Described is a technique for fiber identification for use by K-6 students. Follow-up activities for elementary and college students are suggested. (CW)

Described are the apparatus and procedures needed for a demonstration of variables which affect centripetal force. Discussed are materials, apparatus construction, calibration, and experimental results. (CW)

Findings from a survey of 20 liberal arts colleges which did not have graduate programs in chemistry are presented. Discussed are regulations, actions taken and costs of academic laboratories regarding the disposal of hazardous waste. (CW)

Proposed is a more didactic version of the electronic periodic table than is being used. The background and use of the numeric system is detailed and illustrated. (CW)

Reviewed are 15 methods for fast slide production. Methods are classified as in-hand methods and farmed-out methods of slide production. Slides are compared to transparencies as another fast presentation aid. (CW)

Three demonstrations (a mechanical model of chemical equilibrium, a demonstration of Raoult's Law, and a demonstration of permanganate reduction) are presented. Materials and procedures are detailed. (CW)

Discussed is wavelet theory, which provides ways to rearrange data to reveal features of a physical or mathematical system which might otherwise be hidden. This theory is compared to fourier analysis and the advantages of wavelet theory are stressed. Applications of this technique are suggested. (CW)

Described are methods which can be used by developing countries to affordably obtain the energy without ruining the environment. The approaches mix efficient end-use technologies with modest increases in generating capacity. (CW)

Procedures for duplicating fossil raindrop impressions are presented. The use of modern and fossil imprints as the basis for qualitative and quantitative lessons in the interpretation of ancient sedimentary features is discussed. (CW)

Discussed are positions on the topic of creationism. The dichotomy between science and religion is analyzed. Middle positions are highlighted and the fundamental issues clarified. Examples that illustrate historical changes in scientific thought are included. (KR)

Described is a study which was developed to find the proportion of cross-dominance in young adults. Procedures and statistical tests are discussed. The tasks used in the assessment of cross-dominance are described. Results indicated that all persons suffered from some cross-dominance. (CW)

Discussed are applications of biochemistry. Included are designed drugs, clever drugs, carcinogenic structures, sugary wine, caged chemicals, biomaterials, marine chemistry, biopolymers, prospecting bacteria, and plant chemistry. (CW)

Discussed is the importance of valence bond theory on the quantum-mechanical theory of chemical structure and the nature of the chemical bond. Described briefly are early VB theory, development of VB theory, modern versions, solid-state applications, models, treatment in textbooks, and flaws in criticisms of valence bond theory. (KR)

The use of actographs for studying animal activity is discussed. Described are running recorders for rodents, perching and feeding recorders for birds, and tilting box recorders for studying the movement of reptiles, amphibians, and arthropods. (CW)

Summarizes the report on undergraduate education in biology published by the National Science Foundation. Discusses the problems and recommended solutions for each of three areas: laboratories and course development; enhancing the quality of teaching; and recruitment and retention of students. (YP)
