"Science Work-A-Text" combines a text and workbook approach to studying/teaching grades 1-6 elementary science. Five major themes (living things; health/nutrition; planet earth; the universe; matter and energy) are covered at each grade level. Major focus of the series is on reading and content rather than process. (Author/SK)

Discussions are presented for implementing photoacoustic spectroscopy as a technique for describing the photoacoustic effect. This technique makes it possible to study optical absorption in samples which are usually difficult to study. It is suggested that this approach makes understanding of the photoacoustic effect accessible even at the…

Pictorial contents of biology textbooks are examined as factors to be considered in assessing textbook readability. Includes data indicating that effect of color upon the observations and interpretations of photographs varies with the child's ability. Implications for textbook selection procedures are discussed. (CS)

Describes a clock reaction resulting from the reaction of paraquat with base. (CS)

This article reviews and compares five recent secondary science texts: Addison-Wesley Life Science (Gr. 7-9); Prentice-Hall Life Science (Gr. 7-9); Scott Foresman Biology (Gr. 9-12); Biology: Living Systems (Gr. 10-12); and Biology: The Science of Life (Gr. 10-12). (SJL)

Discusses the applications of thin films in energy, optics and electronics. The use of thin-film technologies for heat mirrors, anti-reflection coatings, interference filters, solar cells, and metal contacts is included. (HM)

Described is a method for bringing the sea into the classroom by setting up a saltwater aquarium. Included is selection of an aquarium, filtering systems, water (whether natural salt or synthetic sea salts), bottom materials, setting up an aquarium, system stabilization, stocking an aquarium, and maintenance of the aquarium. (DS)

Provides information regarding underwater vision. Includes a discussion of optically important interfaces, increased eye size of organisms at greater depths, visual peculiarities regarding the habitat of the coastal environment, and various pigment visual systems. (CS)

Describes electroreceptivity in fishes, including information on electric signals in water, electroreceptors, electric organs, electric sense in weak-electric fishes, electrolocation, electrocommunication, and evolutionary considerations. (CS)

Relates the Victorian field sport of shooting to the development of the field science of ornithology in the nineteenth century. (CS)

Describes methods for using the high-resolution electron microscope in conjunction with other tools to reveal the identity and environment of atoms. Problems discussed include the ultimate structure of real crystalline solids including defect structure and the mechanisms of chemical reactions. (CS)

Described is an apparatus for determining the Curie temperature of a Ferromagnetic material which enables large specimens to be heated up to a maximum of 1100K in 20 minutes. Included is the theory, magnetic circuit apparatus, electrical circuit, and results using this apparatus. (DS)

Suggests how elementary teachers can go beyond the science text and use commonplace materials to create science experiments which sharpen students' observational skills and their ability to formulate testable hypotheses. Seven experiments are outlined, using materials such as paper, cotton socks, and mayonnaise. (SJL)

Discusses the electric field line pattern for four equal charges of the same sign placed at the corners of a square. The electric field intensity and the point of equilibrium are interpreted, taking into account three dimensions. (HM)
