I have an interview for a full time job at the school I currently work in. For interview, I have to teach a P4C lesson on any aspect of the science curriculum relevant to year 2. As I just returned from maternity leave four weeks ago, and now mostly teach year one, I'm feeling horribly out of the loop, and really need some topic suggestions. So far, I've been thinking perhaps something to do with life processes and living things, but that's as far as I've got!
