This is a short NASA video on the water cycle. The video shows the importance of the water cycle to nearly every natural process on Earth and illustrates how tightly coupled the water cycle is to climate.

This series of activities introduce students to polar oceanography, polar climate and how events that occur in oceans thousands of kilometers away affect them and the mid-latitudes using maps, images, lab experiments and online data tools. Students explore how conditions are changing in the Polar Regions and the possible impacts upon life in the United States and other mid-latitude nations.
