After several attempts to turn on a light using a simple circuit, a student concludes that the circuit must be closed in order for the light to turn on. Is the student’s conclusion reasonable?

• A No, because circuits cannot turn on lights

• B No, because the circuit needs to remain open in order for it to work

• C Yes, because all conclusions are correct

• D Yes, because circuits must be closed in order for the electricity to flow through them

In science class, students investigate ways to build circuits. Which items should students choose to create a working electrical circuit?

• One copper wire, wood chips, and a lightbulb

• Two copper wires, a plastic straw, and a lightbulb

• Two copper wires, a battery, and a lightbulb

• Wood chips, iron filings, and a battery
