Shadows That Enlighten

by: Dan Vincent and Darlinda Cassel

This inquiry-based investigation focused on shadow measurement and the apparent movement of the Sun throughout the school year. Students would collect data about their shadows weekly. Toward the end of the year, students would then organize and interpret their data. The authors hoped they would discover that the angle of the Sun changes throughout the year, as witnessed by the changing length of their shadows.
