Great insights into waste, litter, recycling. Some engaging videos. Lots of good links on coolmath website.
Feel confident enough to spend some time creating a unit.

I found the video by Jo Boaler particularly challenging to update my knowledge of research into how students (especially the strugglers) become confident in their Maths. The waste audit idea has the potential to be a great initiative on (at least) two fronts; namely student engagement and making a positive environmental impact (more by changing student and staff behaviour than just the reduction in waste at the school).
