Dendrochronology: Tree Ring Dating Kit

Students develop a basic knowledge of dendrochronology using the specially designed simulated (artificial) tree cores in this engaging kit. Students will learn how to determine age and climate of trees and develop a greater understanding of tree-ring dating principles using these activities. Your students will learn the important effects of climate on living things as they unravel secrets about the age and history of trees. They will also be asked to estimate the climate of a particular year in the distant past by carefully studying a tree's annual rings. Students can also infer similar information by using various wooden objects.

This kit uses highly motivating, easily performed activities. It is recommended for grades 5+. Materials in this kit, designed for 30 students, are reusable. Following a carefully designed lab activity using two different tree core samples, the student will:

• Determine the age of the trees
• Compare wet and dry years and attempt to relate them to chronological events in their lives
• Attempt to establish the year when a piece of lumber was cut and when it started growing
• Develop a better understanding of tree-ring dating principles

Includes two sets of 12 tree cores to examine, plus a teacher's guide.
