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
There is a plausible explanation for how carbon dioxide molecules could interact with water molecules thereby forming a solution where the carbon dioxide is the solute and water is the solvent (as it usually is). The weak inter-molecular attractive forces rely on the polarity of the water molecule and the high density of electrons at either end of the
When a bottle or can of carbonated beverage is opened the carbon dioxide is allowed gas to come out of solution. This is because there is a pressure differential between the carbon dioxide in the liquid and carbon dioxide in the air. The pressure in the liquid is higher than the pressure in the air so the carbon dioxide moves
This article describes PolarTREC teacher Nick LaFave's upcoming expedition to Toolik Lake, Alaska where he will be studying wolf spider populations with Duke University researcher, Amanda Koltz.
This article describes the remarkable efforts of a team of scientists to extract cores from deep under a frozen lake in Siberia, Russia. PolarTREC teacher Tim Martin joined the project which will provide an astounding record of past climates preserved in layers of lake bed sediment. The sediment, withdrawn in cores and shipped to labs in Germany, represents a continuous
The attached Lands and Life flyer, produced by the International Polar Year (IPY) Programme Office, includes a summary of terrestrial polar ecosystems, from southern cold maritime islands to dry continental deserts in Antarctica and from tree line across the continental tundra to remote northern islands in the Arctic. An attached activity allows students to build a small scale model of
Icy IPY activities can be downloaded in word documents and tried in your classroom. From 'Blubber Gloves' to 'Experiments with Ice and Snow', there are a wealth of different activities to introduce students to the Polar Regions or complement their existing knowledge of the Poles.
The International Polar Year is a large international effort that has involved over 200 projects
Share in the excitement of unearthing a biface and other archaeological treasures, as Alaskan researchers explain how they discover and document early human settlement sites across arctic Alaska. This video is part of a larger story on the Frontier Scientists website (http://frontierscientists.com/), the University of Alaska Fairbanks' portal for sharing the Arctic's newest discoveries.
Travel back in time as scientists and PolarTREC teacher Karl Horeis take you out to their dig sites to uncover hidden clues about early human settlement in arctic Alaska. This video is part of a larger story on the Frontier Scientists website (http://frontierscientists.com/), the University of Alaska Fairbanks' portal for sharing the Arctic's newest discoveries.
Results from PolarTREC teacher Chantelle Rose's research cruise to the Bering, Chukchi and Beaufort seas surprise scientists and may have implications for climate modeling. Read more about the tenacity of life forms living off the coast of Alaska from this National Science Foundation press release.
