    When an object reflects light
    When an object blocks light
  • Which of these is a man-made light source?
    The Moon
    A star
    A flashlight
    A firefly
  • What happens when light passes through a prism?
    It reflects back
    It speeds up
    It bends and splits into colors
    It disappears
  • Why do we see colors in objects?
    Because they change color
    Because they glow

    The Sun
    A flashlight
  • What is a periscope used for?
    To see around corners
    To reflect sunlight
    To focus shadows
    To measure light
  • Why do shadows change length during the day?
    Because the Earth stops spinning
    Because the Sun’s position in the sky changes
    Because the object moves
    Because light disappears
  • Why does the Moon shine despite not producing its own light?
    It glows from heat
    It makes its own light
    It absorbs light from Earth
    It reflects light from the Sun
  • How can you change the size and shape of a shadow?
    By using mirrors
    By coloring the object
    By moving the object and light source
    By turning off the light
  • Why can’t we see in complete darkness?
    There is no light for our eyes to detect
    Light is absorbed
    Our eyes are closed
    Shadows block vision
  • What is refraction?
    Blocking of light
    Bouncing of light
    Bending of light
    Spreading out of light
  • How does distance from a light source affect brightness?
    Farther makes it brighter
    Closer makes it brighter
    It depends on the time
    It doesn't change
  • How does light travel?
    In a zigzag
    In straight lines
    In waves
    In circles
  • What happens to the size of a shadow when you move an object closer to the light source?
    It becomes smaller
    It disappears
    It changes color
    It becomes larger
  • Why does an object appear black?
    It reflects all colors
    It glows in the dark
    It bends light
    It absorbs all the light and reflects none
  • What is a light source?
    An object that reflects light
    An object that produces its own light
    An object that blocks light
    An object that bends light
  • What happens when light hits a mirror?
