The Chemistry students had a group review activity where they had several problems involving isotopes, molar mass and converting grams to moles, mole to grams, atoms to moles and moles to atoms. Everyone did great. We're gonna have a quiz on this material on Friday. Yay!!
The AP Biology students began Activity B of the Mitosis and Meiosis Lab. This involved observing and counting the different phases of mitosis within onion root tip cells. Ahh..... the excitement of discovery was palpable in class. Once the students have made their counts and we compile class data, we can make estimates in how long each phase takes during the cell cycle. We'll do this tomorrow.
