Gizmos: Circuit Builder (SOL 5.4ab)

Experiment: Drag each material into the gap in the open circuit. If the light bulb lights, the material is a conductor. If not, the material is an insulator. Organize these options into the right categories.

Groups:

(a) Conductors

,

(b) Insulators

• Conductor

• Are materials that do not allow electricity to flow easily through them.

• Insulator

• Are materials that allow electricity to easily flow through them.

• metals

• Example(s) of conductors include:

• rubber, wood, and plastics

• Example(s) of insulators include:
