Lesson One: Introduction
Provides course learning objectives, student expectations, available resources, and explanation of the structured online learning format.
Lesson Two: Structure of Woods
Wood is a unique building material as it is a once-living substance. This gives it properties no other building material contends with.
3. Lesson Three: Characteristics of Woods
The living characteristics of wood fuse with lumber cuts to create unique grain patterns.
Lesson Four: Beautiful Woods
Let's take a look at a sampler of beautiful woods you may one day work with.
This is the end of course quiz.

Optional learning; These videos showcase advanced woodworking skills used in building one-of-a-kind furniture pieces. You will have mastered these skills by completion of your woodworking program.
Heartwood vs Sapwood
In both softwoods and hardwoods, the wood in the trunk of the tree is typically divided into two zones, each of which serves important functions distinct from the other. The band of lighter colored wood adjacent to the bark is called sapwood. Heartwood is the darker colored wood found in the interior of the tree, at it’s core.
See the descriptions of each zone of a tree.
Living cells of the sapwood are also the agents of heartwood formation. Biochemicals must be actively synthesized and translocated by living cells. For this reason, living cells at the border between heartwood and sapwood are responsible for the formation and deposition of heartwood chemicals, one important step leading to heartwood formation.
