  • When a guitar string is plucked, how does it move to create sound?
    it moves back and forth in small and quick movements
    it only moves upward
    it moves in large circles
    it stops moving completely
  • How does using a larger amount of energy affect an object?
    it creates no change at all
    it only changes the object's color
    it creates a larger change or more motion
    it makes the object stop moving
  • What does energy have the ability to do?
    it makes objects disappear
    it only creates shadows
    it makes things stay still
    it has the ability to create change
  • Which of the following is an example of using energy of motion to change an object?
    warming the sand on the beach
    cooking a hotdog on a fire
    snapping a branch in half
    using an oil lamp to see in the dark
  • How does sound energy travel from a source to our ears?
    in the form of waves
    by heat energy
    through electrical wires
    it does not travel
  • What change is caused by the energy of motion on a scooter?
    it makes the scooter stay still
    it cooks the scooter
    it makes the scooter glow like a light bulb
    it changes the scooter from staying still to moving
  • What is a vibration?
    the repetitive movement of an object back and forth
    a type of electrical energy
    energy that stays in one place
    a form of light
  • Why can we hear the sound an object makes?
    light energy carries the sound
    the object stays far away
    the object stops vibrating
    vibrations give off energy that travels to our ears
  • How is sound produced?
    by plants growing
    from light energy
    by staying still
    from vibrations
  • Which of the following best describes how electrical energy can change an object?
    it allows us to see the words on a page in a dark room
    it makes the water in a lake increase in temperature
    it creates vibrations that tell us a phone is ringing
    it can transform into heat energy that allows us to heat our food
  • Which type of energy can be used to train animals, such as using a whistle?
    sound energy
    heat energy
    electrical energy
    light energy
  • How do plants use light energy?
    to move back and forth quickly
    to produce electrical energy
    to produce sound waves
    to create food so they can grow
  • When grilling meat or cooking a pancake, what change does heat energy cause?
    it changes the object from raw to cooked
    it changes the object from cooked to raw
    it changes the object into light energy
    it makes the object move like a scooter
  • Which of the following explains why sound is heard when a bell's ball strikes the bowl?
    the light energy that is absorbed by the bowl is transformed into a sound
    friction changes its motion leading to a sound
    heat energy from the air is transformed into sound
    after the ball strikes the bowl the bowl vibrates and a sound is heard
