My youngest brother is in year 9. His homework is to write a short speech lasting between one and a half to two minutes covering an issue he feels strongly about and he came to me a minute ago and says he wants to write about sexism and feminism 
Never mind that this is due at 9am tomorrow and he says, "But I need help, I HAVE given you loads of warning!" 
He doesn't have much time (either to do the thing or to actually speak) so I think going for the basics is best. And a lot of his class are little bastards difficult and will give him a hard time so he's being very brave.
So far we've decided to talk about 'girly' being an insult and street harassment.
Any more, fairly basic, suggestions of how you'd try to get 13/14 year old kids to think about sexism? (Boys and girls in the class by the way.)
(Off to eat in a mo but I'll be back later - thanks in advance for any suggestions!)
