I have an interview on thursday and I am completely at a loss what to teach. I have to teach a 20 minute lesson, on absolutely anything I want, to a group of able year 8's. The problem is they don't teach music at the school at the moment, so the pupils won't have any experience of music at a secondary level. There aren't any resources for me to use either. Its an all boys school too. I am tempted to do something with rhythm, and explore body percussion. I don't know if this is a good idea or not though. I am a PGCE student atm so am going to ask my tutors advice too, but thought I would get some ideas from here. Thanks!
