• Switch

• Wire

When does energy transfer occur in the circuit?

• When the switch is open

• When the switch is closed

• When bulbs are removed

• When the circuit is incomplete

In the initial circuit model (Model 1), how many light bulbs were connected?

• One light bulb

• Two light bulbs

• Three light bulbs

• Four light bulbs

Based on the document, what happens to the lights in a school building?

• All lights must be on at the same time

• Lights can only work in adjacent rooms

• Different rooms can have lights on or off independently

• Lights must all be off at the same time

In Model 2 of the circuit, what was observed about the light bulbs?

• All bulbs were equally dim

• All bulbs were equally bright

• One bulb was brighter than the others

• All bulbs were turned off

What is one type of energy conversion that occurs in this circuit?

• Chemical to thermal

• Electrical to light

• Thermal to chemical

• Sound to light

What is a criterion when designing an electrical circuit?

• The cost of materials

• The specific function it needs to perform

• The time to build it

What component allows you to control whether the circuit is complete or incomplete?

• Battery

• Light bulb

• Switch

• Wire

What happens when all three bulbs are connected in the same circuit (Model 1)?

• They use different amounts of energy

• They give off different amounts of light

• They give off the same amount of energy

• They don't work at all
