Explain to the children that some leaves change color in the fall, and ask if any of the
 children has ever seen red, orange, or yellow leaves.  Discuss the fact that only certain
 trees have leaves that change color and drop.  These are called "deciduous" trees.  Have
 the children slowly repeat the word deciduous.  Teach children the formula
 that turns leaves different colors:

Chlorophyll makes green leaves bright.
They stay that way from warm sunlight.
But in the fall there is less sun.
The leaves turn color, one by one.
They change to red, then gold, then brown,
Then they fall down onto the ground.
But in the spring, just wait and see,
All new green leaves will fill the tree.
