Gives the background history of the simultaneous discovery of acid-base relationships by Johannes Bronsted and Thomas Lowry. Provides a brief biographical sketch of each. Discusses their concept of acids and bases in some detail. (CW)

This is the appendix to Ranger Rick's "Nature Scope, Volume 2, Number 4, Amazing Animals, Part II." Includes a glossary of terms, a list of 23 questions about the volume's articles, a bibliography, and a cross-reference of articles from "Ranger Rick" magazine which deals with the same animals in this volume. (TW)

Explores the relationship between teaching and socialization through a case study report of the classrooms of three junior-high science teachers. Provides a brief characterization of socialization and the substance of science teaching and discusses the factors which appear to be relevant to these characterizations. (ML)

Explores the issue of the consistency of use of students' conceptions across different tasks which probed understandings of aspects of pressure, heat, and biological evolution. Findings indicate that children have alternative frameworks for all investigated areas. (ML)

Describes several hands-on science activities which focus on the use of apples. Suggests several ways of using apples to teach classification. Proposes a field trip to an orchard as a culminating activity. (TW)

Presents a model for planning the measurement of physical quantities. Provides two examples of optimizing the conditions of indirect measurement for laboratory experiments which involve measurements of acceleration due to gravity and of viscosity by means of Stokes' formula. (ML)

Discusses a study that examined which reasoning patterns are necessary for success in high school chemistry. Based on student (N=170) scores from the "Classroom Test of Formal Reasoning," it was revealed that students who use formal reasoning patterns are capable of greater achievement in chemistry. (ML)

Describes a technique which gives an automatic and accurate assessment of photosynthetic oxygen liberation with graphical results available immediately. This program takes readings from an oxygen electrode and a photocell simultaneously. The types of results and unique features of the technique are discussed. (ML)

Offers perspectives on the need for secondary science curriculum reform. Discusses curriculum issues in terms of four stages which include: the nature of science; principles of curriculum design; pupils needs and entitlements; and practical proposals for exploring curriculum models. (ML)

Provides descriptions and background information on: the use of workcards; Piaget and science curriculum analysis; a case for integrated science; the mechanism of aqueous bromination; integrating science/mathematics with language arts; and energy education. (ML)

Reports on a content analysis of 14 textbooks on endocrinology. Using thyrotoxicosis as the content maker, the study indicated major differences between books with regard to the information provided and the number of words devoted to the subject. Suggests that medical teachers selecting textbooks be aware of such differences. (TW)

Examines the role of ecology in science instruction and offers suggestions for integrating it into an existing curriculum. Discusses the value of field work and explains the different approaches and difficulties associated with ecological field studies. Highlights the advantages of using the local environment. (ML)

Describes a laboratory experiment that is designed to aid in the understanding of the fundamental process involved in gas chromatographic separations. Introduces the Kovats retention index system for use by chemistry students to establish criteria for the optimal selection of gas chromatographic stationary phases. (TW)

Upholds the importance and need for including visuo-spatial skill exercises in science lessons. Provides suggestions for improving students' visualization skills and reviews the approaches that have been successful with students who were poor in visual skills. (ML)

Describes a computer program, "Activation Energy," which is designed for use in physical chemistry classes and can be modified for kinetic experiments. Provides suggestions for instruction, sample program listings, and information on the availability of the program package. (ML)
