Hi there, I'm a trainee and have just got my first interview on Monday. I have to do a lesson for a year 9 group of mixed ability on an introduction to atomic structure and I'm stuck for ideas on how to make the theory interesting. The lesson is only 30 minutes long and must include a good aspect of afl. I thought I could have a people model as a starter and finish with something like a pyramid plenary but can't think how to make this not just me talking... Any help or ideas would be greatly appreciated. Thanks!
