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
PolarTREC teacher Jillian Worssam was one of a handful of teachers singled out by the Rodel Foundation of Arizona as an exemplary teacher. This article gives a sneak peak into Ms. Worssam's very hands-on, field-based classroom and how she connects with her middle school students.
Rings of life is a comparative lesson allowing students to investigate growth rings in walleye Pollock from the Bering Sea and Ponderosa Pine trees.
Objectives
Students will be able to compare and contrast growth rings on fish and trees, showing just one of the tools scientists use to monitor the health of different ecosystems. Students will also be able
The following PowerPoint presentation is part of an anticipatory set used to excite and introduce students to the many wonders of the Bering Sea. The PowerPoint is to be presented at the beginning of a unit about the Bering Sea.
Objectives
At the start of a unit on the Bering Sea this PowerPoint video presentation will engage
Students will develop an understanding of what it takes to interview scientists, and take the corresponding data and reformat it into an electronic medium.
Objective
Students will be able to write questions to scientists in the field, interview, take the data collected, and convert to an electronic format including MP3 clips and post to the Internet.
