Transparent, Translucent, and Opaque Materials

What happens when LIGHT hits an object?




Three (3) things can happen.
  • Light passes through easily (if the object is transparent)
  • Light is blurred (if the object is translucent)
  • Light is blocked (if the object is opaque)

Materials
  • Transparent object(s) {clear plastic cup, glass, water, etc.}
  • Translucent object(s) {some tinted plastic cups, waxed paper, sunglasses, etc.}
  • Opaque object(s) {some plastic cups, aluminum foil, cardboard, etc.}
  • Flashlight 
  • Plastic plate (optional)

Experiment
  1. Show the children 3 different objects (1 transparent, 1 translucent, 1 opaque).
  2. Have the children predict what will happen when they shine a light on each object
  3. Have the children shine a light on each object, observe what happens, and sketch a picture of what happens and/or record their data in their science notebooks.

     transparent (cup and water)


    translucent (cup)


    opaque (cup)


    For a follow up arts and crafts activity children can use their (recycled ) materials and make a  "Light" mobile to hang. They can look for other lightweight transparent, translucent, and opaque objects to put on their mobile.
