A discussion of levers, moments of inertia, fulcrums and forces involved in the action of boat rowing is presented. (CP)

Reviews the methods being utilized to teach Darwinism in English schools. (SL)

Second part of an article describing the use of programmable calculators to solve complex physics problems. (SL)

Second of a two part article reviewing the underlying concepts involving the mole concept. (SL)

Summarizes the main categories of games/simulations and lists games/simulations as to major field (physics, with 23 listed; chemistry, 24; biology, 107), providing information as to address for ordering, category, appropriate age group, number of players, time needed in computer simulation, price. Also listed are books, journals and addresses…

Includes methods for demonstrating Schlieren effect, measuring refractive index, measuring acceleration, presenting concepts of optics, automatically recording weather, constructing apparaturs for sound experiments, using thermistor thermometers, using the 741 operational amplifier in analog computing, measuring inductance, electronically ringing…

Includes methods for using harmonographs in demonstrating motion of pendulums, constructing an electrostatic "bell," inverting mirror images, demonstrating the corrosion rate of steel, demonstrating expansion, studying rate of reaction between magnesium and hydrochloric acid, using matchboxes in science for containers, problem boxes, building…

Introduces project work as a viable alternative to other forms of practical assessment involved with the Nuffield A-level physical science course. Percentages of teacher and student responses to attitude statements concerning project work are reported. (CS)

Proposes that science educators assess their field in terms of approach, achievement, resources, aspirations, and consequences. Projects the belief that science education must find quantitative and qualitative measures for the criteria, lest it be done by external agencies. (CP)

Described is a science program being developed at a high school in Great Britain to cater to the particular needs of females. Curriculum was modified in third, fourth, and fifth examination years to emphasize social nature of science and relevance of science to pupils' lives. Some of the problems encountered with program and selected parts of…

Discusses the need to include studies of reliability and maintainability during the design of any system. Topic areas addressed include availability calculations, complex systems and standby redundancy, availability and malfunction levels, design techniques, fault trees, functional maintenance, and others. (DH)

Suggests mural ecology as an alternative to studying other habitats, providing examples of zonation patterns, food webs, effects of physical factors, and influence of man on mural communities. Also suggests incorporating these topics into ecology courses, offering ideas for field work and comparing mural to traditional ecological studies.…

Repetition of a historical experiment in a school project threw new light on the question of absolute rest. The student experiment investigated whether a particular direction in space could be singled out by a purely terrestrial procedure, while the original experiment investigated the drag coefficient of a solid medium. (JN)

Offers perspectives on the importance and purposes of science education. Emphasis is given to understandings and applications of scientific knowledge. Integration of the science disciplines and an interdisciplinary approach in science instruction are recommended. (ML)
