In AP Biology today after a three day weekend for students, we started with a genetics review. Using many M&Ms, we generated a hypothesis that there were equal amounts of each color of M&Ms in each package for a 1:1:1:1:1:1 ration. After generating data, we did the Chi Square analysis and rejected the null hypothesis. Second block then generated a second hypothesis which 2:2:2:1:1:1 ration which was close. The actual percentage are on the M&M website ....
Most current information shows that in each bag of M&M's, the percentage's of each color are:
24% blue, 14% brown, 16% green, 20% orange, 13% red, and 14% yellow ... so, our second hypothesis was close. More Chi Square practice problems later ...
On Thursday, we will review Replication, Translation, and Transcription, mutations of DNA and start our F1 crosses for our Drosophila lab. We will be using sepia and apterous mutants in this lab.
In Computer programming, we are working on graphics problems and have started with examples of animation.
Tomorrow in Selected Topics of Science we will be finishing our structure problem in second block and working on frequency and period calculation in first block.
Next Monday, we will be on a Wednesday/Friday day instead of our 8 period day.
Next week, we will be in school on Monday and Tuesday before taking off for Thanksgiving vacation. After that, three weeks until Christmas vacation and the end of first semester.
