Describes a junior high school level exercise using plant pigments as acid-base indicators. (SL)

Presents the transcripts and summaries of presentations given by four secondary school physics educators. Staffing problems, the implications of junior high school science on senior high school physics, and expectations of secondary school physics courses and their instructors are among topics discussed. (CP)

Selection and care of octupuses as aquaria pets are discussed. Photographs of several species are included. (CP)

Examines various meanings ascribed to "integrated science," and explores arguments used to establish the value of an integrated approach for primary and secondary education. (SL)

One thousand twenty-two seventh grade students in country and city schools enrolled in Intermediate Science Curriculum Study (ISCS) programs were the subjects of this study. Differences in learning rates and retention levels were found to be related to pacing, mental ability, and grouping. (CP)

Presents an intermediate level social studies unit dealing with air education, social aspects of aviation, and the importance of aviation to industry and transportation. Includes objectives, twelve activities, and evaluative procedures. (SL)

Provides a cumulative subject index for the SASTA journal. All articles published from its initial publication in June, 1959, to April, 1976 are included. (SL)

Discusses the range of wavelengths of the electromagnetic spectrum considered to be the visible portion. Describes a demonstration designed to help students understand the relation between the wavelength measurements on a spectrophotometer such as the Spectronic 20 and the actual colors of light being used. (TW)

Differentiates between chemical nomenclature and the common ways that substances are named and described. Students should learn the chemical nomenclature so that they will be more observant and objective. Cites examples of student misconceptions based upon their own imagination and logic. (TW)

Explains: (1) use of piezoelectric film (connected to power supply and oscilloscope) to reveal force-versus-time curves of bouncing balls; (2) use of bound wood splints or meter sticks to illustrate tree or tower stability; and (3) apparatus of co-axial discs with connected linking rods and suspended bobs to simulate waves. (DH)

Investigated developmental and/or sex components of energy attitudes using Kuhn's Energy Opinionnaire. Results indicate that changes in student attitudes through grade levels are consistent with cognitive and affective development literature and that sex differences are more pronounced in older students (with females having a more external world…

Discusses: (1) the nature of an attitude toward science; (2) why people have attitudes toward science; and (3) how attitudes toward science can be improved. Also differentiates attitudes from beliefs and behaviors. (DH)

Examined the influence of selected factors on secondary student's performance in practical chemistry for a sample of students and teachers from 39 Nigerian schools. Student participation in laboratory activities and students attitudes to chemistry were identified as being the most important factors affecting performance in chemistry. (ML)

Describes a study that was designed to apply the learning hierarchy paradigm in an instructional unit in high school biology. Findings indicated that regardless of the pupils' sex or the type of school, students taught the hierarchically organized learning task achieved significantly higher than students whose learning task was not hierarchically…

Reports on a study designed to identify the major factors that lead students to anticipate a major in chemistry. Findings indicated that students' recognition of a high aptitude for science, the influence of a high school chemistry or science teacher, and laboratory experience contributed to their decision. (ML)
