Suggests that discussion of the poor eating habits of Americans and its effects on health be included in the biology course. (LS)

Describes a high school botany course in which the students must collect plant specimens, prepare herbarium cards and identify the specimens. (LS)

Studies of the hierarchical attainment of conservation of physics concepts revealed significant differences with respect to age, sex, and grade level in a random sample of seventh and eighth grade students. Conservation of a quantity did not necessarily depend on the prior conservation of its constituent fundamental quantities. (MLH)

Describes the development of a test instrument designed to predict a student's ability to use the processes of science. Seventh grade students took the objective test, which had a significant positive correlation with actual performance on the corresponding subtest of criterion measures. (MLH)

Discusses how the upper secondary science curriculum in Japan has been revised, and reasons for this revision. Describes the objectives and content of the new curriculum. (MLH)

A survey of 45 public high schools in Florida shows an extremely low enrollment of black students in science courses. Suggests that vague career aspirations, parental and counselor roles, and perhaps a certain degree of racism account for the enrollment figures. (MLH)

Provides lesson plans for activities involving a model aircraft laboratory and ground-based surveying. (MLH)

Explains why sucrose does not reduce Fehling's or Benedict's solution while maltose, fructose and glucose do. (LS)

Describes the formation and objectives of the Nuffield Science Teaching Project, and presents results of a study in which 1,723 British secondary schools were surveyed to determine if they use Nuffield science curricula. (MLH)

Three Piagetian tests of formal reasoning were administered to 65 high school biology students after half of this group had been exposed to a training session involving the control of variables. Among the results of this study was that the concrete operational students benefited more from the training session than did the formal operational…

Describes an experiment, using a soap bubble raft, intended to provide insight into the orderly packing of spherical objects and the properties of metallic crystals. Also describes a solubility product experiment which uses barium hydroxide. (MLH)

Reports a study designed to determine if teaching science by inquiry helps students learn by discovery and become less teacher-oriented. (LS)

Offers an approach to the analysis of ecology oriented advertising based on the Essentia Project of the American Geological Institute (ESSENCE) model. Suggests several classroom activities to be done with this topic. (CP)

Reports on the efforts of two groups involved in the formulation of science curriculum for the Least Academically Motivated Pupils (LAMP) in the secondary school. (CP)
