As part of their physical Geography fieldwork KS4 students have spent time out of school to investigate whether ‘the benefits of Penzance’s coastal defences outweigh the costs?’. Students completed wave counts, environmental quality surveys and field sketches; collecting evidence on whether the sea defences are needed. They also used anemometers to measure wind speed and staff demonstrated how to measure longshore drift to see if sediment was moving down the coastline. All of the data collected will be analysed and presented in class where students will then conclude whether the sea defences were worth the hefty price tag.
