Uses a diode array spectrometer to explain why blue objects appear red when viewed through the yellowish amber lens of "blue blocking" sunglasses. (JRH)

Describes an in-depth, comprehensive method that enables students to understand the basic concepts of visual perception. (JRH)

Students explore three-dimensional properties by creating red and green wall decorations related to Christmas. Students examine why images seem to vibrate when red and green pieces are small and close together. Instructions to conduct the activity and construct 3-D glasses are given. (MDH)

Describes a lesson in which instruction is initiated through the right cerebral hemisphere by using visualizations as concrete aids to learning. Explanations include a hand model which is used to illustrate the dynamics of guard cell activity of stomates and a paper folding model to show increase in surface area. (RT)

Uses a projector, a prism, and two screens to demonstrate the composition of white light and detect color. (MDH)

Provides background theory and an experiment relating to chemometrics. Describes the phenomenon where solutions are dichromatic or dichromic. Discusses the difficulty students have in describing such solutions that appear to be several different colors at the same time. (TW)

Describes some of the capabilities of the Apple Macintosh computer in constructing stereo pairs for three-dimensional viewing. Discusses various software packages which can produce the desired graphics. Provides examples of how to use these stereo images in geology, chemistry, and psychology. (TW)

Discusses the use of mental ability tests for grouping science students. Describes a study which investigated the analytical skill items on the Otis-Lennon Mental Ability Test for field independent bias. Results indicated that the test is biased in favor of individuals with field independent perceptual orientation. (TW)

The Science in Action series is designed to teach practical science concepts to special-needs students. It is intended to develop students' problem-solving skills by teaching them to observe, record, analyze, conclude, and predict. This document contains a student workbook which deals with basic principles of life science. Six separate units…
