About Air

The activity, "About Air," uses guided inquiry to teach students that air consists of varying amounts of several gases (nitrogen, oxygen, argon, and carbon dioxide), the most abundant of which is nitrogen. Students will use different colors of popcorn to model the composition of air. They will make predictions, measure, record observations, and draw conclusions based on their investigations. Specific science concepts addressed in this activity include the following.

  • Gases occupy space.
  • Air is a mixture of different gases.
  • Oxygen is needed by the body but is NOT the main component of air.
