Earth Science: Air Movement in Pressure Systems

by Texas Instruments - Simulation Lesson


  • Students will observe the effect of the earth’s rotation on wind direction in the northern and southern hemispheres.
  • Students will understand how air movement relates to pressure systems in the atmosphere.

About the Lesson

In this lesson, students will observe air movement in high and low pressure systems. Students will use observations to determine wind direction in a specific region and recognize how the rotation of the earth affects air circulation.

 As a result, students will:

  • Understand that wind direction is a result of pressure differences.
  • Understand that the rotation of the earth causes winds to curve inward or outward from a pressure system.
