Tragedy of the Commons

Time:  5-day unit with standalone 10-minute activity

Lesson description: Students will learn about the status of global fisheries, play an educational game, plot data on a graph, and finally, strategize for the collaborative management of a common pool resource (the ocean). This unit focuses on a present day tragedy of the commons: the tenuous state of many fisheries around the globe. The unit centers around an educational game that helps students recognize the problem by catching fish (crackers) from oceans (reusable bowl). At the end of the game, some oceans will likely have over-harvested their stock until there are no fish left. Others will have developed a strategy in order to maintain a sustainable fishing industry. The stage is then set for solid discussions of resource management strategies for other shared environmental resources.
