Presents three designs for unusual boats that can be powered by flame, water, or sand. Suggests questions about extensions of these designs that could be useful for further exploration of the topic. (DDR)

Argues that doing and learning science are not the same thing. Suggests strategies involving active learning of a nonpractical nature which encourage discussion of science by children working in small groups. Presents examples of less familiar practical alternatives. (JRH)

Some findings about the provision of science education in English secondary schools are presented. The main finding is that despite the introduction of combined science courses, many secondary schools still organize science teaching in years foour and five as separate subjects for some pupils. (Author/CW)

Described is a simple test tube method developed lead analysis of samples of roadside soil. The relationship between the results and the traffic flow indicate car exhausts are the major source of lead pollution. Materials and procedures are detailed. An example of results is provided. (Author/CW)

Described is the manufacture of a superconductor from a commercially available kit using equipment usually available in schools or easily obtainable. The construction is described in detail including equipment, materials, safety procedures, tolerances, and manufacture. (Author/CW)

Provides evidence that explanations provided by qualified science graduates and by writers of textbooks do not necessarily make sense from a scientific or even a logical perspective when critically examined. Suggests that the process of sharing ideas is problematic and teachers and pupils need to examine critically each other's understanding and…

Various aspects of photography using both transmitted and reflected light microscopy are described. Microscope configuration, preparation of samples for photomicrography, and the use of black/white or color film are discussed. (KR)

Ways in which linear lesson sequences can be modified to provide increased opportunities for open-ended activities especially with problem solving are considered. Examples drawn from chemistry and plant reproduction, seeds, and germination are given. (KR)

Presents a review of research into alternative conceptions about the weather. Exposes the need for further research into secondary students' understandings. Argues that some misconceptions are the result of the imprecise use of terms. Contains 16 references. (DDR)

Begins with the procedure and results from an investigation on the effect of fluoride on the reaction between eggshell (substitute teeth) and dilute ethanoic acid. Describes an elegantly modified and improvised apparatus. (DDR)

Presents examples of the types of investigations which exploit the tools now commonly featured in data-logging software. Emphasizes the importance of designing tasks that encourage pupils to think about the data and the principles which underpin worthwhile data-logging tasks. (Author/ASK)

Describes a project in which a British industrial organization, the Boots Company, a family of schools, and the one-year Post-Graduate Certificate in Education (PGCE) teacher training course at the School of Education at the University of Nottingham cooperated in developing science-focused material in the area of Economic and Industrial…

Responds to the argument that science education has to be a purposeful induction going beyond personal experience and personal knowledge. Speculates about what kind of intervention is appropriate and when. Contains 18 references. (DDR)

Discusses the urban myth that "If toast can land butter-side down, it will" as an example of a source of projects demonstrating the use of the scientific method beyond its usual settings. Other urban myths suitable for investigation are discussed. (Author/MM)

Compares phase diagrams relating to the solubilities and melting points of various substances in textbooks with those generated by a spreadsheet using data from the literature. Argues that differences between the diagrams give rise to new chemical insights. (Author/MM)
