Name ______________________   Date ____________

  1. What carries energy from a ringing bell to your ear?

    • Light
    • Sound
    • Electric current

  2. Which of these is an example of heat energy traveling from one place to another?

    • A radiator warming the air in a room
    • A book sitting on a shelf
    • A rock lying still on the ground

  3. Energy always moves from a source to some other place. It does not just stay put.

    Circle one:   True   False

  4. Which pair correctly matches an energy source with where its energy arrives?

    • Lamp to your eyes, by light
    • Battery to the wall, by light
    • Bell to a rock, by heat

  5. In a simple circuit, what carries energy from the battery to the bulb?

    • The plastic casing of the battery
    • The bulb glows on its own, with no help
    • The wires, through electric current

  6. Which best describes how light travels from a lamp to your eyes?

    • It needs a wire to reach your eyes
    • It travels through the air until it reaches your eyes
    • It stays inside the lamp and never leaves

  7. Which situation is NOT an example of energy traveling from a source to a destination?

    • A rock sitting still on a shelf
    • Light moving from a lamp to a page you are reading
    • Heat moving from a stove to a pot of water

  8. Mia unplugs the wire between the battery and the bulb. What happens, and why?

    • The bulb stays lit, because bulbs make their own energy
    • The bulb turns off, because the battery loses its energy instantly
    • The bulb turns off, because electric current can no longer carry energy to it

How energy travels around W1-mt_X_aDUBh-HF-s1

  1. Sound · The bell makes the air vibrate, and those vibrations carry sound energy to your ear.
  2. A radiator warming the air in a room · The radiator is hot, so heat energy moves from it into the cooler air around it.
  3. True · Sound, light, heat, and electric current all carry energy away from where it started.
  4. Lamp to your eyes, by light · A lamp is the source, and the light energy it makes travels to your eyes.
  5. The wires, through electric current · Electric current flows through the wires, carrying energy from the battery to the bulb.
  6. It travels through the air until it reaches your eyes · Light energy leaves the lamp and travels through the air until it reaches your eyes.
  7. A rock sitting still on a shelf · A rock sitting still is not transferring energy anywhere, so it does not fit the pattern of energy travel.
  8. The bulb turns off, because electric current can no longer carry energy to it · Without the wire, electric current has no path, so energy cannot travel from the battery to the bulb.
