Activity 76: Tree Cookies
One way to learn about tree growth is to look at annual rings. Tree rings show patterns of change in the tree’s life as well as changes in the area where it grows. In this activity, students will trace environmental and historical changes using a cross section of a tree, or “tree cookie.”
