How To Make A Sundial
Before clocks and watches, if you wanted to know what time it was, you checked the local sundial. From ancient times, people used sunlight and pillars to cast shadows on the ground. These shadows were measured and adjusted for the time of year. Those measurements were used to tell the time of day.
A great summer project for you and your kids is making a sundial of your own. You can make a sundial with a few household items and work together to get an accurate measurement of time.
