Ice that forms in the polar oceans is an important driver behind the global climate. This ice is physically different from frozen precipitation in a number of different ways. In this brief inquiry activity, students make qualitative observations about two types of ice cubes and deduce ice composition based on their observations. This activity may serve as an introduction to
My high school has a Science Club whose members visit local elementary schools and run various “stations” that (elementary) students visit for 10-15 minutes before rotating to a different one. This lesson is designed to be one those – a quick hitting, but engaging look into polar science that will stir the kids’ inherent curiosity and get them
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
This video shows divers investigating microscopic life forms living under the arctic sea ice. The video accompanies a presentation given by researcher Rolf Gradinger at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska.
This video is to accompany the presentation, Shifting Prey in a Melting Arctic, by George Divoky, given during the 2012 Arctic Ocean Ecosystem Workshop.

View sequential still images of thermokarst (thawed permafrost) at Horn Lake in northern Alaska during the summer of 2010. The video was made by researchers studying the responses of Arctic landscapes to permafrost degradation.
The attached Lands and Life flyer, produced by the International Polar Year (IPY) Programme Office, includes a summary of terrestrial polar ecosystems, from southern cold maritime islands to dry continental deserts in Antarctica and from tree line across the continental tundra to remote northern islands in the Arctic. An attached activity allows students to build a small scale model of
Researchers at the University of Alaska Fairbanks are studying the East Siberian Arctic Shelf region and finding the seafloor there holds vast stores of frozen methane and is showing signs of instability and widespread venting of the powerful greenhouse gas. In this video University of Alaska Fairbanks scientist Natalia Shakhova discusses the East Siberian Arctic Shelf area.
In an explosive clip from the BBC's landmark series, scientists drill into a frozen lake to ignite methane gas that is trapped in bubbles beneath the surface. Do greenhouse gases pose a signficant threat to our planet? Dr Iain Stewart assesses the dangers.
