Conductors, Insulators, Circuits Vocabulary Test

During a science fair, Leah tests different wires to see which carries electricity best. She writes down the brightness of a bulb for each wire. What is Leah collecting?

• Energy

• Evidence

• Current

• Circuits

Ben wraps aluminum foil around a wire. The bulb lights up. Then he wraps rubber tape around the same wire and the bulb goes off. Why?

• Rubber is an insulator.

• Aluminum is an insulator.

• Rubber is a conductor.

• Current cannot leave the battery.

Why does hot chocolate cool down when left on a table?

• Particles in the air slow down

• Particles in the chocolate speed up and transfer energy to the air

• Particles in the chocolate stop moving

• Particles vanish
