Outlines the importance of teaching the methods of science. Describes ways in which teachers can incorporate lessons about scientific methodology into any existing introductory science course. (JRH)

Describes a classroom exercise that uses a letter from Max Delbruck to George Beadle to stimulate interest in the mechanics of a nonoverlapping comma-free code. Enables students to participate in the rich history of molecular biology and illustrates to them that scientists and science can be fun. (JRH)

Describes an activity by which college students can evaluate various urban environments through a series of responses to polar adjective pairs. This activity clarifies how earth science students feel about the environment, and it also teaches them contour mapping. (HM)

Compared are two approaches to exam writing in which the narrative approach is described as a novel, creative, and integrated learning opportunity. In this approach, a single system is chosen in which questions are asked that challenge the student to perceive interrelationships between principles and details previously learned. (CS)

Describes a laboratory activity which can be done with equipment normally available for introductory college courses. It measures the ratio of the radioactivity per unit mass of a unicellular alga to the radioactivity per unit mass of the medium in which it grows. (HM)

Describes an experiment to characterize the enzyme polyphenol oxidase. Includes Purpose, Reagents and Equipment, Procedure, Extraction, Treatment of Data, and Discussion. (MA)

Describes the use of student-made photomicrographs as a source of student motivation and as a means for review of laboratory exercises in an introductory microbiology course. Includes an evaluation of this teaching method. (Author/MA)

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)

Describes some of the instructional methods tried, the problems encountered, and the philosophies involved concerning individualized instruction in a community college. The two semester introductory biology course emphasizes the open laboratroy concept, with individualized instructional modules prepared for laboratory experiments. (HM)

Describes a simple conductivity apparatus for the determination of ionization and solubility product constants of various substances. The uses of the apparatus in determining the ionization constant of a weak monoprotic acid and in measuring the rate of diffusion of ions through a membrane are also presented. (HM)

Presents a detailed discussion of the "Drinking Duck" toy and its use to illustrate scientific and technical issues in thermodynamics. Numerous illustrations and equations are included. (MA)

Describes how the art of Maurits Escher can be used in physical science and general chemistry classes. A film depicting Escher at work in creating a woodcut and a set of slides are shown to college students. The students are encouraged to observe and record what they see. (HM)

Presents a detailed outline/guide for preparing well-organized grant requests and proposals. (SL)

Describes a series of demonstrations and/or group activities used in a science methods course for prospective elementary school teachers. The topics include center of gravity, behavior of fluids; electricity and magnetism, the motion of objects, chemical reactions, and sound. (GS)

Describes an experimental biochemistry course designed to teach basic biochemical techniques using an unstudied enzyme as the experimental material. Explains the schedule of experiments designed for the course and lists the sources used. (GS)
