Describes how some experiments in physics can be presented in class using cheap materials. How to produce an electrostatic charge using a polythene bottle and how to make a tissue paper electroscope using a tin can are among the experiments described. (HM)

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

Considers the strategies of peer group review and concept mapping, both of which faculties in higher education might employ in partnership with schools to reestablish the fundamental role that subject matter knowledge has in science teaching. (DDR)

Reports a mismatch between teacher and pupil knowledge of acid-base chemistry as a result of controversial episodes from three science lessons. Suggests that the teacher's knowledge is guided by textbook information while the pupil's knowledge is based on direct experimental experience. Proposes that classroom activities should support the…

Explores the reasons why data logging is still not an integral part of the science curriculum in the majority of British schools. Suggests some strategies to assist science teachers in taking the initial steps towards utilizing this technology. (DDR)

Summarizes the benefits of using hydroponics in school for investigational work. Lists requirements and includes advice on suitable plant choices. Outlines the various growing systems and growing media and provides suggestions for science investigations using hydroponics. (DDR)

Argues that discussion-based approaches are necessary for the development of positive attitudes to socio-economic and applied aspects of science. Presented are evidence supporting this argument and some examples of appropriate learning materials. (Author/CW)

Conducted classroom observations to determine students' understanding of the nature of science and the intentionality of experiments. Topics discussed include: does science seek to explain, using models, proving that the theoretical explanation is correct, and discussions of different interpretations. Concludes that most students in the 14-16 age…

Describes a small-scale study of a course that placed emphasis on context- and activity-based science. The Salters' science course makes use of a wide range of learning strategies. Author concludes that pupils' interest and enthusiasm for school science may be increased through a combination of using pupil's everyday interests and employing a wide…

The relationship between process and content in children's science learning is discussed. The idea that both aspects are important in learning, especially during practical investigations, and that both should be emphasized are presented. (KR)

A survey of adults that shows considerable misunderstanding of two major ideas--that there is no energy in fuels and burning involves two stages--is discussed. Proposed are fundamental changes in the way ideas about burning are introduced to children. (KR)

Discussed are the division of labor, defenses, genetics and evolution, communication, and navigation power of honeybees. The scientific and cross-curricular themes that can be offered using the economically important honeybee are described. Research that suggests that bees may be flying magnets is also discussed. (KR)

Energy problems that incorporate power generation in hydroelectric, fossil-fuel burning, and nuclear power stations are presented. The burning process and the energy released are discussed. Practice problems and solutions, a summary of various energy units and conversion factors, and lists of thought-provoking energies and powers are included. (KR)

A range of alternative approaches to student work in science is presented. The approaches are illustrated by examples of students' work including cartoons, cards, poems, and posters. A number of audiences other than the teacher is identified as a potential focus for students' written work. (KR)
