"Eyes on the Sky, Feet on the Ground" - Smithsonian Institution
Chapter One of this electronic book pertains to the phenomenon of shadows (how they are made), then uses measurements of shadows to track the motion of the sun across the sky. A companion activity done in the classroom uses an earth-sun model to reproduce the same pattern of shadows the students observed during the day. An outdoor model uses a small clear dome for the sky on which the students record the sun's path. Building and using a sundial is the last activity illustrating the sun's motion.
