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.
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
A little over 1 year ago, I received a phone call that changed my life. I had been selected to become a PolarTREC Teacher and would be heading to Antarctica in the fall of 2017. Words cannot adequately describe the joy and excitement I had in that moment. I knew I was headed for
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
Teacher Jennifer Bault with researchers Hongjie Xie and Yongli Gao discuss the research looking at Seasonal Ice Production in the Ross Sea from McMurdo Station, Antarctica. A video associated with slide #21 can be seen here:
