The objectives of this lesson are:
* Students will know that climate change is happening most quickly in Arctic regions.
* Students will know that a warming climate is causing permafrost to thaw.
* Students will know that thawing permafrost is impacting infrastructure in Alaska, including roads and buildings.
* Students will design an engineering solution to create stable
Students will use a model to explore the relationships between sunlight and release of carbon dioxide (CO2) from thawing Arctic watersheds.
After studying the carbon cycle, students are asked to reflect on how natural phenomena – thawing of permafrost, interactions of soil microbes on dissolved carbon, and amount of sunlight – interconnect and influence the release of CO2
The report is written by teacher participants upon return from their field expedition portion of the PolarTREC program. It summarizes the benefit of the expedition to the teacher, a description of activities, and a summary of how teachers plan to link this experience in classrooms and communities. This is a public document that will be posted in teacher portfolios and

The long-term objective of PolarTREC teacher Lesley Urasky's expedition research in Antarctica (Glacial History in Antarctica) is to determine the rate at which glaciers have receded since the Last Glacial Maximum. This lesson is designed to give students an understanding of the Last Glacial Maximum, the climatic conditions that lead to glacial periods, and how the rate of glacial
During Lesley Urasky’s expedition, “Glacial History in Antarctica”, the team collected rock samples which were taken back to the University of Washington to be dated using cosmogenic (exposure) dating. This method of radiometric dating measures the ratio of isotopes of Beryllium (9Be:10Be) produced by the interaction of cosmic rays with minerals in rocks. This lesson will introduce the student to
