well, as a chemist perhaps you'll forgive me for dwelling largely on what we as chemists do, but of course it's not only the chemists in the school of chemistry and molecular sciences who do things for schools — it's right across the area — but each year, for example, we have a week set aside for sixth form visits, in which parties of sixth formers come to the school and we're about to talk to them about university entrance, about what goes on in universities, but, most importantly, to show them some of the apparatus which they don't have at school but which they've probably heard about.
