Pollution and Aerosols
This is the second topic to cover about climate change in chemistry class. Again, due to being taught early in the semester, it requires additional background information for the students and perhaps an extra day or two of teaching.
Unit 2 chemistry topics:
- History of the atom and development of modern atomic theory
- Parts of an atom
- Isotopes, ions and neutral atoms
- Average atomic mass
- Basic structure of the periodic table
- Metals, metalloids and non-metals (properties, etc)
- Main families on the periodic table and their properties
Climate topics covered:
- Air pollution
§ Particulate matter
§ Ground-level ozone
§ Carbon monoxide
§ Nitrogen oxides
§ Sulfur oxides
§ Volatile organic compounds
o Health effects
o Pollution and climate change
o Reducing air pollution
- Aerosols
§ Dust
§ Sea salt
§ Sulfates
§ Black carbon
§ Organic matter
§ Nitrates
o Health effects
o Aerosols and climate change
o Reducing aerosol emissions
Bridge from chemistry to climate change:
- Discussion of different elements coming together to form compounds
- New properties created with the compounds
- Relate back to black carbon from previous week(s)
Teaching resources:
- Power point – Pollution and Aerosols
Student activities:
