The AP Biology students continued their discussion of evolution and natural selection today. We also watched a little of a film on the advantages and necessity of sexual reproduction. Super interesting discussion ensued.
The Biology students saw how gel electrophoresis can separate fragments of DNA and, in doing this, how we can use this separation to identify unique samples of DNA. Do that, and you can identify an individual. And you can use this to do a bunch of stuff.
The Chemistry students began the Acid and Base Lab today. During this lab, the students will explore the properties of acids and bases. We will not, contrary to rumor, capture an alien whose blood is an acid.
