Describes a funding simulation for use with college students in an advanced experimental psychology laboratory. Students write an original research paper and submit it to the professor--the "funding agency"--as a grant proposal. Projects are funded with grade points with which the student director purchases help from unfunded classmates. (RM)

A list of demonstrations of discrepant events which have been found to stimulate the curiosity of students in science at the secondary school level are presented. A brief description of the materials and procedures for 15 of these demonstrations is outlined, with short explanations of concepts and principles involved. (MP)

Describes a laboratory exercise to demonstrate enzyme activity using gelatin and meat tenderizer. The exercise is adaptable to any grade level. (MA)

Describes methods for studying the direct effect of thyroid hormones on the induction of metamorphic change in amphibians. (CS)

Describes the objectives and format of a mathematics course offered at Carl Sandburg Community College (IL) which supplements classroom experiences with laboratory experiments. Enumerates the educational benefits of the laboratory approach and discusses the students' evaluation of the course and its format. (AYC)

The uses of isoenzyme assays are reviewed as they relate to solutions of practical problems. Emphasizes their use of diagnostic tools in medicine, specifically in cardiac profiling. Suggests that principles of isoenzyme assays readily demonstrate molecular structure, acid-base equilibria, kinetics, and electrochemistry to general chemistry…

Presented is a short discussion of factors causing color changes in animals. Also described is an activity which may be used to demonstrate the response of amphibian skin to a melanophore stimulating hormone in high school or college biology classes. (PEB)

Describes an experiment suitable for an instrumental analysis or quantitative analysis course. (BB)

This experiment can be used as either a demonstration or a laboratory activity illustrating the principles of affinity chromatography to purify an enzyme. (BB)

The role of laboratory experience in professional education is discussed. Although laboratory experiments are often expensive and demanding on faculty time, they can offer a unique experience to the veterinary medicine student. (BH)

Demonstrations of Boyle's Law and of the relationship of gauge pressure and atmospheric pressure are presented. (BB)

Presents a laboratory experiment that was developed to acquaint physics students with field-effect transistor characteristics and circuits. Computer-drawn curves supplementing student laboratory exercises can be generated to provide more permanent, usable data than those taken from a curve tracer. (HM)

Describes a laboratory demonstration that can be used to convert an analog quantity into frequency, which can then be converted into a binary measure using either an oscilloscope or a frequency counter. (MA)
