A student constructs the circuit shown for a science demonstration

With the switches in these positions, which lights are on?

• All the lights

• Lights 1 and 2 only

• Lights 3 and 4 only

• none of the lights

A student builds a circuit allowing the lightbulbs to light, the buzzers to make sound, and the motors to turn.

Which two switches can be open and still allow all of the ports to work?

• switches 1 and 3

• switches 1 and 4

• switches 2 and 3

• switches 3 and 4

This circuit has five light-emitting diode, or LED, lights. It also has one battery and one switch.

Which LEDs produce light when the switch is in the position shown?

• LEDs 1, 3 and 4 only

• LEDs 1, 2, 3, and 4

• LEDs 3 and 4 only

• LEDs 1, 3, 4, and 5

The circuit shown does not work

Which procedure would most likely allow the bulbs to light?

• Open the switch and then connect the two wires that are attahed to the wood block

• Switch the positions of the two wires that are connected to the battery and then open the switch

• Move the switch closer in the circuit to the battery

• Connect the two wires that are attached to the wood block

The diagram shows an electric circuit with four bells that a student plans to build

When the student connects the wires as shown, which of the bells will ring?

• Bell 1 only

• Bells 1 and 4 only

• Bells 3 and 4 only

• Bells 1, 2, 3, and 4

In some circuits that are used for decorating, one burned-out lightbulb will prevent all the other lightbulbs from lighting. In other circuits, one burned-out lightbulb will have other effects on the other lightbulbs.

In which of these circuits will the other lightbulbs still light even if one bulb is burned out?

• 
• 
• 
• 

All the lightbulbs in this circuit are lit.

Which change would cause all the bulbs to go out?

• removing wire 1

• removing wires 2 and 4

• removing wires 2 and 5

• removing wires 3 and 4

This circuit has three lightbulbs and a bell

Which procedure will result in only the blue lightbulbs operating?

• Close switches 1 and 2 and leave switch 3 open

• Close switch 3 and leave switches 1 and 2 open

• Close switches 2 and 3 and leave switch 1 open

• Close switch 2 and leave switches 1 and 3 open
