Moving Air

Author(s): Nancy Moreno, PhD, Barbara Tharp, MS, and Judith Dresden, MS.

How Does Air Behave?

Focus students’ attention by asking, Is it hot or cold outside? and Do you know that the temperature of air affects how it behaves and what it can do? Explain that temperature affects how fast air molecules move and how much space air takes up. You may wish to stimulate further conversation by asking, Can you think of any other ways temperature changes the way air behaves? 

Have students predict whether air will sink or rise if it is warmed. Write their predictions on the board, and then ask, Have you ever wondered how hot air balloons fly?
