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
This lesson answers the question: How does ice floating on the ocean act as it melts?
Objective
* Students will learn about temperature, salinity and their effect on density.
* Students will learn that ocean currents are caused by differences in densities as a result of temperature and salinity. These differences allow ocean currents to circulate water
Students will take some time and look at the PolarTREC website journals, pictures, and forums to learn about a certain teacher, researcher, or polar science expedition that has already taken place or is currently taking place. Students will use the attached worksheet to think more deeply about a polar researcher's job and work.
Compare what students in a tropical climate do to prepare for recess with students who live in the interior of Alaska. Learn several consequences caused by sub zero temperatures. Create awareness that people are able to prepare for a cold environment by adding layers of clothes.
