Pollution

David McGrath and his PHD student Ciara came to visit our rang a 1 & rang a 2 classes to talk about the pollution of our waterways. They brought some insects that they collected from our local river and were able to tell us that our local river is quite clean as those insects would not survive if the river was polluted. We had great fun figuring out which insects were in our sample and using the chart to determine which insects they were.
