Which answer choice provides the BEST example of a circuit?

• When energy from the wind blows over a beach umbrella.

• When batteries are placed in a flashlight, and it is switched on.

• When the sound from a car stereo shakes the ground.

• When a bologna sandwich fuels you up at lunchtime.

Which answer choice BEST defines current?

• To change from one form to another

• A closed path along which electric current flows

• Required to do work or cause change

• The flow of electricity in a circuit

Electricity can be transformed into all of the following except:

• Gravity

• Light

• Sound

• Motion

Which of the following would be the best material for an electric

current to flow through?

• Glass

• Cotton

• Wood

• Copper

Which description BEST explains how current flows in a circuit?

• When a switch opens a circuit, it allows electric current to flow from

  the battery, to a device, and then back to the battery.

• Electric current flows in a loop from the battery, through wires and

  devices, and back to the battery.

• Energy flows from a switch into the battery where the energy is

  transformed and sent to devices like light bulbs for use.

• Electric current flows from the battery, through wires, into devices

  that can transform electrical energy.

Observe the circuit in the photo. When the switch is closed, will the lightbulb light?

• Yes, because the switch, the battery, and the lightbulb are all

  connected in a circuit.

• No, because the lightbulb in not connect to both sides of the switch.

• Yes, because the switch is connected to the lightbulb and controls

  the flow of energy.

• No, because the wires are not connected to both sides of the

  battery.
