The purpose of this resource is to show how graphs of GLOBE data over time show the interconnectedness of Earth's system components at the local level. Students visit a study site, where they observe and recall their existing knowledge of air, water, soil, and living things to make a list of interconnections among the four Earth system components. They make predictions about the effects of a change ... Full description.

The purpose of this resource is to introduce the different particle sizes of soils and the properties which each contributes to the soil character. Students make mud pies by adding water to the various soil components, letting them dry and observing the pie's characteristics. Students sift soil to remove organic materials and pebbles. They then sift the soil with smaller meshed sieves to separate ... Full description.

The purpose of this resource is to familiarize students with the importance of perspective and various scales of remotely sensed data. Students create a 3-D model of an area and develop a classification system for the landforms in their model. The maps can then be used to answer certain questions about the environment.
