This lesson was created by Rebecca Harris after being a part of the Arctic Glacial Lakes PolarTREC Expedition. She was inspired by how important suspended sediment, something so often overlooked by non scientists, was for developing paleoclimate models as well as ecosystems. Students will observe a watershed or a model of a watershed to make predictions about what might
This lesson plan was created by after being a part of the Arctic Glacial Lakes PolarTREC Expedition. I was inspired by the massive amount of data collected over the course of the research project and the complexity of hydrology in glaciated and non-glaciated basins in the Brooks Range of Alaska. Students will work together to make hypotheses about patterns
In August 2017, I spent two weeks at Lake Peters, in the Arctic National Wildlife Refuge. My team included Darrell Kaufman, project co-PI and Professor in the School of Earth Sciences & Environmental Sustainability, Ellie Broadman, graduate student and PolarTREC researcher, and graduate student Chris Benson, all of Northern Arizona University. Our research was part of the final
Teacher Rebecca Harris and Researcher Ellie Broadman discuss field work, weather and life at the remote field site near Lake Peters, Alaska as part of the Arctic Glacial Lakes Expedition. This live event was broadcast from Kaktovik, Alaska.
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
