Provides instructions for producing a spectrum in the secondary science classroom. Offers suggestions for using the spectrum and discusses how to make a rainbow using a garden hose or houseplant sprayer. (JN)

Several simple experiments using easily obtained materials are described which illustrate some of the properties of light (travels in straight lines, reflection, and refraction). (JR)

Discusses the nature of virtual images and how they can be plotted and used to reveal important relationships between objects and their mirror reflections. Describes some applications of virtual images in the theater and classroom. (JR)

Presents activities and experiments that can be performed with mirrors to illustrate the nature and behavior of light. Includes diagrams, directives and investigative questions. (ML)

Describes a number of activities designed to assist student understanding of the phenomenon of light bending when it passes from one meduim to another. (JR)

Describes a series of optical illustions designed to explore the nature and behavior of light, the mechanics and optical principles of eyes, and the brain's learned ability to interpret what we see. (BR)

Describes simple, electrical projects with dry cell batteries and lamps designed to teach children about conductors, insulators, and switches. Instructions for construction of circuits, the science ideas in each project, and suggestions for extending each of the investigations are included. (JM)
