Tomorrow in AP Biology, we will be working on our Enzyme Lab ... using catalase to breakdown hydrogen peroxide in different time intervals starting with 10 seconds and ending with a 240 second interval. We will calculate the rate of reaction between time intervals and discuss how we could expand this lab (inquiry). This lab includes a titration. For a pre-lab rundown on the lab see the Bozeman.

We will discuss again the importance of enzymes in living systems and how they lower EA ... activation energy.

The rest of the week, our top juniors and some seniors will miss class for the APES program ... an opportunity for students (over 30 of them) to win a total of 2100 dollars ... on average that figures out to about 20 dollars a day for each student which is about $3.50 an hour ... really ... hardly worth it IMO. I and other teachers will carry on in their absence with the students we have remaining in class. Each time you miss a block class you miss about 2% of the total content of the class.
