Recently our Year 10B students visited the Sydney Institute of Marine Science as part of their Geography studies of Environmental Changes and Management strategies. They conducted field work on Clifton Gardens Beach, using quadrants along a transect to identify plastics and collect sand samples in order to test for microplastics. They also spent time in the SIMS aquarium and discovery centre, where they gained a deeper understanding of the importance of maintaining biodiversity in Sydney Harbour Estuary.
