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
Students will conduct a demonstration that will help them gain a better understanding of the water cycle and runoff in a watershed. They will be able to replicate arctic and non-arctic watersheds by varying the size of the watershed. They will be able to visualize the difference in runoff by creating hydrographs of these different locations.
Students will investigate the breadth and depth of science taking place in the Polar Regions by reading and learning about one PolarTREC expedition and sharing it with the class.
Objectives
* To expose students to the wide variety of science happening in the Polar Regions
* To help students understand the process of science by examining one

In this one hour webinar, PolarTREC teacher Nick LaFave conducts professional development for teachers on his work at Toolik Field Station studying Predatory Spiders with researcher Amanda Koltz.
Meet PhD student Amanda Koltz and learn about what motivated her to study science and research spiders in arctic food webs. Her fun fact might surprise you!
This one hour event by Melissa Barker explains the research being done at Toolik Field Station, Alaska on nutrient transport in arctic watersheds. She is joined by team member Dr. Sarah Godsey.
Environmental Science teacher Nick LaFave will put his hands-on teaching and researching skills into service while participating in a study of wolf spiders and their impact on the arctic environment. Read more about his upcoming PolarTREC expedition in this article from his community newspaper.
