You can join in the tree study by taking your child for walks in your neighborhood to observe trees and other plants and to compare how they are alike and how they are different. For example, see if you can find two trees of the same kind. How were you able to tell they were the same kind? Which trees lose their leaves in the fall and which keep them all year? Look closely at the leaves. What shape are they? Do the trees have buds, flowers, fruit, or seeds? By making this close examination of trees, you might notice things about trees that you never thought about before.
