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
The Importance of Teacher/Researcher Collaboration
Collaboration such as this offers a window into the science rarely seen by teachers and their students. It allows the public/students to experience, in real-time, relevant data collection of the 21st century. Furthermore, experiences such as these demonstrate the universal factors of the scientific process. It does not matter if we are practicing science in
PolarTREC Educator Amanda Ruland and researcher Jennie DeMarco describe the research taking place on post-fire tree regrowth within larch forests of eastern Siberia and consequences for climate feedbacks through changes in Carbon storage. This event was broadcast live from the Northeast Science Station in Cherskii, Russia on 8 July 2019.
PolarTREC alumna Susy Ellison talks about her two expeditions and how they affected her personally and professionally. Researcher Jeff Rasic joins in to talk about what it was like to have a teacher in the field for the Early Human Settlement in Arctic Alaska 2011 expedition.
Teacher Betsy Wilkening and researchers publish an article in the Journal of Geophysical Research stemming from their work on the PolarTREC OASIS project.
Students will use marshmallows to simulate toxins in the environment. Concentrations of these toxins will be modeled and calculated as they bioaccumulate up the food chain. Methylmercury and POPs are substances that bioaccumulate in the Arctic food chain. OASIS scientists studied these in Barrow, Alaska. (See Ocean Atmosphere Sea Ice and Snow (OASIS) Project at www.polartrec.com)
Students will discover how a simple action such as turning on a television will lead to toxins in our food supply. Many of these toxins concentrate in the Arctic because of long-range transport of pollutants in the atmosphere. Scientists in the OASIS project (http://www.polartrec.com/ocean-atmosphere-sea-ice-and-snowpack-interactions) study these pollutants in the Arctic. Students will learn about actions that they can take to
