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.
Dayton's News Program, Fox 45 in the Morning, talks with teacher Chantelle Rose directly from the Arctic about her oceanographic PolarTREC expedition and follow-up involvement with the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska.
Students chose a research project, from one of seven suggested projects, to complete in class with a partner. Upon completion they will present their information to the class.
Objectives
Students will present a scientifically accurate project on a topic related to the PolarTREC Winter Sampling expedition.
Lesson Preparation
Introduce students to the PolarTREC website. Any expedition could be selected
Results from PolarTREC teacher Chantelle Rose's research cruise to the Bering, Chukchi and Beaufort seas surprise scientists and may have implications for climate modeling. Read more about the tenacity of life forms living off the coast of Alaska from this National Science Foundation press release.
Article about PolarTREC teacher Chantelle Rose's icebreaker-based expedition to collect some of the first winter information on the biology, chemistry, and physical oceanography of the Bering, Chukchi, and Beaufort Seas.
