This week our Water Explorers went on a field trip to the Cor Burn as part of their MiniSASS to assess the health of a local water supply. Simone from the Tyne Rivers Trust demonstrated how to take a kick sample of the sediment and living organisms on the stream bed. We then collected their own samples and placed them carefully in their collecting trays. It was really exciting to identify eels, bull-headed fish, mayfly larvae, caddis fly larvae and many more mini-beasts using our classification sheets. We decided that the stream was in a healthy condition as there was so much biodiversity - we live in a reasonably rural area but sometimes even farmland can cause pollution. We had an incredible morning and linked the importance of the stream to Sustainable Development Goal 15 (SDG15) as fresh water streams are part of Life on Land.
Simone also came to visit our Water Explorers in school to discuss the amazing life cycle of the mayfly in more detail. Mayfly are very important as they are a food source for other organisms in the stream. They have a really interesting life as they live in the water for up to 2 years and then, when they hatch, they only last around 24 hours before they die.
