The Chemistry students continued with the measurement lab. I went over MASS and VOLUME. I capitalized those words because of their intrinsic importance and I'm pretty sure I misused instrinsic just then. So we made a bunch more measurements and there we are. Oh, I included the Power Point thing at the bottom of this entry.
The AP Biology students did the actual physical part of Part B of the Osmosis and Diffusion Lab. The students made a lot of dialysis bags of varying sucrose concentration and put them in 100% water and checked out what happened. What happened was that those bags better have gained weight. I bet they did.
