Our river study culminated in a visit down to the Mangapuhoe stream that runs alongside the road that disects our school. We were trying to catch critters to assess the water quality in the stream. We learnt how to do this when we went to the National Trout Centre on our class trip. While we were there we searched for critters in the Tongariro River. This video also shows how we were able to use green screen techniques for a bit of fun.
