Background information, laboratory procedures, and a discussion of the results of an experiment designed to investigate the difference in energy gained from the aerobic and anaerobic oxidation of glucose are presented. Sample experimental and calculated data are included. (CW)

Discusses a laboratory course to familiarize mechanical engineering students in the use of electronics and computers. Describes the objectives, laboratory facilities, lecture topics, projects, and laboratory exercises for the course. (YP)

Described are the composition, design, administration, and evaluation of practical examinations. A table of the composition of biochemical unknowns for analysis in practical examinations is included. (CW)

An activity is described in which students learn modeling skills by creating concrete models with familiar objects. Teaching methods, materials, procedures, and outcomes are discussed. (CW)

Activity suggestions for the months of September and October are provided in a calendar format. In addition, two activity sheets, which provide detailed information for studying the moon and the alphabet including materials, and procedures are provided. (CW)

Discussed are the uses of sea urchins in research and their usefulness and advantages in the classroom investigation of embryology. Ideas for classroom activities and student research are presented. Lists 25 references. (CW)

Described is an activity in which the transmission of disease is simulated by the students in the classroom using common solutions. Discussed are materials, preparation, procedures, and questions for classroom discussion. (CW)

Presented are two demonstrations including a variation of the iodine clock reaction, and a simple demonstration of refractive index. The materials, procedures, and a discussion of probable results are given for each. (CW)

Described is an experiment which illustrates valence isomerization, the trapping of a reactive intermediate and retrosynthetic analysis applied to the Diels-Alder reaction. Included is a background discussion, experimental procedures, and a discussion of the analysis. (CW)

A laboratory experiment designed as a model for studying enzyme activity with a basic spectrometer is presented. Included are background information, experimental procedures, and a discussion of probable results. Stressed is the value of the use of Nuclear Magnetic Resonance in biochemistry. (CW)

Described is an apparatus which can be made for student use in performing organic qualitative analysis. The flask replaces the need for more expensive equipment. Discussed are reagents, equipment preparation, experimental procedures, and sample preparation. (CW)

Two exercises on the dispersal of tree seeds by the wind are presented. Procedures, equipment, and analysis for the still air and wind dispersal activities are described. Nineteen references are listed. (CW)

The construction of a wooden model of the musculoskeletal system which can be used to investigate the physical properties of muscles without sacrificing laboratory animals is presented. Six activities are included with answers. Additional activities are suggested. (CW)

Described is a procedure by which the performance of chemical hoods can be tested. This procedure uses a mixture of dry ice and water to create a "smoke" for use in the test.
