In an activity, students make a large human sundial In an activity, students make a large human sundial. The sundial uses the sun to tell the approximate time of day. How is this possible? The sun moves across the sky each day because it spins around Earth. The sundial measures the distance from Earth to the sun as it moves across the sky. Earth moves around the sun each day, making the sun appear to move across the sky. The position of the sun in the sky appears to change during the day because Earth rotates on its axis.
