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.
Humans hold special relationships with the natural resources by which they are surrounded. These connections are increasingly being challenged by changing climate patterns, availability of resources, and societal changes. In this activity students will investigate the cultural importance of an Arctic plant or animal. Each student will create a carving and research traditional uses, geographic range, and natural history
Elizabeth Eubanks M.Ed (working with Angela Gilmour, Anne Jensen, Danielle Dickson, Leslie Pierce, and Rachel Potter) connected with PolarTREC and NOAA TAS. This lesson is inspired by the need to share the importance of the Bowhead Whale in relation to the culture of arctic people. It is a portion of an entire collaborative unit to be utilized between
This engaging topic and active game is inspired by a long-term scientific study of Black Guillemots nesting on an island near Barrow, AK. It introduces the life cycle of the Black Guillemot, how it raises its young, and the adaptations it is making to adjust to life in a changing Arctic.
This lesson introduces students to krill, their importance in ocean ecosystems, and the physical structures that make up the krill body. The students will then use the principles of a "floater" species and design their own krill, hopefully having a class competition to see who can build a better krill.
Objectives
Students will understand the importance of krill in
Rings of life is a comparative lesson allowing students to investigate growth rings in walleye Pollock from the Bering Sea and Ponderosa Pine trees.
Objectives
Students will be able to compare and contrast growth rings on fish and trees, showing just one of the tools scientists use to monitor the health of different ecosystems. Students will also be able
