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
Students will observe how soils and rocks of different densities behave in wind and in water. They will make predictions and careful observations as they learn about sediment transport and sediment rates in streams and rivers.
Students experiment with a “blubber glove” to experience how insulation affects heat transfer, and how the adaptation of blubber helps penguins as well as seals, whales and walruses survive in bitterly cold waters.
Students will sort organisms found in the Bering Sea into food chains and gain an awareness of the flow of energy and nutrients in the Bering Sea Ecosystem.
Objective
Students learn about the different organisms that live in Alaskan waters by playing the Fabulous Food Chain Game. In playing the game, they become aware of the flow of energy
Maggie Prevanas joined scientists in the Bering Sea where sampling to measure the productivity of the Bering Sea Ecosystem was conducted. Maggie learned about the role microscopic organisms, diatoms, play in algae blooms, carbon cycling, and global warming. Maggie developed a lesson using scientific illustration to introduce diatoms to her students.
