Let's Learn About Light is a fun, hands-on science unit that incorporates reading and writing activities, which can be taught over a 1 or 2 week period. In addition to experiments, activity ideas, and printables, the packet includes information pages for you to share with your students to build an understanding of light. Let's Learn About Light focuses on sources of light, shadows, reflection and refraction, and transparent, translucent and opaque objects. Activities to accompany the book Sam and the Firefly, by P.D. Eastman are also included. This packet can stand alone as your light unit or could supplement your existing unit on light. Check out the preview for more information.
