The Chemistry students began an activity using cups, 100 pennies and graph paper. No, they weren't making ice skating costumes. We were defining half-life, the time it takes for 1/2 a radioactive sample to decay. We will continue working on this next Tuesday.
The AP Biology students had their second look at the AP Biology Exam which isn't easy. We did some multiple choice questions and some mathematical stuff too with the grid-in questions. We will continue this next Tuesday.
