I know about trees- they are all around me, and they are the biggest plants in the world. What else do I know about trees? Wood comes from trees, and my chair and my pencil are made of wood. The rubber at the end of my pencil comes from trees. Birds make nests in trees and insects live in them too. Trees have leaves that come in all sorts of shapes and sizes. A lot of food I eat, such as fruit and nuts, grows on trees. The activities included are- making bark and leaf rubbings, and learning to measure how tall a tree is.
