Discusses how to stop a spinning object (such as rotating fan blades) by humming and the perception of curious blue arcs around a light. Background information, relevant research, and activities related to these two topics are provided. (JN)

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

The effect of background color on the perception of color by students is discussed. Explanations on why students only see certain colors when viewing colored marks on a blackboard through different color filters are provided. (KR)

Stereoscopic photo activities for students are described for the purpose of motivating students in earth science. Included also is the necessary equipment for obtaining the three-dimensional effect. (SA)

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

Provides instructions for constructing an Ames window tunnel, a device that illustrates illusion and perception. (CS)

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)

Described are alternative approaches for developing visual perception skills found in using selected science experiences. Use of various science programs available, such as ESS, SCIS, OBIS and Matal, is suggested. Visual sequencing is prescribed and described. (EB)

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

Described is an color-making activity where students use food coloring, eyedroppers, and water to make various colored solutions. Included are the needed materials and procedures. Students are asked to write up the formulas for making their favorite color. (KR)

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…
