3. Day and Night At first people used the sun and the moon to tell time - day and night.

4. Sundials Sundials were used to tell time by early man. Sundials use the shadow made by a stick to show the time.

5. Hourglass The hourglass was also used by early man. The hourglass is just like one of our egg timers or game timers. Sand falls from a top glass ball to a bottom glass ball in a certain amount of time such as a minute or an hour. (Insert picture of Hourglass)
