Have just dragged myself and pupils through the Year 8 heat transfer section. Watching paint dry would seem like such an improvement on watching water cool down. I pride myself on my enthusiasm for all aspects of Physics and usually manage to, in turn, enthuse at least some of the pupils. However, I just don't seem to be able to summon any interest in this bit at all. Am I alone? Does everyone else find this topic fascinating? Anything more interesting than cooling curves, potasium permanganate and bubble wrap?
