Carbon Cycle

These links are provided to explain the carbon cycle. For information specifically on the carbon cycle's role in global climate change see also Global Climate Change Key Links

Global Carbon Cycle. Woods Hole Research Center. Short summary of the carbon cycle with good graphics and easy to understand information.

What is the Carbon Cycle? National Center for Atmospheric Research. Short, on-line classroom activity in which students explore the carbon cycle.

Carbon Trip through the Cycle. Utah State Office of Education. In this activity, students imagine themselves as a carbon atom and trace their journey through at least 4 steps of the carbon cycle returning themselves to the point of origin.

Carbon Dioxide Emissions. Utah State Office of Education. In this activity, students use balloons and background information concerning different country’s emissions to illustrate that different countries emit different amounts of carbon dioxide.

The Carbon Cycle. EPA Kids. Short, animated, online slide show explaining the carbon cycle and principal terms for elementary students.

Carbon Cycles, Teach Engineering-Resources For K12. Grades 6-8. Students are introduced to the concept of energy cycles by learning about the carbon cycle. Students will consider how human activities have disturbed the carbon cycle by emitting carbon dioxide into the atmosphere. They will discuss how engineers and scientists are working to reduce carbon dioxide emissions. Lastly, students will consider how they can help the world through simple energy conservation measures.

Dinosaur Breath, Teach Engineering-Resources For K12. Grades 6-8. 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 discover how the carbon cycle has been occurring for millions of years and is necessary for life on Earth.

The Carbon Cycle. Earth Observatory, NASA. Excellent source for information and graphics concerning the carbon cycle. Includes an introduction, biological and physical carbon, photosynthesis and respiration, carbon on the land and in the ocean, human role in carbon cycle, NASA missions to study the carbon cycle, and references.

The Earth's Carbon Cycle . Science Museum of the National Academy of Sciences. Short (3-page), easy-to-understand fact sheet about the carbon cycle, with definitions of the main long-term (sedimentation, etc.) and short-term (photosynthesis, etc.) processes involved in the cycle and an illustration that shows the ways human's add carbon to the cycle.

The Carbon Cycle, Past and Present. University of Colorado, Boulder, Department of Geological Sciences. Provides class notes for GEOL 3520, Environmental Issues in Geosciences, which are useful for understanding the carbon cycle. Includes graphics of the carbon cycle, quantitative estimates of carbon contributions from various sources, an easy to understand outline of carbon flux, notes on residence time, graphs on CO 2 in the past and today, and more.

Introduction to Climate Change. United Nations Environmental Program (UNEP). Provides 14 excellent graphics on the carbon cycle, planets and atmospheres, observed climate trends, impacts of climate change, temperatures and CO 2 curves, greenhouse effect, global atmospheric CO 2 and more. These images are free to use for educational purposes.

The Ocean and the Carbon Cycle. NASA Science. Good explanation of the ocean's role in the carbon cycle with good graphics.

Global Carbon Cycle. NOAA. This Global Carbon Cycle (GCC) program site offers a variety of technical information on oceanic carbon flux. The education section offers online videos and reports.
