Make a Sundial

Make a Sundial allows children to investigate the way shadows cast by the sun move and change size during the day to reflect the position and height of the sun in the sky. In the activity, a sundial is created, which can be used to tell the time.

In the first part of Make a Sundial, children place pebbles to indicate position of the shadow every hour during the day; and in the second part, children use the sundial to tell the time. At the easy level, the pebbles are already placed for the children.
