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.
How glaciers in the polar regions respond to continued climate warming is of great concern. Changes in overall glacier velocities and calving dynamics have immediate impacts on sea level. Accurate predictions of how and when ice loss will occur are crucial to forecasting future environmental change.
This lesson results from experiences working in and around Kronebreen glacier in
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.
This lesson was designed to teach pre-service teachers an inquiry-based approach for a science classroom. To give context to the activity, I used my experiences as part of “High Arctic Change 2014” for a lab activity. As such, the activity focuses on discovering how glaciers are formed and flow and how icebergs float in water. The materials can
This lesson is based on studies completed by undergraduate geoscience students working around the glaciers of Kongsfjord, Svalbard during the summer of 2014. It is intended as part of a larger unit on matter that covers atomic theory, atomic structure and the periodic table. Students connect authentic research to their classroom understanding of atoms while learning how this
This lesson is based on studies completed by undergraduate geoscience students working around the glaciers of Kongsfjord, Svalbard during the summer of 2014. It is intended as part of a larger Earth science unit that covers erosion, transport and deposition of sediment. Students connect authentic research to classroom investigations while learning how to interpret current data to understand
