What Causes Shadows?

What happens when light is blocked by an OPAQUE object?


Materials
  • flashlight or other light source
  • opaque object

Directions
  • Have students PREDICT what will happen when light is blocked by an opaque object.
  • Shine a flashlight or other light source on the wall.
  • Choose an opaque object to put in front of the light source to block the path of light.
  • OBSERVE.  (A shadow should form.)
  •  Have the students RECORD their observation(s) in their science notebooks.
 
    Other Activities
      • This same activity can be done outside using the Sun instead of a flashlight!


      • Children may enjoy making animal shadows on the wall/ground.
      • A nature walk on a sunny day is also fun to observe shadows in nature. (Trees make great shadows!)
