Mr. R.

**WOOD SAMPLE COLLECTION & NOTEBOOK**
	Option #2a - Collect and identify wood samples of 10 species of trees. List several ways the wood of each species can be used.
	"A Year in the Wonderful Trees" educates as to the importance of trees and their uses. The most common Types of Wood used to make furniture. Article taken from the Reader's digest about The Different Types of Wood. "Friends of the Earth" shows different types of wood timber from A to Z. There are literally hundreds of common and exotic types of wood. Look up a wood's common name, then see what is listed as common uses.

TREE RING PATTERNS

Option #2b - Find and examine three stumps, logs, or core samples that show variations in the growth rate of their ring patterns. In the field notebook you prepared for requirement 1, describe the location or origin of each example (including elevation, aspect, slope, and the position on the slope), and discuss possible reasons for the variations in growth rate. Photograph or sketch each example.

This is called the study of dendrochronology (the dating and study of annual rings in trees):

ology - the study of
chronos - time, or more specifically events in past time
dendros - using trees, or more specifically the growth rings of trees

Count the number of rings the best you can. Are they close together or far apart? Do they vary in size from year to year? Are there any unusual growth patterns (shifted to one side, part of the rings incomplete, etc.)?

Prepare a field notebook describing the location you found each tree and discuss possible reasons for any variations you see. You may wish to take photos of each tree ring pattern are make very good drawings, emphasizing any variations you see.

The Idaho Forest Products Commission's web site teaches about the different layers of a tree and get a basic understanding of tree rings. Learn about insects that destroy trees, how paper is made, take a Tree Trivia Quiz and more at the Kid's Site.
Microscopy UK has some GREAT tree ring photos.
