Useful introduction to the carbon cycle with a diagram and a discussion of the effects of carbon dioxide on the greenhouse effect and global warming.

A comprehensive introduction to the carbon cycle. The cycle of atoms between living and non-living things is known as a biogeochemical cycle. The most common of these are the carbon and nitrogen cycles.

At this site from NASA you can understand how phytoplankton help the carbon dioxide levels between the oceans and the air stay in balance.

In this activity, students make Moebius strips and use them to demonstrate the interconnectedness of an environment. They will explore the natural cycles (water, oxygen/carbon dioxide, carbon, nitrogen) within the environment.

Through discussion and hands-on experimentation, students learn about the geological (ancient) carbon cycle. They investigate the role of dinosaurs in the carbon cycle and the eventual storage of carbon in the form of chalk. Students...
