Live specimens are necessary to the teaching of biology because observations of animals during lessons and outside the classroom exert a tremendous influence on a child's developing interest in biology and provide him realistic notions of the animals he studies. Exemplary lessons are provided. (Author/ND)

Discusses the need for a technical teacher who could help college students working in geology laboratory and field settings. The duties and qualifications of the technical teacher are also discussed. (HM)

Describes a device for maintaining the proper water level in knife boats during ultramicrotomy. Water levels in troughs are adjusted rapidly and precisely during the cutting process. Illustrations are included. (Author/MA)

Describes a zinc-sawdust mixture effective for cleaning up mercury spills and presents an experiment to illustrate the mixture's effectiveness. (SL)

Discusses the development of materials used in chemical laboratories. (SL)

Numerous examples of devices designed by primary school children are provided. The instructional methodology and classroom setting are also described. (CP)

Smaller amounts of materials are used in organic chemistry experiments as a means of improving air quality in the laboratory. Presents a preliminary study of the emissions from selected processes and the mixing of these emissions within the laboratory atmosphere. (JN)

Discusses planning for non-structural laboratory items, such as desks, instruments, and high purity water systems. (MLH)

Describes an earth science laboratory approach designed to involve students in an ongoing method of solving problems; student questions and discussion provide the basis for laboratory exercises. (Author/SL)

Describes the use of the magnetometer in an introductory undergraduate geology course. (SL)

Uniform illumination levels in the classroom and focused brightness on the "teaching wall" made good sense for students in Henry Ford's era. If you were training to take your place on the assembly line, you needed to focus on the work at hand and ahead to your supervisor, but the future no longer belongs to students who look only straight ahead.…

In the applications of instrumental analysis lessons, advanced instruments with the needed experiments are needed. During the lessons it is a fact that the more experiments are performed, the more learning will be. For this reason, experiments that do not last long and should be performed with more simple instruments and that increase students"…

One of the major challenges facing people committed to Teaching Safety in High Schools, Colleges, and Universities is keeping up with both the wide range of relevant technical information about potential hazards (ranging from fire protection to chemical hazards to biological issues) and the ever-changing world of safety regulations and standards.…

This document contains an annotated bibliography aimed at the teaching of the physical sciences at the tertiary level to those who wish to become more informed about teaching related research evidence and undertake science education research. The bibliography offers an overview of teaching and learning in the physical sciences and key references…

Feedback from assessments should be the foundation for improvements students make in their lab work. Therefore, in this study, a standard rubric that reflected the scientific method was employed as an intervention to assess student lab write-ups. Students preformed three labs all based on consumer research. The first lab was completed without the…
