Draw a picture of a tree with the different parts clearly delineated, or find a similar suitable image. This should include the tree's trunk, roots and crown. Make photocopies for all the children, plus have a few extra on hand just in case.
Show the children an image of a real tree, such as a photograph or projected slide, so that they have a real life association to what they are going to learn about. Ask the children where trees can be found. Accept or suggest answers such as in backyards, parks and forests.
Hand out the photocopies and pass out crayons to the children.
Tell them about the trunk of the tree, how it determines the tree's shape and serves as a platform for the top of the tree. Ask the children to color the trunk portion brown on their handout.
Tell them about the roots of the tree, how they give the tree stability by firmly holding it in place and absorb the water and minerals the tree needs to grow and live from the surrounding soil. Ask the children to color the roots portion brown on their handout.
Tell them about the crown of the tree, which consists of the branches and the leaves, and how the leaves of the tree collect energy from the sunlight and creates food for the tree. Ask the children to color the branches brown and the leaves green, if in spring and summer; red, yellow and orange if in fall or without leaves, if in the winter.
Ask the children to draw a forest of trees to accompany the first one on their handout. Other options include having them draw a park or a backyard with trees.
