How is Soil Made?

Soil surrounds us and is part of our everyday lives but rarely do we take the time to observe and explore how it is created.  Our current experiments include creating models of the earth that allow us to observe weathering, decomposition, and how red worms help create soil.  We are also observing different natural resources such as sand, clay, and humus.  As you drive around San Antonio, try to pick out what natural resources you see in use.
