The Chemistry students got their first look at electron dot diagrams. I'm pretty sure that most students realized that creating electron dot diagrams for atoms is pretty easy as long as you have a Periodic Table handy. Tomorrow, Lewis Dot Structures for molecules.
The AP Biology students did Part B of the Photosynthesis Lab. That means DPIP, chloroplasts and the spectrophotometer. It went pretty good but, as usual, the chloroplasts were photosynthesizing like crazy and the DPIP got reduced real fast. But never again.
