The Chemistry students we introduced to the concept of concentration and molarity. We also did a bunch of calculations using this equation: Molarity = moles/liters really easy stuff (at least it should be). We also started a worksheet with several practice calculations. This will be the second thing turned in this semester.
The AP Biology students were introduced to the good ol' Hardy-Weinberg equation which can be used to predict a bunch of stuff about populations that happen to be in Hardy-Weinberg equilibrium. We did a bunch of practice problems today too.
