This content has been created with the intent for the teacher to develop it to best suit their classroom setting. In its most basic form, students are asked to analyze wet and dry berry data to determine how water content changes (or doesn’t) for several berry species over the course of one season.
This lesson has multiple stages or
The night before I left Alaska I stayed up chatting with some of the scientists in the Toolik dining hall talking about my return to “normal civilization”. We spoke about the little habits that you pick up while at the field station and aren’t sure you’re going to let go (wearing sunglasses 24/7) as well as
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.
