Plastics are polymers. What is the chemistry name for plastics?

There are many different polymers. Their properties determine how they are used. What determines how a polymer is used?

Do any of last lessons keywords apply to plastics?

Polymers can be flexible, cheap, electrical insulator, strong, tough resistant to chemicals and generally have a low density. Name four properties of some polymers.

Which material properties are the opposite of each other? Tough : Brittle Flexible : Brittle Conductor : Insulator

Composites are made up of more than type of material. What is a composite material?

Composites have a mixture of properties from the materials that make them up. Why are composites used?

Reinforced concrete is a composite of concrete (ceramic) and metal bars. Explain why reinforced concrete used for bridges?

Testing reinforced and not reinforced ceramic bars. https://www.youtube.com/watch?v=vuZcPTp51Zk
