Insulators vs Conductors for 5th Grade

What is the main difference between insulators and conductors?

• Insulators do not allow the flow of electricity, while conductors allow the flow of electricity.

• Insulators are used for conducting electricity, while conductors are used for insulation.

• Insulators and conductors have the same properties.

• Insulators allow the flow of electricity, while conductors do not.

Name a common example of an insulator.

• plastic

• metal

• rubber

• glass

Which materials are good conductors of electricity?

• Plastic, Rubber, Glass

• Wood, Paper, Fabric

• Aluminum, Zinc, Iron

• Metals like copper, silver, and gold

Why are insulators important in electrical circuits?

• Insulators are conductive materials.

• Insulators are unnecessary in electrical circuits.

• Insulators are used to increase the flow of electricity.

• Insulators are important in electrical circuits to prevent the flow of electricity.

What happens when electricity flows through a conductor?

• The conductor shrinks in size

• The conductor turns into a gas

• The conductor becomes magnetic

• The conductor heats up and may produce light or other forms of energy.

How do insulators prevent the flow of electricity?

• Insulators prevent the flow of electricity by attracting electrons from the source.

• Insulators prevent the flow of electricity by generating their own electric current.

• Insulators prevent the flow of electricity by having loosely bound electrons that move freely.

• Insulators prevent the flow of electricity by having tightly bound electrons that do not move easily.

What is the purpose of using insulators in power lines?

• To prevent the flow of electricity to the ground

• To attract lightning strikes

• To reduce the cost of power lines

• To increase the flow of electricity

Explain why metals are good conductors of electricity.

• Metals have a sea of delocalized electrons that can move freely, allowing them to carry electric charge.

• Metals contain insulating properties that enhance conductivity

• Metals have a high resistance to electricity flow

• Metals have a negative charge that attracts electricity

Give an example of a material that can act as both an insulator and a conductor.

• Aluminum

• Graphite

• Rubber

• Copper

How does the thickness of an insulator affect its ability to block electricity?

• Thinner insulators conduct electricity better.

• Thicker insulators provide more resistance to the flow of electricity.

• The thickness of an insulator has no impact on electricity flow.

• Insulators become less effective with increased thickness.
