Sandy built a circuit that would light a light bulb. When she connected the wire to the battery, however, the light bulb did not light. What is the most likely reason the light bulb would not light?

• The circuit was not continuous

• The wire was made of copper

• The switch was closed

• The battery was not powerful enough

What energy transformation takes place inside a toaster?

• electrical to light energy

• electrical to sound energy

• electrical to light and thermal energy

• electrical to sound energy

Jessica sets up a simple circuit. She observes that the light bulb does not light. Which action will most likely cause the light bulb to light?

• closing the switch

• using a different battery

• removing one of the wires

• changing the positions of the wires
