Nothing to do with Cumbria, but I put a lot of effort in so might as well share - did it for an interview lesson (high ability Y10), I'll attach videos, other docs etc. (it was for GCSE OCR A - past Q from 2008)
I have lots more stuff by the way, so if you ever need a video / doc / etc. on something specific related to this, let me know and I'll see if I've got something relevant...
