Introduction: Watch Chemistry, Valence Electrons.
Write out the electron configuration of an atom from each group (include the condensed version as well). Which electrons in the completed configurations will be used first in a chemical reaction? Why?
Understanding Valence Electron's Role in Greenhouse Gases
1. Take the Greenhouse Gases assessment.
2. In teams of two scan through the reading: Climate Change in the Golden State.
3. With a highlighter, circle the sources mentioned and underline the sinks of each gas. In the margins point out the human sources of each as well.
4. Share these with the class & take notes.
5. Correct your assessments.
What are the main greenhouse gases?
In teams: Choose a focus gas, model it and discuss everything you've learned so far about it chemically. Be ready to share with the class.
Extension: In the Greenhouse Gases Overview, draw and color code each molecule, show their molecular shapes, bond angles and formulas for the gases.
Discuss how the valence electrons are distributed for your group's molecule. Answer the following:
1. Which molecule(s) have the biggest effect on global warming?
2. Which molecule(s) are the most abundant?
3. Which keep increasing in abundance as global temperatures increase?
