Students meet to plan how to edit their documentaries. They may decide to 
intercut some sections from the news broadcasts they made in part1, and they 
may also decide to write and record some more scenes for their documentaries. 
Encourage them to use a wide range of the editing techniques mentioned in this 
section. When the documentaries are ready, they should ‘broadcast’ them to the 
rest of the class, or post them on a class website.
