From the National Academy of Sciences comes Extreme Event, an in-person role-playing game that simulates "build[ing] community resilience in the face of disaster." In this hour-long exercise, participants are assigned roles and choose between three different disaster scenarios (earthquake, hurricane, or flood), then work together to help their community survive. Extreme Event is designed to be played by teens and adults in groups of 12-48 participants, making it well-suited for classrooms or adult team-building exercises. All necessary materials, including instructions, handouts, and sound effects, are freely available to download, and the game can be facilitated using either the downloadable script or their web-based "digital game portal" (this option requires the use of seven laptops/tablets). Video tutorials on facilitating the game and creating your own game materials are also available. Extreme Event was developed collaboratively between the Marian Koshland Science Museum (now LabX) and the Resilient America Roundtable (both projects of the National Academy of Sciences), and it "draws on recommendations from the seminal National Research Council report Disaster Resilience: A National Imperative."
