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
Teacher Dave Jones and researcher Mike DeGrandpre present live from Montana discussing the research that took place for 4 weeks aboard the CCGS Louis S. St-Laurent looking at CO2 and pH Studies of the Arctic Ocean.
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.
In a “March Madness” game of survival of the fittest, will your microbe and its genes survive the test of changing conditions on Planet Earth and beyond? Students choose genes from a “toolbox” and pit their microbe against their classmates’, using critical thinking and argument writing to determine the microbe with the best chance of success. Based on PolarTREC
This one hour webinar is a great look at the PolarTREC 2014-5 Antarctic expeditions. Each teacher presents on the research projects, implementation in the classroom, and outreach into communities.
Analogs are used in science investigations to better understand systems we can’t access ourselves. In this lesson, students explore the Dry Valleys of Antarctica to better understand microbial communities on early Earth and what might have been possible on ancient Mars. Students will examine photographs, written descriptions, and artistic renderings of early Earth, the Dry Valley lakes, and
The report is written by teacher participants upon return from their field expedition portion of the PolarTREC program. It summarizes the benefit of the expedition to the teacher, a description of activities, and a summary of how teachers plan to link this experience in classrooms and communities. This is a public document that will be posted in teacher portfolios and
