Addition to Final Topic

As I stated in my last topic, I'll be using Elodea instead of blue green algae. Elodea use photosynthesis to obtain food just as blue green algae does, and Elodea is better because blue green algae for multiple reasons. Blue green algae does not serve as a food for under-water organisms, because it is lethal to animals, and dangerous to human skin. Elodea is a water-plant eaten by some organisms, and easier to test because it's larger.

But here's an update: I'll be using an oxygen-dissolving sensor to test the amount of oxygen that the Elodea is producing. I predict that the Elodea will produce less oyxgen when exposed to UV radiation.... but then again, I could be wrong. Oh god. Let's hope not.
