Fourth graders explore tree rings. In this plant biology lesson, 4th graders construct a KWL chart on tree rings and examine real tree rings. Students identify the changes that happened during the tree's life and its actual age. Students...

Young scholars examine tree rings to determine its age.  In this tree ring lesson, students examine core tree samples, identify the tree rings, and then determine its age. Young scholars complete a worksheet, deciding which of the...

Students complete activity sheets and participate in discussions while they study dendrochronology. They determine a tree's age and recognize how the climate varied over time.

Students examine how scientists determine the age of living and non-living trees. They simulate the role of a tree-ring scientist, crossdating tree-ring samples and determining which sample is the oldest and the age of the samples.

Students investigate the age of trees by analyzing tree rings.  In this dendocronology lesson, students examine sample images of tree rings and identify their age by the amount of rings.  Students complete a chart identifying...

Learners investigate their family heritage and plot their timeline.  In this research lesson students study their family tree and forestry. 

High schoolers work in pairs to determine the age of a tree using two different methods in this experiment. They collect data about how trees change over time.

Students create a timeline that explains how ancient cultures used artifacts. In this Relative Dating in Archaeology lesson, students examine artifacts and draw conclusions about their origins. Then students analyze antiquated objects or...

Middle schoolers study cross sections of trees or tree "cookies" to discover how the rings on tree sections give clues to the climate during the time the ring was produced. They study simulated cross sections of trees to determine the...

This is a set of lessons where young scholars investigate tree rings and what scientists can learn from them. They measure tree rings and correlate the data to precipitation patterns in order to make predictions about the climate. For an...

Examine how scientists determine the age of living and non-living trees and identify factors that impact sizes of tree rings. Analyze tree ring samples and determine the age of the oldest sample.
