This inexpensive but informative experiment for undergraduate biochemistry students involves isolating phosphatidyl choline from spinach leaves. Emphasis is on introducing students to techniques of lipid extraction, separation of lipids, identification using thin layer chromatography, and identification of fatty acids. Three periods of three hours…

Presents some introductory experiments involving the reaction between EDTA and several metal ions using metallochromic indicators. The experiments represent familiar reactions and are followed by suggestions for extension into areas of discovery work by students. (Author/SA)

Designed to accompany the student text on respiration, this manual presents instructions on the use of laboratory equipment and presents various experiments dealing with the concepts presented in the text. Thirty-nine laboratory activities are described. Laboratory activities are divided into several parts, each part covering a specific experiment…

Offers challenging work at a higher level of technique than most students meet in elementary laboratory work. Uses a combined weight and volumetric sequence not shown in textbooks. Notes modern rapid balances help lower evaporation loss during weighings. Discusses the balance, weights, and buoyancy considerations. (MVL)

This technical report is in three parts. Part I is a conceptual treatment of communication in which the human being is viewed as a goal-attainment system. The goal-attainment problem is defined as a discrepancy between the current state of the system and a specified goal state. Several forms of the communicative relationship are outlined. Part II…

Discusses the use of a teaching fellows program (undergraduates teaching undergraduates) in a psychology laboratory class. Examines the goals, outcomes, curriculum, and implementation of the laboratory class and how these were impacted through the use of teaching fellows. Includes a table showing curriculum, content area, laboratory activities,…
