Put the students into groups and show them a selection of clips from a range of different genres. Ask them what age they think they are suitable for. Some interesting choices might be violence in cartoons/family blockbusters, also shocking images in documentary and the news.
Repeat the exercise, giving the students copies of the BBFC Guidelines for each certificate - ask them to use the BBFC guidelines to judge what certificate the film 'should' receive. You can then reveal how close they are to the original certificate.
