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.

Materials in this kit, designed for 30 students, are reusable.

Various techniques are used to CROSSDATE wood samples to assure accurate dating.

To describe the regional climate..Less than 1% of the gases in Earth's atmosphere are called greenhouse gases.

Even though they are not very abundant, these greenhouse gases have a major effect.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.Includes 30 simulated tree cores (15 marked A and 15 marked X), a teachers guide, and 30 student worksheets and guides.kit #52 Students develop a basic knowledge of dendrochronology using the specially designed simulated tree cores in this engaging kit.The SKELETON PLOT is one method of crossdating tree rings.
