The discussion on circuits was very helpful. Yes, the voltage decreases as more bulbs are hooked in series, making the bulbs all dimmer but the same brightness. When bulbs are hooked in parallel, it does not decrease the voltage and both bulbs burn brightly.

I liked the lab on enzyme activity in the afternoon, so much so that I plan to use it in my classroom. I answered the questions with my lab partners and turned them in with my graphs on Thursday. I have enjoyed all of todays activities.

I am gaining a very fair grasp on graphing in Excel... I definitely want to incorporate using Excel in my classroom and show our math teacher this information. I'm excited.
