Background For Teachers:
This experiment will require about one month to complete. Plan accordingly. You may want to set up this activity at the outset of this unit and track its progress throughout the unit.

Leaves that fall to the ground begin to decay because of the actions of microorganisms in the soil. Rain provides the water that is needed to complete the chemical reactions. Fallen leaves turn dark and crumble because microorganisms are breaking down the larger chemicals in the leaves into simple materials that are released into the air and soil and can be used by other organisms.
In this experiment, the following changes will be observed:
