This is a four-day lesson plan with related activities for grades K-2 on the topic of shadows.  It is designed to demonstrate the relationship between light, heat, and shadows and to help young children build a conceptual base for future understanding of heat transfer and light energy.  The lesson revolves around Bear Shadow by Frank Asch, a story about a bear that tries to escape a shadow that seems to be chasing him. Students will create scale model shadows of Bear's neighborhood, then apply their understanding to design shadows of 3D objects (including a globe). Included are printable student activity sheets and science content support for teachers.  This is part of a larger collection of lessons, all of which are aligned with specific AAAS Benchmarks for Scientific Literacy.
