Presents an illusional arena by offering experience in optical illusions in which students must apply critical analysis to their innate information gathering systems. Introduces different types of depth illusions for students to experience. (ASK)

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

Provides classroom activities centered around how the electromagnetic spectrum yields vital insights about the evolution of the universe. Activities targeted for grade levels 6-12 illustrate the importance of light and color in space exploration. Includes a poster. (Author/SOE)

Explains how digital technology can be used as a tool for teaching students the skills of observation, questioning, information gathering, classifying, predicting, and hypothesis testing. (Author/SOE)

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

Presents scientific explanations of primary colors and color mixing, black and white surfaces, the spectrum and the ability of the eye to distinguish color difference, the description of color, and the appearance and optical properties of metals. Contains 16 references. (Author)

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)

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…
