Grade 5 Physics Quiz: Static Electricity and Conductors/Insulators

What is a conductor?

• A type of train ticket

• A material that allows the flow of electric current.

• A type of musical director

• A type of heat insulator

Give an example of a good conductor of electricity.

• Wood

• Plastic

• Rubber

• Copper

Why are metals good conductors of electricity?

• Metals have a high resistance to the flow of electrons

• Metals have free electrons that can move easily

• Metals have a low density which allows electrons to move freely

• Metals have a positive charge that attracts electrons

What is an insulator?

• A material that allows the flow of electricity

• Something used to keep drinks cold

• A material that does not allow the flow of electricity.

• A type of musical instrument

Give an example of a good insulator of electricity.

• Metal

• Rubber

• Glass

• Water

Why are rubber and plastic good insulators of electricity?

• Easily conducts electric current

• Low resistance to the flow of electric current

• Attracts electric current

• High resistance to the flow of electric current

What is static electricity?

• The flow of electric charge through a conductor

• The energy stored in a battery

• The movement of electrons in a closed circuit

• The build-up of electric charge on the surface of objects.

How is static electricity different from current electricity?

• Static electricity is the flow of electric charge through a conductor, while current electricity is the build-up of electric charge on the surface of an object.

• Static electricity is the build-up of electric charge on the surface of an object, while current electricity is the flow of electric charge through a conductor.

• Static electricity and current electricity are the same thing.

• Static electricity is only found in batteries, while current electricity is found in lightning.

What causes static electricity to build up on objects?

• Transfer of electrons between objects

• Heat transfer between objects

• Magnetic attraction between objects

• Friction between objects
