This one hour webinar is a great look at the PolarTREC 2014 Arctic expeditions. Each teacher presents a little about the research projects, implementation in the classroom, and outreach into communities.
Emily Dodson-Snowden, a sixth-grade science teacher at Morton Middle School, didn’t have a typical summer break. She spent three weeks in Greenland studying how climate change influences plant/pollinator interactions and plant reproduction as part of PolarTREC (Teachers and Researchers Exploring and Collaborating).
Density currents drive 3D movements within the world’s oceans that dwarf surface currents by volume. Density-driven movements due to temperature/salinity differences keep the world’s oceans well mixed & help to re-distribute heat from tropical areas towards polar areas. Resultant upwelling creates some of the world’s richest ocean ecosystems. Density movements known as turbidity currents are the world’s largest
