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

Scientists in Siberia are seeing trends of more severe and widespread wildfires. By observing and measuring larch forests, they are trying to understand how the forests are changing. What do these trees need to survive? Are they getting what they need? Students will plant lodgepole pine seeds providing some with all the necessary components for survival and others missing
Scientists in Siberia are seeing trends of more severe and widespread wildfires. Larch seeds are dispersed by wind. Experimentation is currently underway to determine distances larch seeds can disperse from viable, mature larch trees. Students will explore how various types of seeds are dispersed to get what they need to survive.
Timeframe: 90 minutes
Grade: K-2
Students will learn to:
* Observe and record weather patterns
* Process data by creating graphs/charts
* Compare actual weather data from the Siberian Arctic to local weather patterns, draw conclusions and make future predictions concerning weather patterns.
Big Idea
Why do people need to track weather over time?
Lesson Preparation
You will need a thermometer, tracking calendar, and
This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted at Toolik Field Station in Alaska. The purpose is to introduce students to Van Krevelen diagrams, which are used to interpret results of high resolution mass spectrometry and characterize the compound classes present in complex organic mixtures. Students will
This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted during summer 2019 at Toolik Field Station in Alaska. The purpose is to expose students to photooxidation, one of the main pathways by which organic molecules in Arctic streams are oxidized into carbon dioxide. Different teas will be used
The work of professor Bryon Crump, graduate student Natasha Christman, and PolarTREC teacher David Walker is highlighted in the weekly newsletter of the Oregon State University College of Earth, Ocean, and Atmospheric Sciences (On the Horizon).
