Described are five physics experiments utilizing inexpensive, readily available materials or materials normally found in a physics laboratory. Included are investigations of electrical charge, sound detection, thermal expansion, doppler effects, and the cycloid. (SL)

Describes high school physics projects for investigating road safety problems. Includes diagrams of laboratory apparatus and explanations of experiments. (CS)

Describes a lighted demonstration apparatus for representing the distribution of electrons, protons and neutrons in an atom. Also includes experiments with ice, forces, microscopes, spectra, and geological modeling. (CS)

Argues against Hillman and Sartory's views of cell structure (EJ242880), pointing out that they are erroneous in their analysis of the motives and working methods of the scientific community, in their total rejection of information coming from electron microscopy, and in their claim that lysosomes and endoplasmic reticulum are imaginary. (DC)

Describes outdoor biology activities in a woodland area at a private boys school in England. Activities included studies of areas within the woods, winter trips, and wood and pond animals. Includes comments on preparing for and teaching the activities. (Author/JN)

Suggesting a distinction between student attitudes toward science as a school subject (SUBATT) and toward the social implications of science (SOCATT), reports results of a study using various measures focusing on SOCATT and SUBATT of approximately 2,200 students in 33 schools, including findings related to sex differences. (DS)

Discusses distillation of liquid mixtures with the emphasis on experimental work. A number of experiments, intended for chemistry secondary school teachers in the United Kingdom, are included. (HM)

Organized by topic is a reading list for A- and S-level biology. Described are experiments for measuring rate of water uptake in a shoot; questions to aid students in designing experiments; rise of overhead projection to demonstrate osmosis and blood cell counting; and microbial manufacture of vinegar. (CS)

Describes a three-dimensional computer modeling system for biological molecules which is suitable for sixth-form teaching. Consists of the modeling program "RasMol" together with structure files of proteins, DNA, and small biological molecules. Describes how the whole system can be downloaded from various sites on the Internet.…

Discusses the traditional approach to writing science textbooks, the situation preceding the National Curriculum, and the effect of the National Curriculum. Summarizes the historical content of current science textbooks including biographical narratives and human interest material, accounts of scientific discoveries, and the history and…

Describes a cut-out 3-D DNA model, which can be used to teach about DNA structure. (YDS)

Explains how students' alternative conceptions about curriculum topics interfere with classroom learning. Describes the Royal Society of Chemistry's Teacher Fellowship Project entitled "Challenging Misconceptions in the Classroom," which develops classroom materials to diagnose and challenge specific alternative conceptions. Uses key…

Describes the problems involved in teaching astronomy so that teachers can be informed and forewarned. Focuses on the fact that teachers are not likely to be familiar with the content and unfamiliar with the problems associated with teaching the content. (DDR)

Outlines a safer alternative to the traditional physics demonstration known as the "kicking wire" experiment. The new method eliminates the use of an open dish of mercury but is less dramatic in the visible effects it produces. (DDR)

Argues that science teaching should place more emphasis on linguistic explorations which provide an opportunity for students to develop proto-concepts that enable the development of scientific thinking. Contains 16 references. (DDR)
