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.
Biodiversity is a central concept in understanding ecosystem functioning. Students explore how biodiversity is measured, impacted and can shift due to environmental changes to develop their understanding. Based off of the Microbial biogeography studies that Dr. Byron Crump is doing in the Arctic and around the world.
