The chemistry students continued the activity of constructing their own Periodic Table. We will work on this tomorrow as I have a meeting on campus but will not be in class. We'll talk about a college on Thursday.
The AP Biology students were introduced to meiosis, the process by which the chromosome number of a cell is effectively divided in 2, thereby guaranteeing that sperm and eggs (gametes) will have 1/2 the "normal" chromosome number. Humans have 46 chromosomes in every cell of their bodies with notable exceptions being sperm and egg. They have 23. If they didn't, children born in the next generation would have 92 chromosomes and a myriad of physical problems one could only describe as "freaky". The Mitosis and Meiosis Lab is due at the beginning of class on Thursday.
