Includes the complete listing for a computer program which draws the best curve to fit calibration data obtained from a set of five standard solutions. (DH)

Describes a simple method for determining self-inductance of non-ferromagnetic rings. Suggests fitting the ring with an auxiliary coil and using a solenoid driven with a known frequency alternating current. Amplitude change and phase shift can be measured and used to calculate inductance. Material list, calculations, and sample results are given.…

Proposes that leaf yeast serve as quick, inexpensive, and effective techniques for monitoring air quality. Outlines procedures and provides suggestions for data analysis. Includes results from sample school groups who employed this technique. (ML)

Background information, list of materials needed, and procedures used are provided for a simple technique for generating mechanically plotted acid-base titration curves. The method is suitable for second-year high school chemistry students. (JN)

A five-week course for fourth- and fifth-grade students (titled "Chemistry for Kids") was developed. Each class session consisted of a brief lecture, a demonstration, and one or more experiments. An outline of concepts fostered, instructional strategies, and procedures used is provided. (JN)

Describes a series of four experiments designed for small group involvement (each requiring 6 days) emphasizing students' scientific methodology. Topics include: feeding behavior; light/temperature effects on reproduction; effect of density on feeding; and altered male/female ratios on male behavior. Each experiment includes introduction, material…

Describes three experiments measuring changes in children's social speech which used the presence or absence of partitions allowing partial visual contact to alter verbal communication contingencies between players. Altered levels of speech and specificity confirm importance of physical environmental factors in regulation of children's play. (MBR)

Describes a laboratory experience for a general biology or physiology course designed to increase awareness and promote principles of exercise prescription. The fitness evaluation methods utilized, use of the microcomputer to manipulate data from diagnostic tests, development of individualized exercise prescriptions by each student, and…

Ferns in culture provide versatile and easily manipulated material for a wide variety of experiments and observations. Information is provided that supplements earlier reports of the vast experimental potential of these cryptogams and outlines laboratory exercises which reveal the regenerative behavior of fern tissue. (JN)

Since 1977, six different classes of Ashland High School (Ohio) biology students have been monitoring a local river for the presence of sewage treatment plant effluent. Several project results, physicochemical parameters, and data on biota collected at two stations are presented. (JN)

Describes an introductory chemistry course for nurses in which students learn basic chemical principles by performing 12 chemical analyses that are routinely conducted on body fluids and listed on a patient's clinical laboratory chart. (MLH)

Whether you're a stream studies novice or a veteran aquatic monitor, "Watershed Dynamics" gives you abundant practical resources to extend your students' investigations into local water quality and land-use issues. This two-part set is ideal for teaching biological and ecological concepts and research techniques. It also shows how the interplay…

Japanese lesson study, in various adapted forms, is becoming increasingly significant in professional development of mathematics teachers in the USA. Our goal in the research reported in this paper was to investigate, in a three-tiered teaching experiment, the cycles of learning of two researchers, six teachers, and the students in three grade 4…

Language teachers with little or no experience in conducting research are guided through the process of deciding what kind of classroom research to undertake, and how to organize and implement it. In question-and-answer format, four types of research are defined and explained separately: action, survey, correlational, and experimental studies. For…

This monograph contains 10 plant pathology experiments that were written to correspond to portions of a biology curriculum. Each experiment is suitable to a biology topic and designed to encourage exploration of those biological concepts being taught. Experiments include: (1) The Symptoms and Signs of Disease; (2) Koch's Postulates; (3)…
