Students will conduct a demonstration that will help them gain a better understanding of the water cycle and runoff in a watershed. They will be able to replicate arctic and non-arctic watersheds by varying the size of the watershed. They will be able to visualize the difference in runoff by creating hydrographs of these different locations.
Students will investigate the breadth and depth of science taking place in the Polar Regions by reading and learning about one PolarTREC expedition and sharing it with the class.
Objectives
* To expose students to the wide variety of science happening in the Polar Regions
* To help students understand the process of science by examining one
This one hour event by Melissa Barker explains the research being done at Toolik Field Station, Alaska on nutrient transport in arctic watersheds. She is joined by team member Dr. Sarah Godsey.
View sequential still images of thermokarst (thawed permafrost) at Horn Lake in northern Alaska during the summer of 2010. The video was made by researchers studying the responses of Arctic landscapes to permafrost degradation.
PolarTREC teacher Melissa Barker, a high school biology and environmental science teacher, shares her thoughts about her upcoming expedition to Toolik Lake, Alaska where she will learn about changes in water and nutrient cycles in the arctic tundra. The external link provided includes a video interview with Melissa at her school.
PolarTREC Teacher Melissa Barker is a feature story for her school in Colorado. She is heading into the field with Dr. Tamara Harms to study Arctic watershed systems.
This PolarConnect event was conducted with PolarTREC teacher Claude Larson, and members of the research team that she worked with on the Prehistoric Human Response to Climate Change 2010 project in Kamchatka, Russia.

Students will independently explore the PolarTREC expeditions, and reflect on the scientific questions, discoveries, and outcomes of the work that is or has been done.
Description
Students will visit the PolarTREC website at www.polartrec.com, where they will find a teacher who is in the field presently, or was already in the field. You may select one expedition
Students are presented with an actual series of tundra photos, which they use to develop a hypothesis for which sort of ground cover will have the most/least permafrost depth. Then they are given a set of actual data and use this to test their hypothesis
Objective
Students will:
* understand what permafrost is and how it develops
