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
The work of professor Bryon Crump, graduate student Natasha Christman, and PolarTREC teacher David Walker is highlighted in the weekly newsletter of the Oregon State University College of Earth, Ocean, and Atmospheric Sciences (On the Horizon).
The Aleutian Islands, between Alaska and Siberia, have earned the name "Cradle of the Storms" due to their wild weather. Students will view a two-part series about the Aleutian islands and answer questions related to the film.
Objective
Students will learn about the Aleutian Island chain in Alaska and answer questions to reinforce learning.
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
Diatoms are one of the main kinds of phytoplankton we found blooming in the Bering Sea. They are so beautiful, little glass houses with green gems inside. They occur in huge numbers in the Bering Sea in the initial spring ice melting algae bloom. Having one to touch and look at puts a face on what it is
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.
