Today 1st and 3rd periods went to the Johnston Mill site on New Hope Creek. We tested the water for temperature, pH, Nitrates, Nitrites, and Phosphates. We flipped over rocks and collected stream invertebrates to identify and to help us determine the quality of the water. We also collected minnows, crayfish, and frogs. The weather was a little cool and the water levels were low, but we were able to find quite a few creatures. Tomorrow 2nd period will be going and doing the same thing.
