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 lesson focuses on adaptations as a driving force in evolutionary diversity. Adaptations are characteristics within a species that enhance its chances of survival and reproduction. Adaptations can be behavioral, structural, or functional. Students must understand that these adaptations are not acquired in the course of the organism’s lifetime, but are inherited traits that have been passed down
