Today, we were fortunate enough to have Kathryn from Watercare come work with our Year 6's to test the water quality of our estuary. We learnt about the factors that can harm our estuary such as litter, car oil, detergent, concrete making and fertiliser run off.
Next we tested water samples and observed macro water invertebrates. The other half of the class picked up litter and hunted land invertebrates. Sadly so much plastic litter had blown into our native bush walk. A big thank you to all the Whanau who make the extra effort to pack a litterfree lunch.
Next lesson we will analyse our results and compare them with last year.
