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.
The PolarTREC expedition places the teacher in the role of student. All aspects of the expedition ask the teacher to stretch her mind and reach beyond her comfort zone. This stretch presents itself to the teacher in having to learn new technology, new science, new presentation formats, and meet, live and collaborate with
Teaching science gives me the satisfaction of sharing my passion for the natural world with others. I try to create opportunities for students to experience science outside of the classroom much like I did in college, through local field trips, or even identifying and mapping out the various large landscape rocks scattered around
Data collected from experimental manipulations of ecological processes can help us understand the natural world, and perhaps even help scientists predict how complex systems may change. At CiPEHR, (Carbon in Permafrost Heating Experimental Research) located near Denali National Park, scientists have collected and analyzed seven years of data to learn how increases in soil temperatures influence the carbon
Attached is a resource for lessons and simulations that involve studying the Greenhouse Effect and how it affects temperature readings on our planet. The simulations created by PHET are incredible. https://phet.colorado.edu/ Aside from the Greenhouse Effect simulation in this lesson, this site has a large variety of resources for any grade levels to be used as lessons, labs
This lesson is a modification of what Dave Hess and I, Stan Skotnicki, use in our Earth Science classes at Cheektowaga Central High School. It is an extension of our lesson on Celestial Motions as we track the apparent path of the sun across the sky at different latitudes. Prior to this Lab activity they would have already
