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.
Ice that forms in the polar oceans is an important driver behind the global climate. This ice is physically different from frozen precipitation in a number of different ways. In this brief inquiry activity, students make qualitative observations about two types of ice cubes and deduce ice composition based on their observations. This activity may serve as an introduction to
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
We are all teachers and students throughout our lives – even as adults we are students and even as children we are teachers. As adults, we are often afforded unusual opportunities to learn as we push ourselves in our interests and abilities. Through these opportunities—both expected and unexpected—our own understanding of what is possible expands as well as our desire
