We started the class with a warmup. I asked students to describe the connections between facilitated diffusion, mitochondria and carbohydrates. Additionally there was challenge question asking you to connect chloroplast, protein and cleavage furrow. We discussed the possible answers to these two questions, but of course there are multiple ways that these terms can be connected.
Next we went through last night's homework to see if there were any questions. This led to an activity that simulated the stages of mitosis using paper strips (chromosomes), paper clips (centromeres) and chalk (to draw spindle and membranes). This activity is actually Lab 3A of the 12 AP Biology labs. This activity was followed with a brief explanation of binary fission in bacteria.
HOMEWORK:
The OPTIONAL homework assignment is to familiarize yourself with what cancer is and how it relates to cell division. One of the best sites for this is a site we will be using in class entitled "Inside Cancer." From here you can select any of the slide shows in Hallmarks of Cancer, Causes and Prevention, Diagnosis and Treatment or Pathways to Cancer. There is no required homework.
