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
Note: This event was not for our typical classroom-based education audience.
WAIS Divide (West Antarctic Ice Sheet), where the Velvet Ice team conducted its research, has recently be found to be one of the most vulnerable areas of Antarctica to global climate change. If recent predictions hold true, major glaciers in WAIS could collapse within 100 years, triggering massive shifts
This one hour event is an introduction to the expedition with Yamini Bala and her team. They address life at McMurdo and what it will be like at their remote field site at WAIS Divide (West Antarctic Ice Sheet).
This PowerPoint presentation could be used as part of an introductory or supplementary unit on Antarctica. The presentation includes stunning visuals and general facts about Antarctica.
