Four mathematics activities with extensions are presented. The focus is on using and interpreting data as a basis for integrating mathematics, science, and social studies. Parent participation is encouraged. Reproducible sheets are included. (KR)

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)

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)

Presented are the results of a study of the effects of peer-led tutoring groups on achievement in college chemistry. Supplemental instruction was effective in increasing students' achievement in chemistry as measured by final grades in chemistry and responses to a questionnaire. (CW)

Discussed are hazardous substance regulations in Great Britain which effect science teaching at the secondary and college level. Included are background information, immediate implications for schools and colleges, and risk assessments concerning biology classrooms. The responsibilities of Local Education Associations are highlighted. (CW)

This paper gives a definition of communicative macro-tasks within a situational and functional approach to the teaching of foreign languages, and particularly English, to science, technology, and engineering students. It also attempts to present a typology of such macro-tasks and describes possible classroom applications. (Author/YP)

Discussed is a program created to serve as an instructional tool for teaching basin analysis. Described is the use of the program for interpreting plots resulting from backstripping methods. Included in the discussion are implementation, applications and availability of the "Subside!" program. (CW)

Reported are the results of a survey conducted to identify which analytical methods are most commonly used in nonacademic analytical laboratories. Laboratory supervisors' ratings of various aspects of chemical education are included. (CW)

Described is an activity in which a computer is used to acquire temperature and humidity data useful in investigating transpiration in plants. Materials and procedures are discussed and examples of results are presented. Factors which influence the rate of transpiration are discussed. (CW)

Included in this section are articles on the following topics: science education for pupils with learning difficulties, the Engineering Council, differential achievement in early childhood according to sex, a peer tutoring program, and suggestions for involving students in recording their own achievement. (CW)

Presented is a computer simulation called "The Great Chemical Bead Game" which can be used to teach the concepts of equilibrium and kinetics to introductory chemistry students more clearly than through an experiment. Discussed are the rules of the game, the application of rate laws and graphical analysis. (CW)

Presented are three computer projects: vector analysis, electric field intensities at various distances, and the Biot-Savart law. Programing suggestions and project results are provided. One month is suggested for each project. (MVL)

Examples of sets of questions on library readings designed to lead students into articles and emphasize important information and associated literature are presented for introductory geology courses, historical geology, structural geology, mineralogy, and petrology. (Author/CW)

Presents two demonstrations using the overhead projector: (1) describes how to build a projecting voltmeter and presents uses for the classroom; and (2) investigates the color of fluorescent solutions by studying the absorption and transmission of light through the solutions. (MVL)
