Physics: Joly Photometer

With over half of my students gone for another AP test today, I ended up giving them the hour to finish yesterday’s assignment with the Joly Photometer Direct Measurement Video. I’ll have a lot of students gone tomorrow for AP calc, so I need to figure out how I want to handle discussing the results of this and Monday’s lab.

Chemistry: Energy in Reactions

We talked about of yesterday’s lab, then took a look at energy changes in chemical reactions to start thinking about why some of the things we tried change the reaction rate.
