The Chemistry students continued practicing a bunch of stoichiometry problems by, well, practicing a bunch of stoichiometry problems. I even colored-coded an example on the white board which I thought was a pretty good idea. Of course, if someone still doesn't know how to figure out molar masses, that's a problem.
The AP Biology students finished up the discussion of DNA by talking about Okazaki fragments, leading and lagging strands and replication forks. The Chapter 16 Reading Guide is due tomorrow BTW. I think we may start the Gel Electrophoresis Lab tomorrow too.
