This lesson will provide students with an opportunity to design and carry out an experiment that mimics the conditions causing accelerated ice melt along the face of the Thwaites Glacier off the southwest coast of Antarctica. Created by Sarah Slack during her expedition to Thwaites aboard the icebreaker Nathaniel B. Palmer, this activity aligns with the Science and Engineering
This lesson about the factors affecting water density in the Amundsen Sea was developed by educator Sarah Slack during her PolarTREC expedition aboard the Nathaniel B. Palmer icebreaker. Part of the science mission was to create a detailed map of the seafloor at the face of the Thwaites Glacier, which revealed a series of channels that were conducting a
PolarTREC (Teachers and Researchers Exploring and Collaborating) is a program funded by the National Science Foundation that partners K-12 teachers in the United States with scientists doing research in polar regions. The goal of the program is for teachers to be authentically integrated into scientific expeditions in order to gain new skills and experiences that they
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
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
