The Chemistry students were re-introduced to the idea of stoichiometry as a vehicle to predict the mass of a product produced in a chemical reaction. It was slow going but we made it through for the most part. Some students' math skills are, shall we say, not good. We will work on this over the next 3 days.
The AP Biology students began a 2 day look at DNA and the replication thereof which means the replication of DNA which means the copying of DNA. We did some structural stuff too.
