Um, is this for real?    

If you're really asking why one side of the sphere isn't illuminated,
I believe the standard elementary school experiment involves a ball
and a light bulb.  If you're asking why the same side of the moon
is always dark, it's because the gravitational pull of the earth
has "locked" the moon so that the same face is always towards earth.
