Introduce the soil color book . First, conduct a quick poll on how many soil colors there are. Wow, were they surprised. Explain how soil color can change and how parent material can be a big factor just like their parents are the factor in their color. Sometimes you just don't feel well.
Texture fits in perfectly here.
I used the standard examples to explain the different textures. This idea led into the smell of a good soil. Several samples were passed around and the differences were easily noticed. The discussion then went into the idea of what goes into a soil. From here we went into a brief discussion of what they do to feel better and what we can do to make to the soil feel better.
