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.
ScienceNews article highlighting the work of Polar Gigantism in Antarctica expedition Principal Investigator Dr. H. Arthur Woods on sea spider physiology.
Students will develop research questions that will help them develop an ecosystem profile (species/conditions etc.) of a local pond. Their results will be compared with data from the McMurdo Dry Valley Lakes in Antarctica. Discussions about climate and energy dynamics will be conducted as conclusions are drawn. A map and key for the local pond (species/locations/conditions) will be
