Reviews Apple computer science programs that are useful in a laboratory setting. Includes laboratory simulations, uses of Apple as a functioning lab instrument, and dissection programs. (ML)

Describes a simple thermodynamics experiment recommended for use in beginning chemical engineering laboratory courses. Outlines the theory behind the experiment, which determines the specific heat of a liquid. Discusses the construction, operation, and maintenance of the apparatus involved, along with the experimental procedure. (TW)

Discusses the possibility of having chemistry students do their own computer programing that could then be used to solve problems in general chemistry. Describes such an effort at Eastern Washington University. Provides examples of some of the student programs and printouts. (TW)

Explains practices and activities related to measurement, observation, and problem solving/practical investigating in British science classes. Provides three physics investigations and assesses their instructional potential and effectiveness with students. (ML)

Discusses the commonly held misconceptions on heat and examines potential contributing factors. Defines and provides examples of internal energy and heat. Suggests approaches to the teaching of heat for secondary level students. (ML)

Contains 31 activities and experiments from the biological and physical sciences. Addresses such areas as reproduction, biotechnology, ecology, proteins, nitrates, aerosols, metal crystallinity, circuit boards, and photoswitching. (ML)

Tree-ring analysis in geomorphology can be incorporated into a number of undergraduate methods in order to reconstruct the history of a variety of geomorphic processes. Discusses dendrochronology, general principles of dendrogeomorphology, field sampling methods, laboratory techniques, and examples of applications. (TW)

Provides suggestions for two exercises designed to assist and involve students in understanding chemical concepts. Includes a laboratory experiment for determining the Ksp of a saturated solution of calcium sulfate and a scheme for naming oxyacids and their salts. (ML)

Describes a study which examined teachers attitudes about the value of practical work, attitude changes from previous studies, how teachers' aims relate to their teaching emphasis, and the differences between teachers who teach for practical exams and those who use teacher assessment of practical work. Presents methods and results. (CW)

Discusses how teachers turn an idea into a meaningful lesson. Suggests class brainstorming, using community resources, library searches, and further classroom activities. (YP)

Introduced is a project for constructing a can device for a race. Discussed are some applications for teaching physical science. A diagram of a can device is included. (YP)

Presents the results of a comparative study of Canada and Israel. Science achievements based on data collected in the Second International Science Study are examined. Also the intended and translated curriculum are considered. The populations of the study, results of the study, and the similarities between students are described. (CW)

Presents as part I of a two-part series a study involving the intercellular transfer of bacterial DNA that codes for the resistance to antibiotics. Demonstrates to students that such transfers occur. Discusses laboratory procedures, materials and results. (CW)

Describes two experiments for demonstrating the properties of osmosis and semipermeable membranes. Gaseous and liquid osmosis are studied through the use of common laboratory chemicals and equipment. Offers explanations for the phenomena with diagrams. (ML)

Reports two methods for interesting children in chemistry. Describes a method for producing large soap bubbles and films for study. Examines the use of simple stories to explain common chemical concepts with example given. Lists titles of available stories. (ML)
