Describes a technique to improve the adaptation, development, and utilization of laboratory worksheets. Two sample worksheets (on decomposition of ethanol and on solubility of potassium chloride) are included. (JN)

Contains a reading list of articles published in 1985 covering 14 biological topics. Includes descriptions, procedures, and references for 26 experiments. These investigations deal with selected concepts in biology, ecology, chemistry, and physics and include computer-based instruction. (ML)

Provides an updated list of films and videotapes that was initially developed in 1970 for the British Society for Developmental Biology. Includes sections on cellular and genetic aspects, invertebrates, and vertebrates. The newer films are listed by title, in alphabetical order, with details of the maker, content, and duration. (ML)

Determined which form of kinetic structure (high or low) and/or micrograph content (unified or varied) was most effective on introductory college biology students' (N=100) achievement of reading micrograph skills. Findings, among others, suggest that high kinetic structure instruction does not affect actual reading micrograph skills, but…

Provides sources of nonanimal biochemical materials (which are relatively inexpensive, readily available, and require no special storage) suitable for use in biochemistry experiments. They are presented under these headings: (1) enzymes and other proteins; (2) carbohydrates; (3) lipids; (4) nucleic acids; and (5) metabolism. (JN)

This article contains suggestions for introducing the scientific concept of matter and demonstration acids and bases using low-cost, collectible supplies. Sample questions and experiments are listed to help students explore these ideas. A list of household supplies to be used in the experiments is given. (DF)

Using a developed structural schema specifying the categories of knowledge important to understanding a scientific theory, two experiments involving 82 undergraduates were conducted to assess the effects of structural schema training and text organization on the comprehension and recall of scientific prose. (Author/PN)

A possible solution for classroom plant growth where space and time are minimal. Care and plant propagation are discussed. Several experiments in which bryophyllum can be successfully used are described. (EB)

Discusses teaching the concept of temperature at several levels of difficulty; includes ideal gas thermometers and the kinetic theory of gases. (MLH)

Presents syllabuses for various British curriculum projects in physics and chemistry that include thermodynamics concepts. (MLH)

Discusses the measurement of electrons ejected from a system which is being irradiated with X-rays or ultraviolet photons, and a theoretical model for calculating core-electron ionization energies. (MLH)

Discusses the energies, structures, and efficiencies of interconversion of the various electronic states within transition metal complexes. (MLH)

Listed, with comments and descriptions, are the addresses of suppliers of crystal and molecular models. Included are United States and English suppliers. (SL)

Describes some recent advances in enzyme structure and action, including a description of enzyme-substrate interaction. Discusses the methods for determination of amino acid sequences in proteins; the actions of chymotrypsin, trypsin, and elastase; and details of the enzyme-substrate complex derived from kinetic studies and x-ray diffraction…

Examines recent studies of the elimination-addition mechanism of acyl group transfer, in which an acid function moves from one acceptor to another. Presents diagnostic evidence for this mechanism and discusses acyl group transfers in metabolism. (MLH)
