Forestry: Tree Biology And Wood Properties Exploration.pdf

This educational unit, designed for grades K-12, explores the diverse aspects of forestry through interactive exercises. It is part of the Biology in a Box program, a collaboration between The University of Tennessee and the National Institute for Mathematical and Biological Synthesis.

Materials:
The unit includes various materials such as posters (Tree Parts, Trunk Parts), cards ("Missing Parts," "Wood Chips," "Critter/Habitat"), puzzles, measuring tools, tree cookies, leaves, seed cases, wood density cubes, a digital scale, magnifying glasses, and forest-related products.
