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
The long-term objective of PolarTREC teacher Lesley Urasky's expedition research in Antarctica (Glacial History in Antarctica) is to determine the rate at which glaciers have receded since the Last Glacial Maximum. This lesson is designed to give students an understanding of the Last Glacial Maximum, the climatic conditions that lead to glacial periods, and how the rate of glacial
The Antarctic Research Group at Boston University is lead by Dr. David Marchant. Graduate students include Adam Lewis, Doug Kowalewski, and Kate Swanger.
Marchant's ongoing NSF funded research projects focus on:
1. Age, origin, and climatic significance of buried ice in the Dry Valleys region, southern Victoria Land
2. Response of the East Antarctic Ice Sheet to middle Miocene global
