Discussed are the two sides to the question of laboratory dissections. Alternatives to dissection are proposed as well as the importance of incorporating dissections in a science curriculum. (KR)

Outlined is a specific computer application which can be used to analyze data on plant community composition from the point quarter sampling method. Procedures, examples of spreadsheets prepared in this manner, and evaluation of the activity are presented. (CW)

Described is a study in which scientific research on the Gulf of Maine was used as a framework for establishing the extent of Maine students' knowledge about the nature and management of marine systems. Methodology, frameworks, data analysis, comparisons with other standardized tests, and results are presented. (CW)

Presented is an experiment which demonstrates principles of experimental design, solubility, and crystal growth and structure. Materials, procedures and results are discussed. Suggestions for adapting this activity to the high school laboratory are provided. (CW)

A paper model which is designed to give students a hands-on experience during lecture and blackboard instruction on DNA structure is provided. A list of materials, paper patterns, and procedures for using the models to teach DNA structure and replication are given. (CW)

The use of living animals in the classroom is discussed. A checklist of ideas to remember when considering housing animals in the classroom is provided. (CW)

Described is an interdisciplinary program designed to coordinate the physics and calculus courses for seniors in a Massachusetts high school. Target audience, benefits, team coordination, and impact are discussed. A list of suggested crossover topics is provided. (CW)

Described is the use of the microcomputer and interfacing equipment to obtain weather data from meteorological satellites. Equipment necessary for this type of remote sensing, including constructing and/or obtaining the necessary hardware and software is discussed. Ideas for the integration of this material into the curriculum are presented. (CW)

Three reports are presented including "Do Practical Subjects Encourage Understanding of Science?"; "What Is an Anti-Racist Atom?"; and "Taking the Plunge with Role Play. Departmental In-Service Using SATIS Materials." (CW)

Described is a simple test which uses micro- and macro-observations of onion root tips to demonstrate mutagenic and other toxic effects of various contaminants. Discussed are materials, methods, microscopic procedures, and applications of this activity. (CW)

Described is the generation of a scale model of the solar system and the milky way galaxy using a computer spreadsheet program. A sample spreadsheet including cell formulas is provided. Suggestions for using this activity as a teaching technique are included. (CW)

Problem solving is defined and characteristics of good problem solvers are highlighted. The cognitive processes used in problem solving are discussed. Suggestions for methods which can be used to teach problem solving are provided. Research implications from mathematics education are listed. (CW)

Contrasted are DNA viruses, RNA viruses, and RNA retroviruses. The structure, genome, and replication of retroviruses are discussed. The discovery, structure, and action of the HIV virus are described. A list of 17 references is included. (CW)

Described is a project designed to give students an understanding of the environmental implications of current energy practices and a chance to participate in a project that may have a measurable impact on environmental quality. Suggestions for the integration of this project into high school science classes are provided. (CW)

Students' conceptions of the concept of force are discussed. Possible problem formats and exercises are presented. The need for many formats and variations to help students' resolve their conflicting ideas about physics concepts is stressed. (CW)
