Labratory of Tree Ring Research

A Great FREE Field Trip at the University of Arizona



"The primary mission of the Laboratory of Tree-Ring Research is to remain in the forefront of world dendrochronology through the use of tree rings as natural chronometers and recorders of change in the environment with which human society is inescapably linked. The Laboratory makes significant contributions to understanding natural environmental variability in climatic, hydrologic, geomorphic, and ecological systems.
We are committed to promoting public awareness (and understanding) of science and making informal contributions to science education. As part of our Outreach program, we strive to inspire new connections and nurture existing connections among our community, which includes visitors to and residents of Tucson, and the K-12 educators and students communities."

The Teacher Version of the Field Trip:

Observe and Take Notes



Some vocabulary words and background information before the tour.

Tree ring diagram 

Petrified Wood


The tour begins in the lobby with these HUGE tree samples!




The building is a "tree house" and the branches (metal pipes) blow in the wind, 
but not for long...apparently they are very loud when your in the labs



Some REAL scientists at work :-) 


A long strip is cut out of the tree from the center out. 
Dendrochronologists can study the markings and rings from the radial slice.

More samples on the walls with great stories.
