Saturday Morning Science: Sand & Water Clocks

10 am to noon
Taught by Mark Kent

Sand and Water Clocks

Water clocks were first developed by the ancient Egyptians some 3000 years ago, and were used to tell time on cloudy days or at night. While sun clocks were good for measuring large amounts of time, water clocks and sand clocks gave a means of measuring shorter amounts of time. For example, in the heyday of Athens as a direct democracy in the 4th century BC, citizens were permitted to address the gathering for the amount of time that a small water clock would run.

Sand clocks were developed around the same time as the first water clocks. Sand clocks are
often called hourglasses, but the distinctive shape is not limited to something that will time an hour: small sand clocks are sold for use in cooking, in games, in other applications, and most of the applications use a good deal less than an hour.
