PolarTREC teacher Andrea Skloss’ lesson was inspired by her Chukchi Sea Ecosystem Study aboard the USCGC Healy. In order to understand why this area is a biological hot spot of productivity, scientists must study components such as the trophic levels and more.
Objectives
In organisms and environments, the student knows that interdependence occurs among living systems and the environment
There is so much media hype and public misunderstanding regarding the issue of climate change that advanced students need to be equipped to sort through the information available, find data from appropriately moderated scientific data bases, and learn to support their views with good scientific evidence rather than emotion. This lesson provides the outline for giving students some preliminary
How can the ocean be colder than 0 degrees C, the temperature at which water freezes? As it turns out, the concentration of the particles (in this case, the ions from the salt) in ocean water lowers the temperature at which the saltwater will freeze. Students will learn how ocean water freezes at a lower temperature than freshwater by
