A student constructs the circuit shown for a science demonstration. With the switches in these positions, which lights are on?

• All the lights

• 1 and 2 only

• 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 parts 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?

• 1, 3, 4

• 1, 2, 3, 4

• 3 and 4

• 1, 3, 4, 5

The circuit below does not work. Which procedure would most likely allow the bulbs to light?

• Open the switch and then connect the two wires that are attached 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.

In some circuits that are used for decorating, one burned-out lightbulb will prevent the other lightbulbs from lighting. In other circuits, one burned-out lightbulb will have no effect on the other lightbulbs. In which of these circuits will the other light bulbs still light even if one bulb is burned out?
