Convection Connections

Science and Children—May 2001

Children are fascinated with large bodies of water, such as lakes and oceans. They feel the wind on their faces and observe lake and ocean water as it moves in waves. But do they know what makes the air and water move? The following two investigations will help upper elementary and middle school students better understand air and water movement, or convection currents. Although the activities aren’t new, they are uniquely presented within the context of the learning cycle (Marek and Cavallo 1997).
