Provides instructions for constructing a model of a working thermostat and suggests several student activities using the model. (DS)

During the late sixties and early seventies a new nontextbook, lab-centered approach was used in science instruction in elementary grades. With the arrival of the eighties, science curriculum has come full circle, and new science textbooks with corresponding curriculum guides are being adopted. (JN)

Presents six selected middle school science notes which could be used in school science courses. Each includes the name of the author and a description of activities presented. (HM)

Reviews four science curriculum materials. "Human Issues in Science" presents social consequences of science and technological developments. "Experiences in Science" contains duplicating masters to supplement basic science programs. "Outdoor Areas as Learning Laboratories" includes activities for local environments. "The Science Cookbook" uses…

Lists the materials and outlines the procedures for mounting maps on cloth to make the maps weatherproof, more durable, and easier to handle. (GS)

Discusses the problem of the shortage of engineers capable of designing advanced integrated circuits (IC) and presents some suggestions for increasing the number of IC designers in universities and semiconductor companies. (HM)

Lists the materials and describes two procedures, for demonstrating the solubility and complex ion equilibrium of silver(I) compounds. Indicates possible hazards and proper disposal. Suggests several homework problems. (JN)

In these studies, the structured content overview positively affected students' upper and lower level comprehension scores as compared to either vocabulary preteaching or control (no prereading) treatments. Vocabulary preteaching appeared to be more important with science than with history materials. (Author/SJL)

Discusses how the frequency domain (line widths) and time domain (coherent optical transients) are related to the concept of transverse relaxation time in the study of high resolution optical spectroscopy. (HM)

Describes the status of teaching physics at Xaverian High School, Brooklyn, New York. The enrollment of students in physics, instructional materials, laboratory activities, and coordination between physics and mathematics are described. (HM)

The Assessment of Inquiry Potential (AIP) instrument, a tool for classifying scientific materials on the basis of their potential for inquiry learning, is presented and discussed. (MK)

Presents six short articles on middle school science activities. Each includes the name of the author and a description of activities suggested. (HM)

Evaluation criteria for selecting an elementary school science program are given. The administrator's and teacher's roles are discussed. An evaluation instrument which provides a systematic approach to comparing science materials is given. (SA)

Discusses the energy processes required to sustain life. Diffusion, oxygen transport, oxygen in arterial blood, and carbon dioxide transfer are the topical subdivisions discussed. (SA)

Experiments designed to help undergraduate students gain experience operating instruments and interpreting gas chromatography and mass spectrometry data are presented. Experimental reagents, procedures, analysis, and probable results are discussed. (CW)
