This manual is a teacher's resource and guide book describing activities for elementary students involving the collecting, killing, preserving, and identification of insects. Most activities relate to collecting and identifying, but activities involving terrariums and hatcheries, finding hidden insects, and insect trapping are also described.…

This laboratory manual, containing 44 exercises, is intended to be used as part of an audio-tutorial approach to laboratory work in a life-science course for student nurses. Exercises include basic techniques of miscroscopy, microbiology, electrophysiology, routine biochemical analyses of blood and urine, and microscopic examination of prepared…

The student materials for seventh grade in the Intermediate Science Curriculum Study program are in two volumes: the core chapters and the supplementary excursions. The excursions are departures from the core and are designed for three distinct purposes: (1) to provide more challenging materials for especially interested or talented students, (2)…

Experiments dealing with laser mode structure are presented which are suitable for an upper division undergraduate laboratory. The theory of cavity modes is summarized. The mode structure of the radiation from a helium-neon laser is measured by using a photodiode detector and spectrum analyzer to detect intermode beating. Off-axial modes can be…

Describes the science of hair analysis and its use in the solution of crimes. Methods of analysis and genetic and environmental characteristics which can be inferred are presented. (CP)

The author discusses how plumes of smoke in the air can give us an indication of how atmospheric temperature varies with height. (MN)

A short history of Newton's work in optics, mathematics, and astronomy. (BB)

A teacher of visually handicapped students at the upper elementary level describes a lesson plan from a creative science program which involves students in a model experiment about plant growth. (CL)

Described is a student preparation of YBa2Cu3O8-x, a classroom demonstration of its superconductivity, and an analytical chemistry experiment dealing with the oxidation state of copper in the material. (RH)

Described is a workshop for grades 5-8 school teachers and students related to synthetic polymers. Participants become familiar with polymer theory and practice experiments they can use in class. Sources of materials used in the workshop are listed. (RH)

Gives illustrated directions for five brain-teaser activities/experiments utilizing the sun shining into the classroom: sun shadow lines, analemma, hot-boxes, and solar crafts. (NEC)

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)

Tree frogs are small (2-5 cm) animals which not only interest students but also can be maintained in classrooms for a few days. Characteristics (species, ranges, habitat, reproductive cycle, and locomotion) and housing/care needs are described. Long-term maintenance is not recommended due to the difficulty of providing live food. (DH)

Presents a laboratory exercise designed to introduce graphical extrapolation. Major advantages of the method are in its simplicity and speed. The only measuring devices are a centimeter ruler and a micrometer caliper to check wall thickness. (JN)
