Students can also infer similar information by using various wooden objects.This Lab-Aid uses highly motivating, easily performed activities. Materials in this kit, designed for 30 students, are reusable.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.As a tree physiologist I would say that evidence of false rings in surely counts much more strongly against such the notion. Considering that the immediate post-Flood world would have been wetter with less contrasting seasons until the Ice Age waned (see Q&A: Ice Age), many extra growth rings would have been produced in the Bristlecone pines (even though extra rings are not produced today because of the seasonal extremes).Creationists have shown that the biblical kind is usually larger than the ‘species’ and in many cases even larger than the ’genus’—see my article Ligers and wholphins? Taking this into account would bring the age of the oldest living Bristlecone Pine into the post-Flood era.

The extended tree ring chronologies are far from absolute, in spite of the popular hype.The biggest problem with the process is that ring patterns are not unique.There are many points in a given sequence where a sequence from a new piece of wood matches well (note that even two trees growing next to each other will not have recognized that ring pattern matches are not unique.He'll also learn a bit about a tree's inner layers, and then he can take a quick quiz when he's done.kit #52 Students develop a basic knowledge of dendrochronology using the specially designed simulated tree cores in this engaging kit.
