This project is similar to the drama workshops which include you as a character but made to be a class interaction. Emulating shows like Jerry Springer where people come on to discuss their problems or why they are such freaks. The purpose is to involve all students by having them as the audience who can ask questions to the guests on the show.
Give each group the information and the group topic prior to the class and if you know such shows like Jerry Springer, explain to them what type of things happen on these shows.
In this project, you are part of the audience and not a guest nor host as the students are in control. There are only five groups and the aim is that the audience ask a lot of questions. You can ask questions to get the discussion moving.
The home shopping channel in the classroom; students have to invent a new product and then sell it. There is no limit to what they can invent as they have to convince the class that it's worth buying.
