I wanted them to understand that plankton not only feed the Arctic but that much of the world relies on these little critters that come to life for us when we look
This lesson answers the question: How does ice floating on the ocean act as it melts?
* 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.
