Bridges is creating a STEM (Science, Technology, Engineering, Math) based game sponsored by the MacArthur Foundation. We will be working in partnership with the Field Museum of Chicago to create Flash based simulation that explores the goal of preventing Asian Carp from invading the waters of Lake Michigan. With the support of the carp scientists at the museum to ensure accuracy, we also aim for our experience to be fun and engaging. Through the game, it is our goal to introduce players to the complex global dilemma of managing invasive species. The game will include the sociological, scientific, and economic roadblocks that tend to slow down effective prevention. This game, "Invasion!" will be playable in Field Museum workshops and classes as well as on the internet.
