These are 2 lessons I use with my students when showing them a documentary. The word docs are set up for "Super Size Me" but will work with any documentary you would use. There are 2 lessons here.
Lesson 1 - Describes the elements of a documentary and has students identify those elements using a graphic organizer.
Lesson 2 - Describes how Documentaries bring up good questions for discussion. Students pay attention to the main themes in the documentary and come up with questions of their own.
