149: Final Project, Problems, & Whiteboarding

AP Physics: Final Project

Students continued refining their proposals for the final project. Lots of students have ideas I’m really excited to see. A few students are working on ideas where it may be interesting to look at dissipated energy, so we got out the infrared camera to play a little. It turns out some glasses block a lot of IR.

Physics: Problems

Students worked on some sound wave problems. Things seem to be clicking for most students.

Chemistry Essentials: Whiteboarding

We spent some time talking about the observations students made during yesterday’s lab and drawing explicit connections to the equation for the chemical reaction. My students don’t have a great sense for what certain chemicals look like, so it ended up being more teacher directed than I’d like. Students also weren’t sure when a chemical will show up as a gas, since I’ve dropped the subscript g in order to simplify the equations we’re looking at, but I’m not sure that is a useful simplification.

After the discussion (or, more accurately, lecture with student responses), student whiteboarded some limiting reactant problems. The students who were engaged made some good progress.

This student asked me if I could write the symbols for sodium hydride and bromine oxide
