We had an exciting and productive day investigating the Afon Caerfanell in which most students, and one teacher, managed to take a dip in the river at some point.
The day started with a refresher lesson about the water cycle, river features and processes. After this we headed up into the Brecon Beacons to begin our river investigation. The students had to find out about the characteristics of the river in its upper, middle and lower courses. In between falling in the river we measured the river's width, depth, the gradient, water velocity and type of sediment.
By the end of the day most students had managed to take an unplanned dip, with Mrs Margrave taking the plunge at the first site.
In between taking measurements with rulers, tape measures and clinometers, Dylan and Laurie found some fantastic fossils of ancient corals and we also witnessed a mountain rescue training exercise. Some brilliant field sketches were drawn by Daniel and Haruna, with everyone else doing their best to do the beautiful scenery justice.
Emptying wellies, hot showers and dinner followed a hard day's work, with spreadsheets and data analysis after our fish supper.
Looking forward to Blaenavon and Big Pit tomorrow!
