Describes various techniques for conical chromatography together with advantages and disadvantages. (DF)

Twelve new experiments in biology are described by teachers for use in classrooms. Broad areas covered include enzyme action, growth regulation, microscopy, respiration, germination, plant succession, leaf structure and blood structure. Explanations are detailed. (PS)

This transition, observed with an inexpensive ultraviolet photometer, is a potentially useful experiment for an advanced freshman class because it introduces several concepts of general physical interest. (DF)

In this second article on thin layer chromatography six kinds of experiments are suggested for science teachers to use in schools. (PS)

Programs for students, teachers, and parents that concentrate on human development, self-understanding, and the problems of young people are described. (DB)

Discusses the use of an integrated circuit operational amplifier in an introductory electronics laboratory course for undergraduate science majors. The advantages of this approach and the implications for scientific instrumentation are identified. Describes a number of experiments suitable for the undergraduate laboratory. (Author/DF)

Describes a program that attempts to bridge the gap between class lectures and laboratory. Students are involved in individual investigations. Effective use of undergraduates is made for instructional purposes. (PS)

An unusual experiment in Rochester, New York, shows the value of student-centered learning in today's inner-city schools. (Author)

Research performed while Shannon Moeser was on a Science Scholarship of the National Research Council (NRC) of Canada, and forms part of this author's doctoral thesis submitted to McGill University. Research also supported by an NRC grant to Mr. Bregman. (VM)

Study based on a master's thesis submitted by L. Gartman to Ohio State University. (VM)

An experimental procedure to increase children's rate of hand-raising is reported. The procedure was tired with 240 grade school children and is held to be effective. (DM)
