The philosophy, structure, and organization of a chemical engineering (ChE) process laboratory are discussed. The laboratory emphasizes the oral and communication skills of students who are part of groups that resemble an industrial process research and development group. An annotated list of students' experimental projects is included. (JN)

Suggests a study of plant dyes as a way of stimulating student interest and enthusiasm; provides an example of a student report on this subject. (GS)

The advantages of using invertebrates in teaching physiological principles are discussed. The ability to illustrate with greater clarity physiological principles, the range and variety of physiological processes available for examination, and the unlimited possibilities for student research are topics of discussion. (KR)

Describes a student field project involving the estimation of a maximum rate of erosion for a local area. Identifies the factors influencing erosion and outlines the method of investigation. (GS)

Describes an attempt to incorporate research into laboratory work in an introductory ecology class and a senior seminar. The investigation involves the examination of rhythms of food consumption and circadian activities in humans. (GS)

These guidelines are intended to assist high school psychology teachers in safeguarding the rights and welfare of students and experimental subjects while promoting high-quality instruction. There are three sets of guidelines. The first set deals with the use of animals in school science behavior projects. The major goal of such projects should be…

Describes differences in the construction of a colorimeter and a photometer. Gives examples of ways in which light-measuring instruments can be used by biologists. These examples can be used either as class experiments or as individual projects. (GS)

Explains a series of experiments that increased students' awareness and understanding of activation energy, reaction transition states, rates of reaction, provided a neat example of the diagnostic utility of infrared spectroscopy and furnished insight into the accidental research situation. (Author/GS)

Discusses the use of an individually designed experiment for a chemical engineering laboratory course. Lists main ideas of the method. Provides an example of the experiment including ways to answer the questions and extensions. (YP)

Provides a collection of data on the mechanistic aspects of inorganic chemical reactions. Wherever possible includes procedures for classroom demonstration or student project work. The material covered includes gas phase reactions, reactions in solution, mechanisms of electron transfer, the reaction between iron III and iodine, and hydrolysis. (GS)

Presents directions for constructing a hair hygrometer for detecting moisture in the air, outlines factors related to human space flight and reaction time, and explains the construction and use of a visual aid for map work. (GS)

Describes a method utilized at Iowa State University for teaching a biochemistry laboratory course for non-majors involving the use of student independent projects and experimental choices. (BT)
