Teaching group of Yr7 boys.
One has been self-taught and needs watching carefully as hasn't always adopted the safest practices. This was a novel experience, as usually I get pupils who come with either no knowledge or well-developed skills. In particular, I felt a duty of care to try to educate him into ways to do things better at home (eg. he uses a self-stitched harness for abseiling out of trees), without killing off his enthusiasm for exploring.
