SCIENCE

We were looking again at water quality for science and the different ways a good scientist could test any waterway for the quality of its water and signs of pollution. We are looking at the local Utuhina Stream.The first test was a clarity test using a clarity tube. We then sifted through net samples taken by Mr Bach from the stream to look for macro invertebrates (water bugs). We found some crayfish (koura) which is a good sign.
