The Dry Valleys Ecosystem project (a Long Term Ecological Research program - LTER) has been a continuous line of research since the inception of the McMurdo Dry Valley LTER since 1992. This project seeks to test hypotheses regarding the response of Antarctic biotic communities to changes in climatic conditions over time. I participated in the 30th
Teacher Bill Henske describes the science and fieldwork behind the Dry Valleys Ecosystem Study from McMurdo Field Station in Antarctica. This presentation took place on 24 January 2023.
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
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
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.
Ice is a medium that nearly everyone is familiar with. We put it in drinks, skate on it for hockey and scrape it off our windshields in winter. Ice can be turned into sculptures and can even make for some fantastic winter scenery. Ice can also turn into a kaleidoscope of color and patterns under the right circumstances. Science
This lesson is intended to help students make connections to polar science while discovering how and why sea ice drives deep ocean currents. Students will also learn key terminology related to sea ice and using actual salinity content charts, will graph a typical sea ice core’s salinity as it relates to depth.
