Day 71

ADVISORY DAY!!!!!!!!! HURRAY!!!!!!!!!!!
The AP Biology students got their first exposure to the chi-square test which doesn't require a shot of penicillin. The chi-squared test is a way to test the validity of the data collected in the Fly Lab. Think of it this way. If you flip a coin 100 times, you would expect to have 50 heads and 50 tails. But what if you got 67 heads and 33 tails? Is that because of chance or is the coin screwed up? The chi-squared test allows you to make that determination.
The Biology students began an activity on chromosomal mutations.  There are some horrific ones, to be sure. The students were given a chromosomal map of an individual.  It is up to them to determine what type of disorder, if any, the individual has.
The Chemistry students got a crash course in rocket science which is probably a bad way to teach rocket science.  With the crashing and all. Anywho, we will use our considerable knowledge of stoichiometry to create the optimal mix of gases to launch a rocket.

December already!?! Next thing you know, you'll be 50.
The AP Biology students worked on the Fly Lab, completing most of the analysis questions regarding their data that the different groups gathered yesterday.  Tomorrow, we'll talk about the ol' chi-squared test.
The Biology students took the Protein Synthesis Quiz.  About half the students got a perfect score. The other half didn't because they forgot that DNA does not contain uracil.  IT HAS THYMINE!!!
The Chemistry students continued the work on the Stoichiometry Lab. We worked on some practice problems as well.
