Features science concepts with accompanying activities teachers can use in the classroom. Presents a lesson in optics that utilizes optical illusions to illustrate scientific points and allows students to use the following processes: observing, communicating, controlling variables, hypothesizing, and gathering and interpreting data. (ET)

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)

Presents two views about lenses and optics in attempt to clarify a story written by Carolyn Hermann, "Through the Magnifying Glass." Cites two references for additional reading on students' optics difficulties. (RT)

Simple laboratory investigations are given which expose elementary students to optical crystallography techniques. Procedures and materials are designed for sixth-grade students. (SA)

Activities used to teach optics to fifth and sixth graders are presented. Moon phases and solar and lunar eclipses are included. (SA)

Provided are hands-on activities on light, simulated emission, light radiation, and common uses of lasers. Directions and materials are discussed. Included is a diagram of a laser model. (CW)
