As a resource for manufacturing and construction, wood has much to offer: it is renewable, beautiful, locally obtainable, and rather easy to machine. In addition to building products out of wood, wood can be scientifically studied in the classroom and lab. In the age of STEM integration, technology and engineering teachers can teach wood science, helping students to learn about experimentation and about connections among technology, engineering, mathematics, biology, chemistry, and physics. There is a distinction between wood technology and wood science. Ellis (cited in Barnes, 1979) clarified that wood science is "that body of knowledge applicable to wood as a material, including its origin, properties, and characteristics," whereas "wood technology follows as the application of knowledge in the conversion and processing of wood for use" (pp. 243-244). Both wood science and wood technology offer avenues for STEM integration, and in particular, for engaging students in scientific inquiry. Deliberate education in wood science can help students learn about the importance of using scientific information others have found. It also can help them learn to plan and conduct experiments and other scientific investigations. It is time for technology and engineering education to re-embrace wood science and what it has to offer students in the age of integrated STEM education. An appended "experiment brief" called "3D Printing Onto Wood" can be used to encourage student inquiry using a 3D printer and some samples of woods.
