Describes the use of cassette tape recordings in preparing freshman chemistry students for experiments in laboratories. The tapes are said to have decreased student anxiety in the laboratory and increased laboratory skills. (SA)

This book contains construction plans of exhibits that have been collected during more than 10 years, and notes for their maintenance, at the Ann Arbor (Michigan) Hands-On museum. It is a useful source of hard-to-find information for exhibit builders, science fair participants, science teachers, students, and home tinkerers. This collection…

Described are some experiments on geotropism that may be done using dandelions. (PB)

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)

This book is provided as a helpful tool in ensuring a successful and satisfying elementary school science fair. The book clarifies the roles of teachers, parents, and students and provides information about types of projects, practical tips, and possible topics for research. Included are short bibliographies, sample forms (which are teacher…

Distillation in the chemistry laboratory is an essential part of a practicing chemists' and a chemistry educators' work. Nevertheless, regardless of the degree of importance in each of the aforementioned professions, few educational studies on teaching and learning distillation exist. In an effort to rectify this oversight, the Department of…

This publication provides administrative, management, supervisory guidance, and other information necessary for successful conduct and support of grades 7-12 science symposia. Originally the text was developed as the operations manual for the Pacific Region Junior Science and Humanities Symposium (PJSHS). It contains information necessary to…

Discussed are the procedures and results involved in this activity. Student results in undergraduate laboratories indicate high quality results and relative ease of the analysis. (CW)

The National Science Teachers Association (NSTA) has assembled this collection of reprints to assist teachers in organizing a science fair, working with students and establishing equitable judging procedures. The NSTA position statement on science fairs is included. The 19 reprints in this volume are geared toward secondary school students and are…

Described is a base-friction modeling technique for studying the development of collapse structures in jointed rocks. A moving belt beneath weak material is designed to simulate gravity. A description is given of the model frame construction. (Author/SA)

Presented are the procedures and a discussion of the results for an experiment in which students select unknown carboxylic acids, determine their melting points, and investigate their solubility behavior in water and ethanol. A table of selected carboxylic acids is included. (CW)

Describes the state-of-the-art in computer interfacing in the biology laboratory. Discusses hardware and software. Enumerates the educational benefits from instrumentation such as cost effectiveness and increased student opportunity and motivation. Includes 14 references. (CW)

An inexpensive apparatus for demonstrating low temperature mineral synthesis in an undergraduate geology laboratory is described. (Author/SA)

Recommendations are given for obtaining high quality preparations of chromosomes with relatively little equipment using an improved Feulgen-squash technique. (Authors/SA)
