Sundials - World's Oldest Clocks

North American Sundial Society

nass_news_2011_nov_ConnetquotSecond-grade students at Connetquot Elementary School in Islip, New York, created sundials using paper plates and pencils.   The pencil gnomons were set mostly vertical by the students and then they traced the resulting shadows at three times during the day.  This helped teachers Leslie Davis and Melissa Love demonstrate the sun’s apparent movement in the sky and talk about the earth's rotation as the cause. "The students really had fun," said Love, "and they were able to recognize that a sundial is a tool that can be used to measure time."
