Students learn about the connections between organisms in the ocean in this kinesthetic activity. Each student is given a card, identifying an organism, its food source, and its predators. Holding the end of a ball of yarn firmly, the ball is passed from organism to organism as they are linked in the predator-prey food web. Once all students are connected in the food web, an extinction event is simulated by removing an organism. Those students remaining pull lightly on the web, to demonstrate how other organisms are affected by the loss. Students identify the impact of biodiversity loss throughout the food web. This activity is supported by a textbook chapter, One Global Ocean, part of the unit, Losing Biodiversity, in Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.
