If you replace the paper clip with a plastic spoon, what is the plastic spoon acting as?

• A conductor
• A diode
• An insulator
• A switch

Would would best complete this circuit?

• A wire
• A switch
• A battery
• A light bulb

Which one will still function if one light bulb goes out?

• Circuit A

• Circuit B

This circuit has a battery, buzzer, and switch.
When the switch is closed the buzzer will sound because -

• the switch gives energy to the battery
• the buzzer is made of special plastic
• the wires are cooled by the surrounding air
• electricity can flow in a complete path
