The Clock of Eras

$120.00

The Clock of Eras represents the entire history of our Earth.

It’s a twelve-hour clock. But this clock is like no other clock, for the “hours” on our clock are very long. In fact, each hour represents three hundred seventy-five million years. Written as a numeral, that is 375,000,000 years! The whole twelve “hour” clock represents four billion, five hundred million years of Earth history! That is 4,500,000,000 years.

Includes: Clock of Eras impressionistic chart, cut-out pieces, and three levels of arrows with descriptions.

Instructions: Cut out each piece of the clock and arrow before laminating.

Size: 18″ x 24″
