There's Something in the Air

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

There’s Something in the Air

In this activity, students will compare the dispersal of odors indoors and outdoors as a model for the movement of pollutants in indoor and outdoor air. Students will discover that although odors often disperse in the air outside, they can become concentrated in indoor environments. Students will make predictions and observations, record and compare data, and draw conclusions based on their investigation. 

Science concepts addressed in this activity include the following.

  • Many kinds of gases and particles travel through, and become dispersed in air.
  • Substances in air become concentrated in enclosed spaces.
