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
Students will use the TAMMNET project and accompanying PolarTREC resources to learn about seismology in the Antarctic, culminating in the creation of an annotated map using google maps.
Objective:
Students will understand the different ways mountain ranges are formed, and appreciate the questions unanswered about the Transantarctic Mountains. Students will also appreciate the ingenuity required for doing research in
Students will conduct a demonstration that will help them gain a better understanding of the water cycle and runoff in a watershed. They will be able to replicate arctic and non-arctic watersheds by varying the size of the watershed. They will be able to visualize the difference in runoff by creating hydrographs of these different locations.
The Dry Valleys region in Antarctica is known as the coldest, windiest, driest place on Earth. Beacon Valley is famous for its katabatic winds which can routinely knock fit adults and PolarTREC teachers to the ground. This lesson was created by PolarTREC teacher Jacquelyn Hams who experienced the cold and the full force of the winds in 2008
