This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted at Toolik Field Station in Alaska. The purpose is to introduce students to Van Krevelen diagrams, which are used to interpret results of high resolution mass spectrometry and characterize the compound classes present in complex organic mixtures. Students will
This lesson allows students to learn about the Arctic through a challenging question and answer game format. Inspired by experiences in the Hidden Ocean 2016: Chukchi Borderlands expedition, the game includes “careers”, “animals”, “equipment”, “climate change”, and “geography” components. The game may be used as a learning tool, a review tool, or an assessment tool.
Students will use marshmallows to simulate toxins in the environment. Concentrations of these toxins will be modeled and calculated as they bioaccumulate up the food chain. Methylmercury and POPs are substances that bioaccumulate in the Arctic food chain. OASIS scientists studied these in Barrow, Alaska.
