Thurs-Day 1
Bio 3/6 - worked on our muscle projects for most of the two periods and discussed some of the scientific method questions that came up: a "control group" IS a comparison group; ANY comparison group that has IDENTICAL factors/setup as the experimental group EXCEPT for ONE variable. The variable that is different can be a placebo OR a different amount or TYPE of whatever is being varied (in this case, the time of each part of the exercise).
AP Chem- we continued to develop our chart (AX4, AX3E, etc.) using VSEPR, valence shell electron pair repulsion theory and valence bond theory to determing the electronic geometry and the respective orbital hybridization required for such a geometry.
