Air Movement in Pressure Systems

Activity Overview

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.

Objectives

  • 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.

Vocabulary

  • pressure
  • air
  • atmosphere
  • hemisphere
  • rotation
  • Westerlies
  • wind

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.
