Year 12 IB trip to Koh Chang

The IB Diploma Year 12 trip to Koh Chang started off with Mr Thorp and Mr Emery demonstrating how to do river gradient, flow rate, rock roundness and kick tests in the pool ready for the field work tasks during the week. Despite a wet and stormy start to Yr 12s river study they managed to survey 6 stations, where they measured gradients, flow rate, pH, oxygen levels and temperature as well as doing a transect and biodiversity survey at each site. The next day 6 more stations were done and the river was thoroughly surveyed. They also carried out continuous and interrupted transects on the rocky shoreline and swept the beach for plastic. A survey of locals and tourists was also carried out to ascertain their views on plastic usage and pollution. Lastly a trip on a paddleboard along the estuary allowed them to observe the mangroves and the impact of tourism. The day finished up with a sumptious seafood dinner and a late evening session inputting the day’s data and plotting kite diagrams.
