Making A Sundial

Can people really measure time just by using the sun? Scholars venture outside on a nice, sunny day to build sundials and learn how people measured time 600 years ago. The class builds two different sundials while gaining practice with measurement tools. They see how the rotation of Earth causes the sun to move in the sky, creating shadows.
