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.
Soil decomposers, such as some bacteria and fungi, obtain energy needed for life from dead and decomposing plant and animal remains, known as soil organic matter. Soil organic matter is important to local ecosystems because it affects soil structure, regulates soil moisture and temperature, and provides energy and nutrients to soil organisms. It is also important globally, because
Students in cooperative teams will use a spreadsheet and graphing program such as Google Sheets or Microsoft Excel to graph and evaluate a large data set. The data sets provided come from authentic arctic ground squirrel research completed at Toolik Research station in arctic Alaska. The data sets were downloaded from body temperature loggers implanted into individual animals

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
Just as the increase in atmospheric CO2 is causing the global air temperture to rise, the container with the added CO2 will trap more heat inside and will show a higher internal temperature.
Overview
This activity/demonstration can be used directly following lessons on greenhouse gasses and their effects on warming the atmosphere by allowing shortwave UV energy
