As a high school Chemistry teacher, you can use this set of computer-based tools to help you in teaching the chemistry of carbon and its compounds, the interaction of greenhouse gas molecules with electromagnetic radiation, and environmental chemistry.
This lesson plan allows students to visualize the molecular structure of atmospheric gases and to understand the effect of electromagnetic radiation on these molecules. The activity will also introduce the topic of greenhouse gases and their role in climate change. Thus, the use of this Lesson Plan allows you to integrate the teaching of a climate science topic with a core topic in Chemistry.
- 1. How do molecules of gases interact with electromagnetic radiation?
- 2. How do atmospheric carbon dioxide (CO2) molecules interact with infrared photons?
- 3. What is the greenhouse effect of Earth’s atmosphere?
- 4. Could an increase in methane emissions affect the Earth’s temperature? Why?
