“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.

Students in a third grade class learned how shadows change by mapping the changes in a flagpole shadow at various times in the day. From those observations they formulated a hypothesis about their own shadow and collected data to see if they were correct. Using a golf tee and flashlight students explored the shadows formed in a darkened room. These simple inquiry based activities helped students understand the relationship between a light source and shadow formation.
