Hardy-Weinberg - Math Meets Biology

I heard a science teacher say that all biologists think they're chemists, all chemists think they're mathematicians, and all mathematicians think they're God.  Well, today in Honors Biology, we skipped over the chemists and went straight for math.  Though, after a day of wrestling with their first exposure to solving Hardy-Weinberg equations, only a few students felt like deity.

Here's a shot of the whiteboard.

I also had my first observation by my college supervisor.  He came 4th period, so I had a chance to practice beforehand.  Overall, the observation went well.  There were a few items related to small classroom management strategies that I need to improve.  The timing of handing out worksheets was one of the issues mentioned.  I began the lesson and forgot to hand out the papers during a down period when students were solving a bit of math.  Overall it didn't hurt the entire lesson, but it did create an awkward lag in the lesson as I hurriedly passed out papers.  His second suggestion was that I not turn my back to the class when I write on the board.  This one may take a while to fix; I already have trouble writing on a whiteboard while facing the board directly.  Changing my stance may degrade my whiteboard-manship.  But, it'll be important to learn this skill so I'll work on it.

Tomorrow we'll finish up the Hardy-Weinberg equations and watch a short clip of genetic drift in action.
