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 no effect on the other lightbulbs.

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

• A

• B

• C

• D

A student builds a circuit made up of a battery, two lightbulbs, and a switch, as shown below.

What will the student most likely observe in this circuit?

• Lightbulb 1 and Lightbulb 2 will both be on.

• Lightbulb 1 will be off, but Lightbulb 2 will be on.

• Lightbulb 1 and Lightbulb 2 will both be off.

• Lightbulb 1 will be on, but Lightbulb 2 will be off.

Most cars have lights, power locks, radios, and other equipment that use electricity. Electric circuits power this equipment. Each circuit has a fuse that completes it. The picture below shows one type of fuse a car may have.

Which of these describes one thing that could happen if the wire in a car fuse burns out?

• The car's lights will burn brighter

• The car's radio will not work

• The car's turn signal will blink too slowly.

• The car's power windows will open faster

Which object requires only mechanical energy to perform its main function? (5.6A)

• 
• 
• 
• 

A group of students built the circuit shown below.

The lightbulb does not glow. Which statement explains this observation?

• The battery is not charged

• The lightbulb is not part of a complete circuit

• The circuit does not have a switch

• The bell uses most of the energy from the battery

Look at the image and answer the question.

• Heat

• Mass

• Light

• Water vaper

An old-fashioned metal toy is shown below. When the candle is lit, the carousel of horses begins to turn. Which of these correctly describes the energy that makes the carousel turn? (5.6A)

• Heat from the candle produces currents of warm air.

• Heat from the candle produces electrical energy.

• Light from the candle produces mechanical energy.

• Light from the candle produces wind currents.
