The Arctic Ocean Curriculum Unit was created by the Arctic Research Consortium of the United States with funding from the North Pacific Research Board. This project aimed to update and revise existing Arctic Ocean-related lesson plans originally created by PolarTREC program teacher alumni. The format used lends itself to the changes in education - providing student-facing slide decks that allow
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 lesson answers the question: How does ice floating on the ocean act as it melts?
Objective
* Students will learn about temperature, salinity and their effect on density.
* Students will learn that ocean currents are caused by differences in densities as a result of temperature and salinity. These differences allow ocean currents to circulate water
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
