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 engage in a hands-on activity to help them consider what students in a tropical climate do to prepare for recess compared with students who live in the interior of Alaska.
Objectives
Students will:
* Compare what students in a tropical climate do to prepare for recess with students who live in the interior of Alaska.
* Learn
Through activities, video observation, experimentation and the construction of a Remotely Operated Vehicle (ROV) students will learn about the chemical and physical properties of sea ice.
Objectives
Students will be able to answer main questions of where sea ice is, how it is formed, why the ice is important, how it is classified by indigenous people and scientists, how
The title of this lesson, 'Ssssno Seals' is a play on words. Will the ice seals survive? Yes or No? Paul Lukosi is a high school teacher in the lower Yukon River Delta, 6 miles from the Bering Sea...as the slough goes. The village he teaches in is heavily focused on family and culture, and has survived for thousands of
