This series of modules is designed to provide a basic understanding of wood as a raw material, and of principal products made of wood. What is the nature of wood? How do various types of wood differ? What properties do different kinds of wood have and why? How can wood properties be modified so as to improve performance? What are the limitations to wood use? What are the essential features that define their proper application and use? How are wood products measured and what units are used in commercial trade? The answers to these questions and more are included within this series.

These modules are designed to be studied in the order in which they are presented. However, frequent hot links to previous lessons and to a comprehensive glossary allow studying the modules in any order. Because of the same features, it is not essential that all of the modules be studied.

Each module includes a self-study quiz that tests understanding of key concepts. Instant feedback is provided, along with links to review material that is relevant to any question that may have answered incorrectly. Also included in the series are over 700 photographs and graphics, animations, and interactive exercises - all designed to promote understanding of the subject matter in an interactive environment.

This series is designed as a stand-alone sequence that provides the basics of wood science and technology. However, to gain the most from these modules, the study of them should be combined with reading of the book

    Haygreen, J.G. and Bowyer, J.L. 1996. Wood Science and Forest Products - An Introduction (3rd ed.). Ames: Iowa State University Press.

Several of the photos and graphics from this book are reproduced in the modules. The book, though, includes a level of detail that is not found in the modules and that will aid in understanding the subject matter. This series of modules, when combined with the Haygreen/Bowyer text, provide an exceptional introduction to the wood science and technology field. Recommended readings are outlined below:
