I've just started to do a mock Edexcel GCSE Unit 1 for my year 10s to get them used to evaluating their work and also to ensure that they are comfortable and confident in using the skills and techniques that they've been taught this year. I totally recommend http://www.rhinegold.co.uk/magazines/magazines_catalogue.asp?m=1&id=144 for SOW! You have to sign up, but it's free and you can download brilliant schemes for free as well. I'm using the unit 'Fame' which uses Lily Allen's 'The Fear' as an audio stimulus and includes others as well. My year 10s can be quite difficult and lack focus sometimes and they are already so engaged, I can't shut them up in discussions about it. As you are only required to do a 6 hour workshop on the chosen theme, I am going to lead the workshops and then let my group devise a piece around the theme and perform it at the end of term, just because it will be a nice easy end to the year for all of us and they love to devise. Hope this helps, trust me, that website has been a godsend! Just scroll down to the bottom of the page for the SOW.
