Prairie Plants and the Carbon Cycle

• Why are prairies important?

• How is carbon cycled in a prairie?
• Why is the carbon cycle important? 

Students could:

• Research and identify the concentrations of carbon in the hydrosphere, atmosphere, geosphere, and biosphere. 
• Develop a model (physical or drawing) that shows the cycling of carbon in different ecosystems. 
• Use a model to argue that matter is conserved as carbon cycles through the Earth's systems. 
• Debate the effectiveness of using models to explain the carbon cycle. 

• National Center for Atmospheric Research and UCAR Office of Program | Living in the Greenhouse:  This resource shows a carbon cycle graphic and explains what happens in the carbon cycle. 
• National Oceanic and Atmospheric Administration (NOAA) | Carbon Cycle: This site describes the carbon cycle on different areas of the Earth as well as changes that have happened to the carbon cycle.  
• National Oceanic and Atmospheric Administration (NOAA) | Global Greenhouse Gas Reference Network: Explore different observatories and what they are looking for in regards to greenhouse gases.   
• NASA | Earth Observatory:  This resource explains where carbon comes from and what the carbon cycle's impact is on the atmosphere. 
• BBC Bitesize | Material Cycling in Ecosystems: Learn about the carbon cycle and the components that have a part in the carbon cycle. 
• Woods Hole Oceanographic Institution | Carbon Cycle: This resource from Woods Hole Oceanographic briefly describes the carbon cycle and gives links to different news releases about the carbon and the carbon cycle.
