Go outside om a sunny day and look at\on your shadow! early in\at the morning and late in the afternoon, it is long. at lunchtime, it has\is very short. this is because the earthmoves around the sun and the sun is in a different place in\on the sky and different times of the day. sundials use shadows to tell the time. they have\are the oldest way to tell the time!
