Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

The carbon cycle isn't a bike which produces carbon and this lesson explains why. Through reading and discussion, groups of pupils create visual explanations of the four parts of the carbon dioxide oxygen cycle. Activities...

Seventy percent of the air pollution in China is due to car exhaust. Under the umbrella of environmental chemistry, learners extensively explore air pollution. From the makeup of our atmosphere to sources of major air pollutants, classes...

The fours stages of the carbon-oxygen cycle are described - photosynthesis, respiration, combustion, and decomposition.

Article explaining the importance of carbon as the basis for life, carbon dioxide's role in photosynthesis and respiration, carbon in the ocean and lithosphere, the impact of human activities on the carbon cycle, carbon that seems to be...

Learn about the element carbon and its importance on the Earth's atmosphere and sustainability of life on the planet. Additionally, understand the role the carbon cycle plays in global climate change over time.

Explains what the carbon cycle is and the basic steps in the cycle.

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

The importance of the carbon cycle, how it works, the sources of carbon, and the steps in the carbon cycle are explained here.

Outlines the steps for the movement of carbon along the carbon cycle through photosynthesis, food chains, being dissolved into the ocean, the decomposition of organisms, fossil fuel formation, industrial use of fossil fuels, carbon...

Complete illustrated discussion of energy flow within ecosystems, including discussions of trophic levels, ecological pyramids, food chains and webs, biological magnification, and cycles.
