Feature story on David Walker's Carbon in the Arctic expedition and permafrost science in the Spring 2020 issue of The Classroom Teacher, the quarterly magazine of the Texas Classroom Teachers Association. Article begins on page 12.
Scientists are studying the effect of climate change on vegetation in the Alaskan tundra. In this activity, students will analyze data collected from control plots and plots with Open Top Chambers (OTC's) over them. An open-top chamber is like a tiny greenhouse that increases the temperature in a vegetation plot an average of 2-3 degrees, simulating the effects of
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 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
After spending 5 weeks in the Arctic learning about tundra vegetation and phenology, Alejandra Martinez wanted to have her students observe the growth of plants in their school. In this lesson, students will grow plants in multiple locations and track their growth to compare their phenology.
Objectives
Students will learn what phenology is and make observations about plant growth
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).
KUT (Austin's NPR Station) news report (video, article, and radio) on PolarTREC teacher David Walker's Carbon in the Arctic expedition. The story aired on Morning Edition and Texas Standard in late-September, 2019.
PolarTREC (Teachers and Researchers Exploring and Collaborating) is a program that pairs US educators with field research experiences in polar regions. The program is managed by the Arctic Research Consortium of the United States (ARCUS) and receives funding from the National Science Foundation (NSF) Office of Polar Programs. The long-term vision of PolarTREC is "to create
South Texas is pretty far removed from the Arctic. When I mention climate change in my classroom, my students think of emaciated polar bears roaming the Arctic Ocean for a few minutes and then carry on with their day. I needed to find a way to connect what was happening in the Arctic to
