Small groups 7. Have them follow the directions and observe what happens. The temperature will not change as much when white paper is used because the heat is not retained as well as with the black paper. Have students relate this experiment to what they now know about Antarctica. Tell students that Antarctica would be even colder if it were not for the air currents arriving from other parts of the world.
Warm air rises.
When air is heated by the sun at the equator, it rises and moves toward the poles. Students should utilize the internet, almanacs, and other sources for this activity. Students should record their findings on the Comparison worksheet and compare them with the findings of other students. Tell students that Antarctica is also the windiest place on earth. Ask students if they have ever heard of wind chill.
