Everyday Objects and Material Resources
- Many everyday objects are made from material resources, such as:
- Utensils (knives, forks, spoons) made from metals found in rocks
- Furniture (tables, chairs, shelves) made from wood (oak, pine) or particleboard
- Plastics (beakers, bottles, trash cans) made from synthetic and organic materials (polymers) found in nature
- Glass (window panes, measuring jugs, light fixtures) made from silicon found in sand
Properties and Characteristics of Material Resources
- Metals are formed in distant stars, baked into the earth, and can be extracted, purified, and shaped using high temperatures.
- Wood comes from trees, which have been used by humans for tens of thousands of years.
- Plastics are synthetic and organic materials that can be bent and molded easily, made from various types of polymers (polyester, polypropylene, polyvinyl chloride, polyethylene).
- Glass is a transparent solid made from silicon found in sand, created by heating sand to high temperatures and shaping using a template.
