Wood Composition

Roots help anchor trees and prevent soil erosion.

• Tree roots are essential for maintaining soil stability and preventing erosion.

• Tree roots primarily absorb water and nutrients from the soil.

• Tree roots are mainly responsible for photosynthesis in trees.

• Tree roots do not play a significant role in soil stability.

Tree rings

• indicate the age of a tree and the conditions it has experienced.

• are formed only during the winter months.

• are used to measure the height of a tree.

• indicate the type of soil a tree grows in.

Spring Growth characteristics

• Grows slowly, small cells, cells tightly packed, dark in color, harder

• Grows quickly, large cells, cells spread out, light in color, softer

• Grows at a moderate pace, medium cells, cells somewhat spread out, medium in color, medium hardness

• Grows quickly, small cells, cells tightly packed, light in color, softer

How does wood glue work?

• Wood glue forms a bond by melting the wood fibers together.

• Wood glue needs time and pressure (clamps); goes into cells of wood and forms resin, will be stronger than the wood itself if used correctly.

• Wood glue works by creating a chemical reaction that hardens when exposed to air.

• Wood glue is effective only on softwoods and not on hardwoods.

What category of tree has needles?

• Deciduous trees

• Coniferous trees

• Fruit trees

• Palm trees

Diagram of Quarter Cut Wood

• Illustration of quarter cut wood highlighting the distribution of wasted and usable wood.

• A representation of the different types of wood cuts available.

• A chart showing the benefits of using quarter cut wood over other types.

• An image depicting the process of cutting wood into quarters.

Types of Cuts: Plain Cut/Flat Sawn

• Most efficient cut with wide open grains

• Least efficient cut with narrow grains

• Cut that produces the most waste

• Cut that is best for structural strength

Summer Growth characteristics

• Grows quickly, large cells, cells are loose, light in color, softer

• Grows slowly, small cells, cells are compact, dark in color, harder

• Grows at a moderate pace, medium cells, cells are irregular, medium in color, average hardness

• Grows rapidly, large cells, cells are spread out, bright in color, very soft

Saw mill steps: Step 2

• Cut off a slab to provide a flat spot to lay log on

• Cut the log into smaller pieces for easier handling

• Remove the bark from the log

• Stack the logs for drying
