The Australian Science Education Project is producing a series of units designed for use in grades 7 - 10. This first trial edition contains a teachers guide, providing an overview of the unit and advice on mice management and classroom organization; booklets for students ("Mammals,""Investigations,""Care and Handling of…

Lists some reasons why the vast resource potential of entomology remains largely untapped by teachers of general biology. (LS)

First of a series showing ways in which the preschool setting can provide exploratory activities for the young child seeking to become acquainted with the world about him. Suggests ways to present the concepts of climate, clean air, personal space, and noise level. (EB)

Recapitulates the theory behind contact potentials from the 18th century to present day. (CP)

This article tells how to prepare and use frog leg bones in the classroom. (BB)

An explicit physical interpretation of the electromagnetic vector potential is indicated as field momentum available for exchange with kinetic momenta of charged matter. (BB)

Reports the development of "interrupted guidance" and slide tape instructional units for college biology and microbiology laboratory courses to counter problems of decreasing student ability and preparation, decreasing funding, increasing costs, increasing enrollment, and decreasing student-faculty interchange. (SL)

Describes a method of teaching reading to third grade students which incorporated extensive handling of science material. (SL)

Describes the role of eight different metal ions in the chemical functioning of the human body. (SL)

Media is used as a supplement in a science education program based on the inquiry method. Students work in small groups and rotate from station to station. (STS)

Describes a rotating chair with sliding calibrated masses suitable for demonstrating and determining the conservation of angular momentums. (SL)

Presents results of a trend survey of the present and planned use of electrical and electronic instruments. Microprocessors were found to have the highest predicted growth rate of all instruments included in the survey. (SL)

Includes procedures for demonstrating anaerobic respiration in peas, isolating virgin Drosophila females, solving mortality problems in young gerbils, measuring dissolved oxygen, constructing models for transpiration and DNA molecules, freezing chick embryos, mixing nutrient media, illustrating Darwinian ecological principles, and detecting…

Describes the construction of an inexpensive apparatus for separating proteins by polyacrylamide gel electrolysis in the presence of sodium dodecyl sulphate. (TW)

Discusses the use of the FT-IR spectrometer in analyses that were previously avoided. Examines some of the applications of this spectroscopy with aqueous solutions, circular internal reflection, samples with low transmission, diffuse reflectance, infrared emission, and the infrared microscope. (TW)
