Since the major causes of accidents are carelessness and a negative or apathetic attitude towards safety, this guide was developed to facilitate safe, stimulating science laboratory activities by providing both general and specific safety information presented in 12 sections. Subject areas considered in these sections include: 1)…

This document has been designed as a guide for anyone planning to teach the metric system to teachers, parents, children, or the general public. The handbook has the following sections: (1) Introduction, (2) Rationale and Key Considerations for Measuring with Metric, (3) Philosophy and Methodology, (4) Measurement Activities, (5) Teacher…

This teacher's management guide accompanies a set of five booklets which comprise the basic curriculum for "Mathematics Laboratories for Disadvantaged Students," a nationally validated Title III ESEA project. The project was planned for students who are below their expected achievement level in mathematics. Included in the management…

This document is a descriptive summary of the Georgia Institute of Technology's semiotics laboratory. A review of the goals and objectives of the laboratory is followed by a description of the facilities, including the computer software. The capabilities and uses of the laboratory are outlined for classroom experiments, instructional experiments,…

This paper reports the development, operation, and initial performance evaluations of an electrical engineering laboratory station equipped for computer-guided experimentation (CGE). A practical evaluation of the actual instructional value of two programed lessons utilizing this new system for laboratory instruction and experimentation is also…

The procedures used in the initial development of a Mathematics Laboratory within the Individually Prescribed Instruction (IPI) Mathematics Program are reported. The thesis of the report is that in the development of educational programs, especially those which are complex, attention should be directed both to the design of the program and the…

The history of the use of laboratory work in teaching science is traced from the 18th century to the present laboratory-centered curricula. Major rationales and objectives for laboratory work are presented, and different types of laboratory activities are discussed from the standpoint of learning theories and research findings. Also discussed is…

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)

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)

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 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)
