We went out for two cruises with the kids from the Science Center Camp today. Since it was a bit of a rainy day, we talked a lot about acid rain and how it affects our lake-- and how we are protected by the limestone rocks around our lake. (The picture to the left is of Caroline putting strong acid on several different kinds of rocks to see what would happen). We found out that the pH of the rain was between 6 and 6.5, and that the pH of the lake was between 8 and 8.5. We also got several plankton samples which had many different kinds of zooplankton (tiny animals) in them, although not so many phytoplankton (tiny plants). When we took samples of plants, we found five different kinds in just a small area, including Milfoil and Elodea.
