The chemistry students did some work on the explosion lab. Question: what is the ratio of hydrogen to oxygen gas that produces the most efficient explosion and, thus, the loudest explosion? The students got in groups and worked through some problems that, hopefully, led them to the correct answer. Certainly, we will see if that is the case on Monday.
The AP Biology students had a look at the short answer questions from last year's AP Biology Exam. We went over, in some detail, a couple of the questions: one of the lengthy ones and one of the questions that requires just a few sentences to answer. The exam is tough but all of my students are capable of passing if they put in the seat time!
