A full lesson (most likely two) based on 'Bowling for Columbine'. Students will need to have seen the documentary before the activity. I use Netflix. Students are given differentiated roles and are encouraged to discuss the issue of gun crime in the US through the eyes of various different demographics. Success criteria and challenges provided for more able students. It's a really engaging topic for reluctant groups and encourages wider thinking. Have used this on higher and lower ability groups and has produced great reasoned and well-thought out debates.
