As a high school or undergraduate Geography, Earth Sciences, or Physics teacher, you can use this set of computer-based tools to help you in teaching about heat transport in the atmosphere, atmospheric circulation, and the Hadley Cell and Hadley Circulation.
Geography/Earth Sciences: The lesson plan also helps students to understand the effects of Hadley Circulation on global precipitation patterns, the geographical distribution of deserts, and trade winds.
Physics: The lesson plan also helps students to apply the law of conservation of angular momentum and understand the concept of a thermally direct cell.
Thus, the use of this lesson plan allows you to integrate the teaching of a climate science topic with a core topic in Geography, Earth Sciences, or Physics.
Use this lesson plan to help your students find answers to:
- How does the Hadley Cell transport heat in the atmosphere?
- Describe the geographical distribution of deserts. How does Hadley Circulation influence this distribution?
- What are the possible effects of climate change on Hadley Circulation?
- What might be the potential impacts of Hadley Cell expansion on Earth’s climate, global precipitation patterns, and the geographical distribution of deserts?
