1. Wood is a natural material from trees. It is used in making paper, generating heat, building houses, bridges, and other buildings.  Wood can last hundreds or thousands of years. There are two types of woods, hardwoods and softwoods. Hardwoods come from broad-leaved trees and softwoods come from evergreen frees. Hardwoods have attractive grains and are used in making fine furniture and decorative woodwork. Softwoods are used for construction work. The inner structure of wood is anistropic because of its difference in annual-ring-and-grain structure. Its grain properties varies in different directions.

 2. Plastic PET (polyethylene terephthalate polyester) is often used in plastic bottle and toys. It is commonly used for its non-toxic, strong, lightweight, flexible material, and 100% recyclable. Unlike wood, the grain structure of wood is isotropic

3. Cotton comes from the cotton plant. It is used for yarns, fabric, clothing, blanket, napkins, cosmetic application, and etc. Its properties are comfortably soft, good absorbency, color retention, machine washable, good strength, drapes well, easy to sew together.  Cotton decomposes at temperature about 300 Fahrenheit. Cotton is harvested by machine and gets filtered by the cotton gin.
