Room 15 have been learning about the indicators of a healthy stream and today with the help of Mel McCoglan went
walked above Easby Park to do some tests.
We checked the water clarity, by filling up a metre tube and moving a black spot until we couldn't see it any more.
Then we were finally able to get our shoes wet and try find different micro invertebrates in the stream.
If we found highly sensitive ones, like the Mayfly, then we would know that the health of the stream was good. We had two rare finds a water spider and a young elver Eel.
