So today we went to go see a some sort of Pitt lab. Apparently, they were testing pesticides on not only one thing, like a tadpole in a petri dish, but a whole ecosystem with not only tadpoles, but also snails and plankton and crustaceans oh my! There were more than forty of the tub like test groups so i guess it must be one heck of a job to get the readings from all those. After seeing the test tubs we went to a small stream where there were nets full of different kinds of leaves like maple and oak and we soon discovered that different aquatic invertebrates eat different "stuff."
