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
Teacher Tim Dwyer discusses the Antarctica Treaty in conjunction with Antarctica Day 2016. He and Dr. Art Woods also discuss the research being done on Polar Gigantism on sea spiders based out of McMurdo Station.
In this investigation, students will measure production of CO2 from surface water and consider the role of surface waters in the global carbon cycle and climate change. They will gather data on using Vernier CO2 sensors. This lesson presents a wonderful opportunity for student-designed experiments.
This is a good lesson to get students thinking about the complexity of the systems involved in providing our society with energy, the consequences of energy use and efficiency. Students are encouraged to explore the data sets on their own, ask their own questions about energy use and present their findings to each other.
This 1-hour webinar was part of the C-ISE online course being offered by PolarTREC and the University of Alaska Fairbanks. The presentation theme was earth science, and discussed climate change in the arctic and how scientists are using glacial features to study arctic change. The presentation was conducted by PolarTREC Teacher, Mark Goldner, researcher Ross Powell, and Research Experience for
PolarConnect event with Mark Goldner, the Svalbard REU team, and Drs. Julie Brigham-Grette and Ross Powell working on marine and glacial science in Svalbard, Norway.
PolarConnect event with Mark Goldner and the REU students and PI's that are in Norway. Three REU students presented on their experiments. A good introduction to the research questions and the area.
