Bringing Light onto Shadows

by: Lloyd H. Barrow

“What starts out long but gets shorter then longer each day?” Shadows! This students clever riddles was an opportunity to investigate how the Sun’s daily position in the sky influences shadow length. Thus began a mini-lesson which was created to help third-grade students understand that a shadow occurs when an opaque object blocks light (Shapiro 1994). The study of light and shadows teaches students about properties of light and materials.
