The students are participating in a reality TV show called "Castaway" where they will be marooned on an uninhabited island for an extended period of time with no means of communication or transportation. They must work together in groups to create a long-term plan to ensure their survival by addressing what resources they need, the tasks required to survive, and whether their decisions will be sustainable over many generations. The groups will present their plans to the class and receive feedback before their classmates vote on the best survival plan.
