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.
