In this online interactive, learners measure time using the growth rings of trees. This resource explains the meaning of growth and rest bands, the causes of variations in "tree calendars," and how dendrochronology is used by archaeologists to understand how wooden tools and structures were made long ago. Learners use a simulated increment borer to drill a hole in a tree, examine the rings, and create a tree calendar to date a piece of wood....
