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
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
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.
