Which item is NOT a good conductor of electricity?

• a tin can

• a rubber tire

• a copper coin

• an aluminum wire

Why is copper used in house wiring?

• It's magnetic.

• It's an insulator.

• It's an electrical conductor.

• It's hard to bend into new shapes.

Which term should be used to describe materials that easily transfer

electricity?

• conductors

• insulators

• magnets

• resistors

Which object is attracted to a magnet, conducts electricity, and conducts heat?

• aluminum foil

• cotton ball

• iron nail

• wooden toothpick

Kevin is conducting an experiment to explore how different types of materials

(paper, wood, and glass) can affect the strength of a magnetic field. He does

this by placing a sheet of each material between a magnet and the magnetic

object and observing the results.

Which step would be MOST important to include in the experiment to show how

the type of material affects the magnetic field?

• using the same color of paper, wood, and glass

• using the same weight of paper, wood, and glass

• using the same thickness of paper, wood, and glass

• using the same temperature of paper, wood, and glass
