The slime mold Physarum polycephalum provides an easily maintained classroom plant which can act like an animal. Directions are given for: acquiring the organism; activating it; observing its life cycle; and viewing protoplasmic streaming. (DH)

Presents a science activity that illustrates the need to collaborate in scientific inquiry. The example utilized describes the methods used by the Roman doctor Galen to treat epilepsy. (MDH)

Provides guidelines for simple acceleration experiments with string and attached weights as a means to stimulate the reticular activating system (RAS) of the human brain. Several methods (discrepant events, curiosity, choices, and doubt) are suggested for promoting RAS high-level thought. String drop experiments provide concrete experiences with…

Presents comments on problems voiced by teachers about conducting science fairs with middle school children, also cites some advantages of science fairs. A list of simple experiments is offered that are considered within the interests and intellectual range of middle school children. (Author/EB)

Sixth graders participated in a long-term project involving archaeological processes. Activities included finding background information, site preparation, excavation, record keeping, cleaning artifacts, and classifying items. This pilot project was very successful in Arizona and will be expanded to include more grade levels and groups. (DH)

Procedures for dying and mordanting wool fibers and for preparing dyes from red onion skin, purple cabbage, pine needles, and purple lilac are presented. Information on the history of dyes and on how dyes work is included. (JN)

Sixth graders built working "robots" (or grasping bars) for remote control use during a unit on simple mechanics. Steps for making a robot are presented, including: cutting the wood, drilling and nailing, assembling the jaws, and making them work. The "jaws," used to pick up objects, illustrate principles of levers. (DH)

Nonsense botany, an easy, amusing way of learning the principle of nomenclature, involves using English words (in Latin constructions) to describe a make-believe plant; a drawing of the plant accompanies the pseudoscientific name. Suggests that students use this technique (developed by the nineteenth century British humorist Edward Lear) when…

Examines science achievement and attitude scores of fifth-grade students obtained from the Second International Science Study. Compares these results to those obtained from students in 1970. Data related to biology, space sciences, sex differences, and other areas are highlighted. (JN)

Offers suggestions for activities that demonstrate the principles of osmosis. Explains how decalcified chicken eggs can be used to give students practice with measurement, experimental procedures, and science principles. (ML)

Suggests using squids for classroom investigations. Background information about these marine animals and a dissection activity are included. (JN)

Discusses the culturing of microorganisms as a laboratory activity emphaszing the growth of microorganisms in food. Provides background and safety information, procedures, and additional ideas. The complete unit (teacher's guide, student worksheets, evaluation and assessment, and resources for students and teachers) is available from the author.…

Provides background information on honey ants. These ants are found in dry or desert regions of North America, Africa, and Australia. Also provides a list of activities using local species of ants. (JN)

Teachers may introduce students to anamorphic art (images designed to be looked at with conical mirrors or with mirrors diagonal to the image) with inexpensive cylindrical mirrors. By using polar graph paper, images can be made "correctly distorted" and will appear normal when viewed with a cylindrical mirror. (DH)
