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
A short newspaper article featuring PolarTREC teacher Dave Jones in the 8/8/2017 issue of the Missoulian! He will set sail on 9/6/2017 aboard the Canadian Ice Breaker CCGS Louis S. St-Laurent with researcher Mike DeGrandpre heading for the Beaufort Sea.
PolarTREC teacher Emily Dodson participated in a scientific expedition in the summer of 2014 at Kangerlussuaq, Greenland. Emily’s book is a telling of the science story behind the teams work and Emily’s participation as an educator and field assistant on the PolarTREC expedition.
Emily Dodson-Snowden, a sixth-grade science teacher at Morton Middle School, didn’t have a typical summer break. She spent three weeks in Greenland studying how climate change influences plant/pollinator interactions and plant reproduction as part of PolarTREC (Teachers and Researchers Exploring and Collaborating).
Exploration of the Antarctic continent did not occur until the late 1800’s, and the South Pole was first reached on December 14, 1911. Courage, planning, and technology have been the main components of Antarctic exploration from the earliest days. This classroom activity is designed to highlight the historical elements of the past 100 years of exploration in Antarctica and
Antarctica is the coldest, driest place on Earth with a fairly limited number of native species which have adapted to these extreme conditions over millions of years. As a result, it's not very likely that a non-native species would survive there . . . right? Actually ever since exploration and exploitation of the Antarctic region began in the 1800's
This story in Discover magazine profiles the work of the WISSARD (Whillans Ice Stream Subglacial Access Research Drilling) project team and the challenges faced by drilling thousands of feet into the West Antarctic Ice Sheet to reach a lake buried for millennia.
