This is the kind of thing I would prepare if asked to present project management to school students. And I would probably adopt a flipchart style. (This would save having to present a monotonous deck of slides.) I would do something really simple. First the students would want to hear something about the kind of projects that are done and why they are important all over the world. Students like to hear about the exciting real world and there's nothing more 'real' than a good project!
