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)

Describes exercises for students to estimate the magnitude of energy available through solar power, wind, atmospheric electricity, heat capacity of air, and latent heat of air. (SL)

Discusses student difficulties in understanding the concept of chemical equilibrium. (SL)

Compares student achievement and retention scores of secondary school chemistry students who were involved in: (1) learning-for-mastery, (2) personalized system of instruction and (3) control (independent study) modes of remediation work. Higher retention and more objectives were recorded by the learning-for-mastery group. (CP)

Assesses the history and current trends in astronomy education. Emphasis is placed in precollege science education. Recommendations to remedy the current low emphasis on astronomy in the secondary education curriculum are advanced. (CP)

The authors illustrate the magnitude and application of the concept of a "googol" (ten raised to the one hundred power) in searching for entities that exist in such number. (MN)

Discusses various chemical aspects of nutrition and food. (SL)

Describes four experiments in mechanics which utilize a tennis ball serving machine. (SL)

Describes experiments and apparatus used to study the interaction of falling water drops on water surfaces and the collision between pairs of drops. (SL)

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)

Investigated was the development of word associations of physics students from age 12 to university graduates. Results indicated response availability increased with age, irrespective of science/nonscience distinction, but that associative indices could be useful as tools in studying early stages of learning. (SL)

The following variables were correlated with attitudes toward science: school type, future specialization, curriculum, sex, achievement level, and cultural background. Only the curriculum variable did not correlate significantly. (MLH)

The Centre's functions are described. A flow diagram, developed for the Scottish Integrated Science Course, showing a modular approach to science for mixed ability or low ability students is given. This course is intended for students in their first two years of secondary education. (AJ)
