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 data plotting lesson compares different stratospheric ozone data collected at the South Pole in September 1969, September 1998, September 2008, January 1999, and January 2008. This ozone comparison activity allows students to make conclusions about the annual and seasonal ozone hole as well as overall ozone concentration changes over Antarctica. Students use authentic data collected at the
This data plotting lesson is about temperature changes throughout the atmosphere. The data was collected together with the ozone data in January 2008.
The temperature vs. altitude profile allows students to make conclusions about annual and seasonal temperature changes in the atmosphere up to about 35 kilometers in the stratosphere. The best part of this lesson is using
Craig Kasemodel is joining researcher Lee Cooper aboard the USCGC Healy in the Bering Sea. This live event highlights some of the research and activities taking place on board the ship. There were about 11 parties who joined the event, and there were about 60 students.
