We asked you to include carbon cycling in your Earth Systems Analysis diagram in the preceding session. Here are two activities that can be useful in teaching about the carbon cycle AND also about the human impact on this aspect of Earth's systems. The first gets students up and moving and the second is computer based. Read through them both and think about how might you use them with your students or visitors.

NOAA: The Incredible Carbon Journey (listed as grades 3-12). We have used this with middle school students through graduate students. 

Carbon Dioxide and the Carbon Cycle, a PBS Learning interactive (listed as grades 6-12). (Note that you may need a PBS Learning Media log-in to access this option.)

Then, check out this mesmerizing video that provides an overview of how carbon cycles in Earth's atmosphere over a year. What aspect of this visualization intrigues you the most?
