The Chemistry students got their first look at the meaning of molarity which we all know refers to the concentration of solutions. A 1.0 Molar (M) solution of salt water is said to have 1 mole of salt dissolved per liter of solution. We also reviewed titration, the technique used to determine the concentration of an acid or base.
The AP Biology students got their first look at the Hardy-Weinberg equation, a way to predict gene frequencies from one generation to the next, if the population is in Hardy-Weinberg equilibrium. We also reviewed the upcoming lab on Population Genetics.
