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
Permafrost puts extensive limitations on plant growth and building construction. Most students in the world are not exposed to this phenomenon and don’t have a clear concept of what it is or how it is at risk. This inquiry activity is designed to let them explore the impact of melting permafrost on a human structure.
The Surface Archaeology Activity will allow you to develop some of the knowledge and skills that archaeologists use to do their work while also getting a chore done at home. The steps are really easy, and then you can decide to maybe tackle another room in the house.
