- Educator could divide class into gas teams to explore each one of these scenarios, then report back to the rest of the class.
- Combine interactive with other resources on the site to support a deeper understanding of the content.
About the Science
- A simple informational interactive that describes the important properties and characteristics of carbon dioxide, oxygen, and ozone.
- Gives a cursory explanation of the greenhouse effect and elements of the carbon cycle.
- NOTE: The stated present level of CO2 is incorrect. For the current CO2 level see: http://www.esrl.noaa.gov/gmd/ccgg/trends/
- Comments from expert scientist: There is only little science in this presentation, which is probably appropriate for a broad audience. The comparison with Mars and Venus is good because it suggests that we understand quite well that CO2 is an important factor in setting the temperature. What's more, that suggestion reflects the truth. The last two illustrations ("where does O2 come from" and the "elixir of life") under "oxygen" are excellent.
