4. Insulators
A material in which electrons cannot move easily from place to place is called an insulator.
Examples of insulators are plastic, wood, and rubber.

5. What are Insulators?
Insulators are materials that do not allow heat to move easily through them.

6. What do Insulators help do?

7. Paper

8. Conductors
Materials that are conductors contain electrons that can move more easily in the material.
Examples: metals, iron, copper

9. What are Conductors?
Conductors are materials that allow heat to move easily through them.
