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
This mini exhibit explores the science behind climate change and introduces current climate change research to the public. Panels cover the topics of changing climate, ocean acidification and sea level rise, giving examples of how data is collected and current research in these fields. The exhibit also provides websites for further exploring climate change impacts.
This one hour webinar is hosted by Dominique Richardson and the team studying the Antarctic Ice Stream Dynamics was a special event to celebrate Earth Day 2015.
This one hour webinar features Alex Eilers and the team studying Weddell Seals in the Ross Sea. The team shares their research with the audience and honors the importance of Antarctica Day. The event celebrates the international treaty stating that Antarctica is set aside for peaceful scientific purposes.
