Trees play a vital role in our environment and daily lives, offering numerous benefits that often go unnoticed. This exploration dives into the importance of trees and their various components, from roots to leaves. Participants will discover the fascinating field of dendrochronology, which uses tree rings to uncover environmental history. By examining tree slices, known as “cookies,” participants will gain hands-on experience in reading the story of a tree’s life and the climate conditions it experienced. This engaging journey through the world of trees not only highlights their ecological significance but also provides a tangible connection to the past through the study of tree rings. Participants will be able to keep their tree “cookie.”
