Light Test Tomorrow

Your child came home with a review sheet yesterday for our test on Friday. If your child misplaced it, I have added the information below:

  • When light is reflected the light hits the object and it bounces off.
  • To make a shadow you need: a light source, an object, and a blocked path.
  • The shadow is shortest at noon.
  • Light travels in straight lines and some waves.
  • When light travels from air to water it slows down and looks like it bends (think about pencil experiment).
  • When a light source is blocked a shadow forms.
  • Man-made light: light bulb, lantern, lamp, flashlight
  • Natural light: sun, stars, firefly
  • Opaque: No light passes through (examples: rock, people, wood)
  • Translucent: Some light passes through (examples: tissue paper, waxed paper)
  • Transparent: Light passes through (examples: glass, overhead, glasses)
  • When light passes through a prism, it separates into colors.
  • Think about the best color shirt to wear on a hot day and why.
