The AP Biology students completed Part 2 of the practice multiple choice AP Biology Exam today. A total of 69 questions. A good goal is to get 40 correct. That is a good starting point. The students that have the highest scores on part one and part two will get awesome prizes tomorrow!
The Chemistry students finished the activity on the decay series of Uranium-238. We also graphed the decay series and included another series directly onto the graph. We also began a good discussion of half-life and did a couple of half-life problems.
