There's Something in the Air

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

Extensions

Encourage students to suggest variations of the investigation they just completed. For example, stand in front of a fan or other source of moving air while peeling the orange. Have students predict whether this variable (more rapid movement of air) will affect the distribution of orange scent throughout the room.

Mention that many kinds of gases and particles float in the air continually. Ask, What happens when things floating in the air get trapped inside a room? What if one of these pollutants is a harmful gas? and How can pollutants in air enter our bodies? 

Lead a class discussion about things we can do to prevent harmful substances (like dust, chemicals, or pollen) from building up inside our classrooms or homes.
