Melissa Lau spent a month in the tundra ecosystem gathering data using a device called a Greenseeker. This device measures exactly how green a plant is by calculating its NDVI or Normalized Difference Vegetation Index. In this lesson, students will explore light waves, how they interact with plants, and find out how green is green.
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
This 1 hour webinar celebrates Antarctica Day 2015 with PolarTREC teacher Michelle Brown and the Human Impacts in Antarctica 2015 expedition. Michelle and her team are on the ice, at McMurdo Station, sharing their research project with the webinar audience.
This one hour webinar features Alex Eilers and the team studying Weddell Seals in the Ross Sea. The team shares their research with the audience and honors the importance of Antarctica Day. The event celebrates the international treaty stating that Antarctica is set aside for peaceful scientific purposes.
This is a one hour webinar hosted by PolarTREC teacher Andre Wille at Toolik Field Station, Alaska. The work presented is part of the Arctic Ground Squirrel Study 2014.
