Photosynthesis, Respiration, and the Carbon Cycle
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 - What are its Implications for Climate Policy?
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...

Volcanos and the Atmosphere
In the summer of 1815, snow fell every month in New England. Was this related to the volcanic eruption of Tambora in Indonesia earlier in the year? Young scientists design their own experiments to research the long-term effect a volcanic...

Windows to the Universe: Biogeochemical Cycles
Biogeochemical cycles happen when individual elements are recycled over and over in different parts of the Earth. Two examples are the Nitrogen Cycle and Carbon Cycle. Read an explanation of biogeochemical cycles and view a diagram of...

College of Du Page: Energy in an Ecosystem
Ecosystems contain two kinds of commodities: matter (nutrients) and energy. Nutrients cycle through the ecosystem, available for repeated use by organisms. These cycles of use and reuse are called biogeochemical cycles. Energy instead is...
