PBS Learning Media: Life of A Tree

As stewards of the Earth’s trees, it’s helpful for us to know about the growth processes of trees, their role in the forest world, and how we humans can improve their quality. In this interactive activity adapted from the National Arbor Day Foundation, explore the intricate life of a tree. Begin with the protective bark on the outside, and then explore deep inside each layer to find out how the structure of each part affects its overall function in the tree. Then, by "reading" the tree's rings, learn how climate and other natural events affect a tree's growth.
