Described is a cooperative content study group approach to learning that minimizes individual student memorization and maximizes student interaction. Directions for preparing instructional materials and implementing cooperative home teams, a sample home team worksheet, sample test and study items, and hints and suggestions are included. (KR)

A classroom experiment is proposed in which students can mate a banded or spotted convict cichlid with a pink convict cichlid and observe the markings of their "children" and "grandchildren" as a way of illustrating Mendel's Laws of Dominance and Segregation. (MN)

An annotated bibliography of astronomy activities is provided. Appropriate level for suggested activities is indicated. (MK)

Boyle's Law and basic relationships between volume and pressure of a gas at constant temperature are presented. Suggests two laboratory activities for demonstrating the effect of temperature on the volume of a gas or liquid. (CS)

Moh's scale for determining the hardness of substances is explained. Four classroom exercises are suggested. (MK)

Discusses and clarifies the confusion arising from the use of the terms "mass,""volume,""matter,""mole," and "Avogadro's number." Suggests three laboratory activities concerning mass, volume, and number of particles in a given volume. (CS)

Presents data from a study to show that a mystique effect can occur for classroom students. Recommends that teachers provide orientation session before content objectives are taught. (CP)

Describes an activities approach to the Man-Made World that is organized as a series of mini-courses to enable disadvantaged and unmotivated students to achieve a degree of technological literacy. (GS)

Advocates the use of manipulative and observational science activities as the basis for children's experience stories that can be used as material for reading and language arts programs. (CP)

Construction of a laboratory area suitable for laser experiments and the creation of holograms is described. (CP)

Details approaches which may be used to present energy related topics to secondary school students. (CP)

This article suggests the use of the circuit box to illustrate the processes involved in the scientific method. Construction and wiring diagrams and a materials list are presented. (BB)

Develops a rationale for integrating oceanography and marine education in land-oriented curriculum at the secondary level. Examples of topics with a multidisciplinary approach are described in the areas of acoustics and music, aquaria, archeology, art, astronomy, literature, careers, ecology, gastronomy, geology, and topics on various aquatic…

Describes the Science Activity Teaching model, which incorporates five teacher managerial behaviors into a model with these subcomponents: focus activity, student instructions, student group activity, synthesizing, and evaluation. This plan provides for the development of fate control, language formation, and social skills. (CS)

Described is an activity designed to make the concepts of experimentation, independent variables, and dependent variables easy to understand by using observable characteristics of several rods to illustrate these concepts. (DS)
