Experiences and experiments with mirrors will spark pupils' imaginations while providing insights into the nature and behavior of light. (Author/DF)

Several activities related to color are discussed. These include placing different colors on a disk which, while spinning, appears to be white. Also discusses complementary and primary colors. (JN)

Describes construction of a pinhole camera with simple materials and five experiments to be conducted, as well as instructions in creating a working camera obscura. (BR)

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)

Presents experiments with polarized light for grades 8-12 which can produce colorful effects with a minimum of equipment and can illustrate many principles of physics, chemistry, and geology. (MKR)

A short history of Newton's work in optics, mathematics, and astronomy. (BB)

Provides directions for construction of a working model of the eye and specifies some experiments using this model. (PEB)

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)

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)

Discusses the use of shadows to explain such scientific phenomena as umbra and penumbra, eclipses, day and night, seasons, and length of day. Indicates that shadow plays can serve to help the students in understanding more about light. (CC)

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)

Discusses physics, earth science, and physical science concepts that are challenging for students and teachers because they are difficult to understand and demonstrate. Identifies ratio and inverse-square as a unifying-concept approach according to the National Education Standards. Supports teaching based on student-centered activities, long-term…
