  • 6. Shadow Activity
    You will need 3 people to do this activity. The first person will need to hold the flashlight, the second person will be the drawer and the third person will be drawn.
    You need to place a piece of black construction paper on the board (being held by tape). Have someone stand in front of the black construction paper facing sideways and have the other person stand in front of them holding the flashlight . Have the third person trace the person standing there.
    Take turns until everyone has completed the activity.
  • 7. Shadow Activity Cont.
    The flashlight will cast a shadow of the person standing there on the black construction paper.
    The flashlight acts like the sun wave and the object that blocks the flashlight (sun wave) is the person being drawn thus casting the shadow of the person (object) on the black construction paper.
  • 8. Where is my Shadow?

    In the first picture the shadow is bigger because shadows are longer in the morning and evening.
    In the second picture the shadow is smaller because shadows are shorter at noon. However they are much darker at noon then in the morning or the evening.
