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.
Impacts of a field experience on teaching high school science
Early in my teaching career, I learned that authenticity is essential in creating working relationships with my high school students. By showing them that I am a human being with experiences, ideas, dreams, and opinions, I’m able to connect in ways that invite their attention as I teach skills
Emily Dodson-Snowden, a sixth-grade science teacher at Morton Middle School, didn’t have a typical summer break. She spent three weeks in Greenland studying how climate change influences plant/pollinator interactions and plant reproduction as part of PolarTREC (Teachers and Researchers Exploring and Collaborating).
