Water testing


The student leaders went down to Johnson reserve to test our local waterway we had to see if it was healthy or unhealthy.  It was a long process of testing if it was clean or dirty but we got a positive 8 on our ph test. This means that it is healthy and flowing. The sign that it isn't healthy is when it's stagnant this means that it isn't flowing. My favourite was when we did the  Ph test because we got to match the colours to the results.
