What is the purpose of a switch in an electric circuit?

• to change the direction of the electricity

• to allow the electric circuit to be opened or closed

• to provide a "push" for the electricity

• to increase the electric power of the bulb

Metal is __________________ because it allows heat and electricity to flow through.

• magnetic

• a conductor

• an insulator

• a circuit

• Static

• Current

• Circuit

• Battery

The flow of electrons along a path is called _______________________.

On most Christmas lights, when one bulb goes out, the other bulbs on that string of lights will also go out. This is an example of a _________________ circuit.

• simple

• parallel

• series

• closed

Brayson made the circuit shown here in his science class. What is the most likely reason that the bulb is not lit?

• The bulb is cracked.

• He did not use the right size battery.

• He used too many pieces of wire.

• He left the switch open.
