Object:
a ping-pong ball with half painted one color and the
other side left white
(Hold the ball so that one side of the children sees the
colored side and the other sees the white side. The children
might have to be split in half so that one side is opposite the
other.) Good morning. What is the color of this ball? (The
children on one side will say "black" [or whatever color you have
painted it and the other, of course, will say "white"].)
Why do some of you tell me it is one color and the other side
tells me it's "white"? How can that be? Can you both be right? Of
course you can. How? You might both be right if I have painted
