This activity works best for students who don't have a lot of lab experience and learn best through hands on activities. It allows them to not only investigate an aspect of global warming (rising sea levels), they will also get practice with making predictions and writing a hypothesis as well as understanding basic scientific concepts such as water
This presentation is designed to supplement an eighth grade science unit on polar ice but could easily be used for other audiences. The presentation covers the differences between ice in the Arctic and Antarctica, how ice affects salinity, temperature and currents, an exploration of various ice types and a summary of current research efforts to study polar ice.
Jeanine Gelhaus
This lesson includes a variety of research activities and a lab that all help demonstrate the science behind convection currents.
Objectives
Through the following activities and lab students will discover:
* that temperature and salinity affect the density of fluids (liquids and gases)
* how fluids with different densities interact with each other
This video of the seafloor in Barrow Canyon, off the coast of Alaska is to accompany the presentation, 'The Arctic Ocean Ecosystem: Status and Trends in the Pacific Arctic' by Jacqueline Grebmeier, given during the 2012 Arctic Ocean Ecosystem Workshop.
Dr. Jacqueline Grebmeier presents her research on recent changes in the biology of the Pacific arctic ecosystem at the 2012 Arctic Ocean Ecosystem Workshop.
Dr. Lee Cooper presents his research at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska on arctic ocean processes and how these relate to oceans around the world.
This video shows divers investigating microscopic life forms living under the arctic sea ice. The video accompanies a presentation given by researcher Rolf Gradinger at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska.
This presentation, given by researcher Rolf Gradinger at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska, showcases the history and exploration of the unique and hidden microscopic life found under the Arctic Seas.
This presentation, given by Matt Druckenmiller at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska presents information on both the science and local knowledge of ice conditions off the coast of Alaska. His research considers whether a reduction or change in the variability of sea ice has an effect on the feeding patterns and thus body size of the
This video is to accompany the presentation, Shifting Prey in a Melting Arctic, by George Divoky, given during the 2012 Arctic Ocean Ecosystem Workshop.
