A student builds a circuit made up of a battery, two light bulbs, and a switch. What will the student most likely observe in this circuit?

• Light bulb 1 and light bulb 2 will both be on

• Light bulb 1 will be off, but light bulb 2 will be on

• Light bulb 1 and light bulb 2 will both be off

• Light bulb 1 will be on, but light bulb 2 will be off

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

What is missing from this circuit? Why would the light bulbs be off?

• The battery, there is no power for the circuit to work.

• The switch is open, so the circuit is broken.

• The third light bulb, that is needed to complete the circuit.

• The wires are not connected properly.

What is an electrical circuit?

• lets you turn the energy on and off

• a closed path where where electricity flows

• stop electricity from flowing through

Is the following photo of an open circuit or closed circuit? 

• closed circuit which allows electricity to flow

• open circuit which does not allow electricity to flow

Will the light bulb in this circuit light and why/why not?

• yes, because it has two batteries

• no, because the switch is open

• yes, because it is in a circuit

• no, because the bulb is burned out
