At morning assembly we were introduced to the students, and the headmistress sternly ordered them to obey our instructions. Initially reserved, they soon realised our sessions did not in fact require the rigid discipline that was typical of their regular classes. In no time at all, a stream of excited students were dashing out of the classroom and onto the football pitch, where they proceeded to run and jump around, all in the name of sports science. Back in the classroom they measured their pulses, concluding that their heart rates had gone up during the exercise, and engaging in a discussion about the various associated processes that had taken place in their bodies -- which they had just experienced first-hand. Since classroom time was limited as always, we decided to take science outdoors and into the schoolyard.
