Lesson 3 Teachers My Teacher Graham Lawrence, 29, science author who gives presentations on TV, went to Overton School, 1981-1989. I haven't seen Mr Jenkins since I left school but I often think about him. I wasn't very good at most school subjects. I suppose I was a bit lazy and now I wish I'd done more work, especially in maths. The only thing I can remember from school maths is that the angles of a triangle add up to 180 degrees! But when I was 15 and went into Mr Jenkins' class, I really became interested in a subject for the first time. Before Mr Jenkins, science had simply been a subject full of strange words to me. I had no idea what an atom was and I didn't really want to know either!
