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.
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.
Follow the Polar Expedition is a booklet designed for students to help them learn about the 2012 Chukchi Sea Offshort Monitoring in the Drilling Area (COMIDA) Hanna Shoal Ecosystem Study with PolarTREC teacher Deanna Wheeler. The expedition is August 5-25, 2012, aboard the U.S. Coast Guard Cutter.
The booklet has terms used on the ship as well as several activities
Plan and run a family fun afternoon or evening with several hands-on activities. Students help run the activity stations and share what they have learned about the Polar Regions. A great culminating activity for a unit on the Arctic, Antarctica, or both, and a fun way to involve families in the learning experience.
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
We all know that Antarctica is a very cold place, and the scientists who work there are not the only ones who have to worry about staying warm. The animals that live in Antarctica have to protect themselves from the frigid conditions on a year-round basis. In order to keep heat they produce from escaping into the environment
