Science Experiments: Twinkle Twinkle Stars and {Learn & Play Link Up}

Wednesday, November 4, 2015

I love simple and easy to prepare experiments.  That’s why when we received a Janice VanCleave’s book as present last year, I was so elated! I love her books of experiments!  So we are trying some of it and so far the boys are enjoying it!TwinkleStars
Objective:  To simulate the twinkling of stars in sky.

Materials needed:
  • a large square foil
  • glass bowl (preferably 2 liters)
  • tap water
  • a torch/flashlight
  • pencil
  • DSC_1001
    Procedure:
    1.  Crumple your square foil and place it on a table or on a floor.
    2.  Fill your clear bowl with tap water and place it on top of the crumpled foil.

    3.  Darken the room by turning off the lights.  Hold the torch or flashlight above the bowl.  Distance from the bowl  is about 12 inches.
    4.  Observe the foil through the undisturbed water.

    5.  Now using your pencil, tap the surface of the water gently.  Observe the foil through the moving water.

    What happened? 
    The light rays reflecting from the foil when there was a movement in water appears to blur or twinkle. 

    Why? 
    The movement of the water causes the depth of the water to vary.  The light rays twinkle because they bend or refract in different direction when it passed through the different depths of water. 

    This is similar to the light rays of the stars.  They appear to be twinkling when you are observing from earth because they refract differently as the light rays move through the different thickness of air in the atmosphere.  Scientifically, this twinkling phenomenon is called ‘scintillation’.
