How can the ocean be colder than 0 degrees C, the temperature at which water freezes? As it turns out, the concentration of the particles (in this case, the ions from the salt) in ocean water lowers the temperature at which the saltwater will freeze. Students will learn how ocean water freezes at a lower temperature than freshwater by
Mount St. Mary's College in Los Angeles profiles one of its alumni, teacher Cristina Solis who also happens to be a PolarTREC alumnus. Read about her journey to become an educator and her participation in a PolarTREC study of microbial activity in thawing arctic permafrost near Barrow, Alaska.
Newsday reporter Jennifer Smith blogs dispatches from Toolik Lake, Alaska about science underway at the research station, including the work of researcher Amanda Koltz on predatory spiders.
A poster by PolarTREC alum Dan Frost describing the integration of Arctic research into secondary education through a field season in Svalbard. It details possibilities for curriculum building and outreach through Arctic field work experience.
Students will conduct a soil study by investigating pH and water absorption.
Objectives
Students will learn:
* How to describe the composition of soil and explain how it forms.
* That soil is made up of tiny particles of rock, plant, and animal matter.
* How to determine whether a solution is acidic, basic, or neutral.
*
Students will investigate what a carbon footprint is and calculate their own personal carbon footprint. Finally, students will develop ways to reduce their carbon footprint.
Objectives
Students will know that the principles of chemistry underlie the functioning of biological systems.
Students will know that carbon, because of its ability to combine in many ways with
In this one hour webinar, PolarTREC teacher Nick LaFave conducts live event for students and the public on his work at Toolik Field Station studying Predatory Spiders with researcher Amanda Koltz.
In the field with Michael Sheriff of the Institute of Arctic Biology, University of Alaska Fairbanks. Tagging squirrels near the Atigun River, North Slope, Alaska. Video by Nick LaFave.
This one hour presentation by Dr. Al Werner is a professional development opportunity for educators to learn more about earth and geoscience research in Svalbard, Norway. Some noticeable technical issues are resolved a few minutes into the presentation.
