Incomplete - CO2: That Pesky Gas

Summary

Discuss properties, and how properties make it easier / harder to separate materials. CO2 has properties that make it stay in the atmosphere for a long time.

Discuss the flow of CO2 into and out of the atmosphere. Note that manmade CO2 emissions are relatively small, but cause the system to be out of balance -- more CO2 is entering the atmosphere each year than is leaving.

Relate the flow of carbon to the flow of energy using the photosynthesis or respiration reaction.
