Which of these changes to the electric circuit shown will cause the lightbulb to light up? (5.6B)

Turning one battery so that its positive end connects to the other battery's negative end

Straightening the wire so that the current can flow more easily

Adding a switch and more wire so that the current can flow more easily

Making the length of wire the same on both sides of the lightbulb

The diagram shows the metal posts that are usually found on a battery. The battery can be connected to a bell and a switch to produce sound. Which statement best explains why there are two metal posts on the battery? (5.6B)

The battery needs to form a complete circuit that starts with one metal post and ends with the other metal post.

The battery needs only one metal post to connect to the bell, but the other metal post is present in case the first post fails to work.

One metal post makes a complete circuit with the switch, and the other metal post makes a complete circuit with the bell.

One metal post makes the bell start to ring, and the other metal post makes the bell ring louder.

A group of students built the circuit shown here. The lightbulb does not glow. Which statement explains this observation? (5.6B)

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.

Students constructed a circuit using different-colored lightbulbs. What will happen if Switch 3 is closed and the other switches are left open? (5.6B)

Only the white and yellow bulbs will operate.

Only the white bulb will operate.

None of the bulbs will operate.

Only the red and blue bulbs will operate.

The circuit shown does not work. Which procedure would most likely allow the bulbs to light? (5.6B)

Connect the two wires that are attached to the wood block

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 the open the switch

Move the switch closer in the circuit to the battery

Why is electrical wiring usually made from copper?

Because copper conducts electricity

Because copper insulates electricity

If no changes are made to this circuit, what will the results be?

Only the left bulb is lit because it has a closed path. The right bulb is not lit because of the open switch

Both bulbs are off because the switch is open

Both bulbs are lit because they each have a complete, closed path to the battery

Only the right bulb is lit because an open switch causes the energy to flow to the bulb.

A material that allows electricity to flow through it. The circuit is complete.

A material that does not allow electricity to flow through. It stops the flow of electricity.

Students conducted an investigation using the equipment shown in the picture. The results from their investigation are shown in the table. Study the results in the table carefully. What investigation were the students most likely testing?

D. Insulation of Electrical Energy

A. Conduction of Thermal Energy

B. Conduction of Electrical Energy

C. Insulation of Thermal Energy
