Fourteen basic experiments in mechanical engineering, intended for use at the sophomore level, are presented. The experiments are described as open-ended in order to give students the opportunity to discover the importance of stable operating conditions. The concept of experimentation is introduced and there is an interrelation between theory and…

This guidebook provides information related to developing laboratories for an introductory college-level course in mycology. This information will enable mycology instructors to include information on less-familiar organisms, to diversify their courses by introducing aspects of fungi other than the more strictly taxonomic and morphologic, and to…

This reference guide is designed to organize and suggest acceptable practices and procedures for dealing with safety in elementary science instruction. It is intended as a reference for teachers, administrators, and other school staff in planning for science activities and in making daily safety decisions. Topics covered in the guide include: (1)…

This reference guide is designed to organize and suggest acceptable practices and procedures for dealing with safety in the area of science instruction. It is intended for use as a reference for teachers, administrators and other school staff for planning science activities and to assist in making safety decisions in a situational context. This…

This laboratory guide for college chemistry students illustrates scientific equipment used in introductory chemistry courses. Common laboratory procedures are diagrammed with the intention of promoting the safe use of equipment. An index is included to facilitate finding the necessary information. (SA)

Investigated was the effect of different types of laboratory reports on measured outcomes of the Chemical Education Materials Study (CHEMS) Chemistry. Compared were procedures using essay laboratory reports, mimeographed laboratory sheets prepared by the investigator and completed by the students, the laboratory manual for the course completed by…

This document provides evaluation data for the "Mathematics Laboratories for Disadvantaged Students" project. The project was designed to provide mathematics instruction for under-achieving students in grades 5-8. The mathematics laboratory was used by each student for one hour per day five days a week. Each student had his own schedule…

The manual is designed to help the elementary level teacher provide some of the information and experiences needed by students in making vocational decisions. Some of the information deals with simulated experiences, in-school work, and field trips, stressing action with a minimum of theory. Other parts of the manual cover a different phase of…

Basic knowledge about Skylab experiments is presented in this book for the purpose of informing high school teachers about scientific research performed in orbit and enabling the teachers to broaden their scope of material selection. The seventh volume deals with the ability of the Skylab crew to live and work effectively in space. The content is…

This is a series of four units introducing the concepts of solids, faces of solids, points, lines, and planes. Emphasis is placed on the discovery approach with a maximum of manipulation and experimentation on the part of the children. Each unit has suggested activities that include games, individual projects, worksheets, and discussion questions.…

This instructional unit uses an intuitive approach in introducing the concept of congruent transformations. Extensive use is made of worksheets and manipulative methods. In the latter stages, the SSS, ASA, and SAS theorems are presented. The unit concludes with geometric proofs requiring the use of the fact that corresponding parts of congruent…

Computer-assisted instruction (CAI) has proven useful in teaching chemistry instrumentation techniques to undergraduate students. The work completed at the time of this interim report has clearly shown that a general purpose laboratory computer system, equipped with suitable devices to allow direct data input from experiments, can be an effective…

Indicates how the gas laws can be derived and taught to high school and college physical science classes by using the guided-discovery method. (LS)

Explains: (1) use of piezoelectric film (connected to power supply and oscilloscope) to reveal force-versus-time curves of bouncing balls; (2) use of bound wood splints or meter sticks to illustrate tree or tower stability; and (3) apparatus of co-axial discs with connected linking rods and suspended bobs to simulate waves. (DH)

Presents some strategies that have been used to overcome problems in instructional areas of introductory biology programs. Focuses on maintaining an emphasis on inquiry, developing the process of science, the design of process laboratory activities, reducing cookbook laboratory orientation, and educating staff. (CW)
