This lesson focuses on the diffusion of gas molecules across the cuticle membrane of sea spider legs and the role body size plays in the ability of sea spiders to uptake gases. Students construct model sea spider legs of varying diameters and use them to investigate the relationship between surface area-to-volume ratios and diffusion.
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
ANDRILL (ANtarctic geological DRILLing) has drilled and recovered thousands of meters of rock core from beneath the McMurdo Ice Shelf in Antarctica. What secrets are hidden in this rock? Why do scientists from around the world work together to uncover these secrets that have been shrouded beneath the ice for millions of years? Join this real world geoscience adventure in
The Polar Resource Book - Polar Science and Global Climate: An International Resource for Education & Outreach - was written to ensure that the efforts catalyzed by the International Polar Year (IPY) will continue to inspire educators, students, and emerging polar researchers with a shared commitment to outreach and education.
This 250 page book edited by Bettina Kaiser and others
Icy IPY activities can be downloaded in word documents and tried in your classroom. From 'Blubber Gloves' to 'Experiments with Ice and Snow', there are a wealth of different activities to introduce students to the Polar Regions or complement their existing knowledge of the Poles.
The International Polar Year is a large international effort that has involved over 200 projects
Share in the excitement of unearthing a biface and other archaeological treasures, as Alaskan researchers explain how they discover and document early human settlement sites across arctic Alaska. This video is part of a larger story on the Frontier Scientists website (http://frontierscientists.com/), the University of Alaska Fairbanks' portal for sharing the Arctic's newest discoveries.
Travel back in time as scientists and PolarTREC teacher Karl Horeis take you out to their dig sites to uncover hidden clues about early human settlement in arctic Alaska. This video is part of a larger story on the Frontier Scientists website (http://frontierscientists.com/), the University of Alaska Fairbanks' portal for sharing the Arctic's newest discoveries.
All About Glaciers is a web site produced by the National Snow and Ice Data Center (NSIDC) with information on all aspects of glaciers including data and science, facts, a gallery, a glossary and more.
I, Elizabeth Eubanks PolarTREC teacher 2008 – Arctic Tundra Dynamics created this lesson to introduce my students to utilizing technology to document and share what they know, want to know and have learned about polar studies and environments.
Objective
The objective of this lesson is for students to utilize recording devices (audio with or without video) and
