Provides instructions for preparing, processing, and viewing single-beam reflection holograms in science classrooms. Indicates that the process is simple to demonstrate and moderate in cost. A description of the required equipment (optics table, laser, mirrors, lens, filmholder/plateholder, recording materials, and darkroom chemicals/equipment) is…

Advocates taking students on field trips to highway roadcuts to illustrate various geological principles. Photographs of three roadcuts (with sample objectives and questions/answers for students to answer) are included. Also included are suggestions for preparation, safety, and activities during such field trips. (DH)

Investigated visuo-spatial ability of a control group and an experimental group (receiving 30 minutes of interaction each week) in undergraduate college biology. Results for the subjects (N=84) indicate that visuo-spatial aptitude can be enhanced through teaching. (Descriptions of interaction sessions and explanations of tasks are included.) (DH)

Discusses strategies and activities used to introduce chemistry topics to kindergarten children. These topics include atoms, acids and bases, and molecules and gases. (JN)

Provides instructions and advice on growing the edible mushrooms (Agaricus bisporus) in school. Also suggests several classroom activities using these mushrooms. (JN)

Discusses the behavior, housing, care, diet, and feeding of painted turtles. Also suggests several classroom activities and provides guidelines related to long-term captivity and human disease prevention. (DH)

Describes a terrain model for geologic mapping which, when combined with exercises in rock description, Brunton compass manipulation, orienteering, and geologic report writing, allows students to refine skills needed for summer field camp. Advantages and limitations of the model and its use in a field course are also discussed. (BC)

Discusses types of solar eclipses and the frequency of their occurrence. Emphasis is placed on the May 30, 1984 solar eclipse. Ideas for building a pinhole camera to view the eclipse, to determine if the sun is changing size, and to report scientific findings are provided. (BC)

Discusses the need for including noise pollution in the science curriculum and describes 10 activities for improving students' awareness and understanding of and concern for noise and its effects. (Author/JN)

Describes activities designed to discover what the fluid is in bubble lights used on Christmas trees. Also describes activities using soda straws (to make music and to make smoke). (JN)

Provides: (1) background information on trees, focusing on the parts of trees and how they differ from other plants; (2) eight activities; and (3) ready-to-copy pages dealing with tree identification and tree rings. Activities include objective(s), recommended age level(s), subject area(s), list of materials needed, and procedures. (JN)

Children learn science concepts when they are provided with real-life experiments and problems to solve. Three top elementary school science programs that allow students to hypothesize, discover, and evaluate are discussed. (DF)

Suggests several techniques for using large parabolic detectors (radio and television dishes) to reinforce principles of physics. Includes discussions of: (1) electromagnetic rays, (2) angles of incidence/reflection, and (3) mathematical derivation of focus location. (DH)

Described are the events and results of the Physics Olympics held in February, 1976, at Indiana University of Pennsylvania. Included are highlights of various events. (SL)

Describes three experiments illustrating some technological applications of liquid crystal substances, which are currently used to display numbers and letters by scattering of ambient light. (MLH)
