Describes an activity in which young children explore the concepts of light by predicting the shape of shadows. Different configurations of light sources are used and objects are held in different positions. Sample questions to be asked of the children before, during, and after the activities are included. (TW)

Describes a laboratory experiment in which benzene fluorescence is quenched by bis(acetylacetonato) copper(II). Discusses how this experiment can demonstrate a special technique used in the field of photochemistry. Provides an outline of the experimental procedure and discusses its results. (TW)

Presents step-by-step procedures for two arts and crafts lessons that focus on mammals. Directions are offered for making mammal-shaped dough magnets and also for creating mammal note cards. Examples of each are illustrated. (ML)

Two identical boards and sets of playing pieces can help teach science vocabulary while improving skills in observing, describing, giving clear and complete directions, and listening to and questioning those directions. Children or groups communicate without seeing each other's board. Examples of topics/board design and suggestions for teachers…

Describes outdoor learning experiences in a one-day workshop that introduced teachers, scout leaders, and playground directors to Outdoor Biology Instructional Strategies (OBIS)--a program using games, crafts, simulations, and investigations to sharpen the ecological concepts of children ages 6-16. Includes address for obtaining additional…

The Project for an Energy-Enriched Curriculum (PEEC) analyzed science and social studies textbooks to: document the lack of energy topics; locate niches for energy topics/concepts; and show how PEEC instructional materials could fit into these niches. Findings from this analysis and recommendations supporting the cause of energy education are…

Presents 10 activities in biology, chemistry, physical science, and general science. Activities focus on: alfalfa sprouts; soap test; density; skating on cold ice; Kirlian photography; titration analysis (with program listing); radioactive decay; and others. Each activity includes suggested grade level(s) and procedures. (DH)

Describes science activities related to endangered species designed to sensitize students to the process of extinction; learn of the human role in that process; and emphasize the importance of National Wildlife Week. Provides activities and games such as drift traps, webbing, making corrections, What animal am I?, and Noah's Ark. (JM)

Describes several methods of executing lecture demonstrations involving the recombination of the spectrum. Groups the techniques into two general classes: bringing selected portions of the spectrum together using lenses or mirrors and blurring the colors by rapid movement or foreshortening. (JM)

Describes an advanced, senior-level biochemistry course designed for students planning to pursue careers in nursing, engineering, and agriculture. The course follows a college-type format to expose students to college level course work. Course description, outline, and supplementary materials are included. (JM)

Describes mushroom growing as a school project, a method for illustrating need for carbon dioxide in photosynthesis, construction of a simple phytoplankton sampler, cell division activity using playing cards, blood separation activity, measurement of adaptation and selection pressures, computations in field ecology, and an activity demonstrating…

Describes a fourth-grade unit on density which introduces a concept useful in the study of chemistry and procedures appropriate to the chemistry laboratory. The hands-on activities, which use simple equipment and household substances, are at the level of thinking Piaget describes as concrete operational. (BC)

Gives background information on film selection, lighting, accessory equipment, and techniques appropriate for successful microphotography. Provides a technique for calibrating magnification, light intensity, and shutter speed. (JM)

Lists 25 energy activities and describes two experiments (materials needed and procedures used included) for secondary/middle school students. Like activities for younger children listed in part 1 (appearing in Vol. 65, No. 229), these activities are designed to provide concrete experiences for teaching various aspects of the energy concept. (JM)

Describes simple, electrical projects with dry cell batteries and lamps designed to teach children about conductors, insulators, and switches. Instructions for construction of circuits, the science ideas in each project, and suggestions for extending each of the investigations are included. (JM)
