Students will be able to:
* Analyze graphical data to draw conclusions
* Compare and contrast the chemical structures of nitrous oxide and carbon dioxide
* Explain how differences in the structure of nitrous oxide and carbon dioxide lead to differences in their reactivity and functions as a greenhouse gas
* Argue how changing shrubbery impacts climate change
Students will be able to:
* Graph, analyze, and predict data
* Develop claim, evidence, and reasoning
* Explain how permafrost is made, current conditions, and its impacts on climate and humans
Preparation
* This lesson plan can be taught either in the classroom or virtually online. Instructions on how to teach both ways are given in the Procedure
It’s sometimes a common and depressing comment to hear from your students, “I’ll never use this in my life! Teach me something practical like how to pay my taxes!” As teachers, we strive to make learning relevant to student’s lives, but for a multitude of reasons sometimes your lessons just don’t have that
PolarTREC educator Kate Steeper and researcher Dr. Syndonia Bret-Harte discuss the 2019 fieldwork and research that is occurring on a project looking at shrubs, snow, and nitrogen in arctic Alaska. This event was broadcast live from Toolik Field Station, Alaska on 15 August 2019.
An article describing Kevin Anchukaitis' work at the Lamont Doherty Earth Observatory. Tree rings embody a record of climate change going back thousands of years, and they grow on every continent except Antarctica. “They let us reconstruct climate around the world, in both space and time."
Article describing PolarTREC teacher Susy Ellison's recent expeditions to Alaska to take part in a tree ring study in the Arctic National Wildlife Refuge and an archaeological expedition in Kivalina.

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
This lesson was modeled after some of the routine activities undertaken by the geologists on the Kuril Island Expedition.
Complete the following activities:
* Day 1 To measure a simple topographic profile with a level instrument or hand level and stadium rod.
* Day 2 To use the measurements from Day 1 (and/or actual measurements from the Kuril
