Describes a semistructured approach to the laboratory situation in organic chemistry. (Author/PEB)

Directions are given for student learning activities on illusions, shadows, the spectrum, and colors. (DT)

Describes an undergraduate laboratory project involving lecithin which integrates two general aspects of lipid methodology: chromatographic techniques and use of enzymes specificity to obtain structural information. (Author/SLH)

Described is thin-layer chromatography (TLC), a technique that can be conveniently used in the laboratory to generate evidence supporting the principle that degrees of biochemical similarity reflect degrees of evolutionary relatedness among organisms. (Author/PEB)

Discusses the offering of a one-week "fun" lab course designed for students to further their professional competence, offer intellectual enrichment, advance their avocational interests, or provide personal enjoyment. (CC)

Describes the use of laboratory experiments termed hands-on demonstrations that are designed to reinforce the concepts covered in lecture with emphasis on maximizing the sense content (sight, smell, hearing) to improve retention by the student. (GS)

This report addresses the initial phase of a multiphase effort to install Training Assistance Technology (TAT) capabilities on a submarine combat system trainer (SCST), and evaluate their effectiveness during a formal training course. This phase addresses the (1) selection of the trainer and course with which to conduct the evaluation, (2)…

This is the second in a series of guidebooks written for elementary school teachers to help improve their science teaching. The book emphasizes processes of science and creativity as well as science content. The book is divided into three sections--the atmosphere, the lithosphere, and the hydrosphere. Each chapter begins with simple concepts, and…

This is the third in a series of guidebooks written for elementary school teachers to assist them in improving their science instruction. The book attempts to emphasize processes and creativity as well as content. Atoms and molecules constitute the subject matter of the publication. Many experiments and demonstrations are included.

The first article in this publication concerns radio-telemetry temperature studies of homoiotherms and poikilotherms. Radio telemetry reduces the problems related to demonstrating the differences between "warm-blooded" and "cold-blooded" animals; results may be plotted graphically, compared and used to generate classroom…
