Geochemical Cycles (9-12) * The earth is a system containing a fixed amount of each stable atom or element. Each element can exist in several different chemical reservoirs. Each element on earth moves among reservoirs in the solid earth, oceans, atmosphere, and organisms as part of geochemical cycles. * Movement of matter between reservoirs is driven by the earth's internal and external sources of energy. (NSES, 1996)

The name of this wonderful web suite of learning tools is called the Water Cycle. This incredibly well designed science resource is divided into four sections: 1) Lesson, 2) Global Impact, 3) Explore, and Activities. Make sure that you visit all of them. This learning tool is from one of the leaders in science education the National Oceanic and Atmospheric Administration (NOAA). Their clear vision and exciting design help students learn science in innovative ways. |

The name of this "learning tool" is called An Element on the Move and traces the sources and processes of the carbon cycle. The aim of this activity is to help you understand the global carbon cycle by exploring it through an interactive model. This learning tool is found in the interactive zone of the Open University. A great site! |
