Here are a collection of great activities to choose from.I would usually do the Power Point first and then do a simple "count the rings" lab.Thus, studying this variation leads to improved understanding of past environmental conditions and is the basis for many research applications of dendrochronology.A key distinction of dendrochronology is that all trees rings being analyzed are dated to their correct year of formation.This page does not attempt to cover the details of wood formation that make tree rings possible, but rather provides an overview of common wood characteristics and anomalies that you will need to identify when you are crossdating.
Grades 6-12Using the specially designed simulated tree cores, students will learn the important effects of climate on living things as they unravel secrets about the age and history of trees.
The practical applications of the study of tree rings are numerous.
Dendrochronology is an interdisciplinary science, and its theory and techniques can be applied to many applications. These research interests have in common the following objectives: Ring-counting does not ensure the accurate dating of each individual ring.
Two of them are incorrect and one of the NASA websites is not available anymore.
For a good alternative activity on dendrochronology see [link Signs of Change: Studying Tree Rings'] activity.
