This activity is about discovering that our eyes need light to see and in order for something to be seen, we need light. The activity works best on a cloudy day when not much sunlight is lighting the room, but make your room as dimly lit as possible. Place some dark-colored objects in the center of a circle and ask students to describe the objects. They will be able to see the objects, but not well. A materials list, internet resources, standards, and safety practices are provided. This book selection also includes the Table of Contents, Preface, About the Editors, Introduction, Simple Graphing for Young Children, Science Teaching Boards and Boxes, Basic Materials List, and Index.
