This lesson plan is designed to teach students about the importance of the benthic community in the shallow portions of the Arctic and how climate change may affect their respiration. One of the dominant benthic animals in the Arctic, the bivalve Macoma sp., is an important food source for higher trophic level organisms such as walrus and Spectacled Eiders
This lesson plan is designed to teach students about benthic biodiversity in the Arctic by analyzing data from the Distributed Biological Observatory (DBO). Although you can’t see them from the surface, the organisms found on the ocean floor are important indicators of ecosystem health and provide information about productivity. Students will explore sites throughout the Bering and Chukchi Seas
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
The report is written by teacher participants upon return from their field expedition portion of the PolarTREC program. It summarizes the benefit of the expedition to the teacher, a description of activities, and a summary of how teachers plan to link this experience in classrooms and communities. This is a public document that will be posted in teacher portfolios and
