What are Materials?
That’s easy! Look around.
Our clothes are made of materials, our homes are made of materials - mostly manufactured. Glass windows, vinyl siding, metal silverware, ceramic dishes…
Most things are made from many different kinds of materials.
Kinds of Materials Metals: are materials that are normally
combinations of "metallic elements". Metals are quite strong but malleable and tend to have a lustrous look when polished.
Ceramics: are generally compounds between metallic and nonmetallic elements. They are insulating and resistant to high temperatures and harsh environments.
Kinds of Materials
Plastics: (or polymers) are generally organic compounds based upon carbon and hydrogen. They are very large molecular structures.
Semiconductors: have electrical properties intermediate between metallic conductors and ceramic insulators.
