May 2015
We have been doing some awesome work in Inquiry.  We have been investigating water and pollution.  I asked the kids "Can polluted water be cleaned?".  We put some of our lunch into a trough of water and left it there for several days.  The kids thought you just needed to clean the rubbish out but soon realised that the water is now polluted.  We went to the local treatment station to see how they treat the Carterton water supply and decided to make our own water filters to clean our polluted water.  The water was certainly better after we filtered it but it was still undrinkable.  We redid the experiment by thinking of what went well and what we could do to make our water cleaner.  When we redid our water filter systems we used some of the same material but added different products such as sand and grass.  The polluted water was cleaner but not for human consumption!!!  We think we may have left it too long before filtering it.  Now we are going to look at the effects of pollution on our animals and marine life.  We are also going to do some more experiments.  Thank you to those parents who are helping their kids at home with their homework.  We have had some fantastic presentations.  Kirsty Hull
