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
I spent a month on a boat in the Arctic as part of the 28 member Science Team that lived and worked alongside the 53 member Crew of the Canadian Coast Guard Ship Louis S. St. Laurent, a 392 foot icebreaker out of St. John's, Newfoundland
View sequential still images of thermokarst (thawed permafrost) at Horn Lake in northern Alaska during the summer of 2010. The video was made by researchers studying the responses of Arctic landscapes to permafrost degradation.
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 The sediment, withdrawn in cores and shipped to labs in Germany, represents a continuous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 Polar Resource Book - Polar Science and Global Climate: An International Resource for Education & Outreach - was written to ensure that the efforts catalyzed by the International Polar Year (IPY) will continue to inspire educators, students, and emerging polar researchers with a shared commitment to outreach and education.
This 250 page book edited by Bettina Kaiser and others
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
Students will observe how soils and rocks of different densities behave in wind and in water. They will make predictions and careful observations as they learn about sediment transport and sediment rates in streams and rivers.
Tunnel Man is a super hero who lives in Ice Tunnels, and teaches children and adults about the unique geomorphology of Alaska. Tunnel Man is played by Kenji Yoshikawa, a Research Associate Professor for the Institute of Northern Engineering at the University of Alaska Fairbanks (UAF). Tunnel Man's fun and educational videos were produced as part of UAF's participation in
