The Chemistry students had their first in depth look at the mighty Periodic Table, that denizen of knowledge about matter, the stuff that makes up everything. We discussed metals and their place on the Table. We also talked about chemical changes, physical changes, elements, compounds, mixtures and pure substances. We looked at a bunch of examples of those things too.
The AP Biology students went to the library to try out a couple of simple assignments from Chapter 5 in their text. We also talked about enantiomers which are those weird isomers that are mirror images of one another and that subtle difference makes a HUGE difference in terms of biological effects. Check out thalidomide and you'll know.
