Convection Connectionsby: Ann M. L. Cavallo

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).

The authors describe how to take simple traditional experiments on how air and water move (convect) when heated or cooled and put them together to inspire children to develop their own investigations. Moving from direct instruction to inquiry using a 3-step learning cycle, the authors guide students to develop the concept of convection and briefly describe the assessment. I would have liked to know more about the assessment, but I think that different levels would do it in different ways, anyway. Very clever lesson and I can't wait to try this with my classes
