This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted during summer 2019 at Toolik Field Station in Alaska. The purpose is to expose students to photooxidation, one of the main pathways by which organic molecules in Arctic streams are oxidized into carbon dioxide. Different teas will be used
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).
As the homepage of the website describes, "The beauty of the Arctic, its precious and fragile nature, its critical role in maintaining a stable climate for the planet, and the rapid rate of change that is occurring there must all be conveyed to the general public. Here, through digital story telling, we put a human face on science, life, societies
Students will discover how a simple action such as turning on a television will lead to toxins in our food supply. Many of these toxins concentrate in the Arctic because of long-range transport of pollutants in the atmosphere. Scientists in the OASIS project (http://www.polartrec.com/ocean-atmosphere-sea-ice-and-snowpack-interactions) study these pollutants in the Arctic. Students will learn about actions that they can take to
Using photos from a variety of websites, including the PolarTREC and SCINI websites, students will identify organisms to phylum and/or class level (e.g. polychaetes, starfish, brittle stars, sponges) and then research the primary foods that these organisms eat. They will then develop a simple food web for these organisms.
In the Polar Discoveries Section of the Online NewsHour, professional photographer, Spencer Brown, uploaded a photjournal of scientists working as part of the OASIS campaign in Barrow, Alaska in the Spring of 2009.
Learners from 6th – 12th grade will investigate different science projects in Antarctica through the PolarTREC and the USAP websites. They will then make a short PowerPoint (or similar) presentation to the rest of the class. Learners can work independently or in small groups.
Objective
Students will become familiar with the wide variety of science that occurs
