Described are two reviews of a computer software package: "The Periodic Table Stack," a Hypercard stack that operates on a database of information about the properties and reactions of the elements and designed to help users of Macintosh computers access data found on "KC? Discoverer." Discussed are features of the program and…

Described is a program which encouraged parents to become involved with their children in a science program at home. Discussed are the activities and organization of the program. A list of resources is provided. (CW)

Described is a capstone experiment which can be used to improve student skills and to illustrate for students the strong connections between chemistry and biology. Procedures and explanations for the three parts of this activity are included. Ten follow-up questions are provided. (CW)

Pollination vectors of a variety of types are described including beetles, bees, flies, moths, birds, bats, and the wind. Some of the adaptations of plants designed to help facilitate pollination are discussed. Strategies for incorporating this information into a lesson plan are suggested. (CW)

Background information, procedures, and suggestions for bird feeder studies easily conducted in high school or middle school settings are provided. Data collection and analysis are discussed. Examples of charts produced by these activities are given. (CW)

Described are some of the difficulties presented in these reactions by competing equilibria that are usually ignored. Situations involving acid-base equilibria, solubility product calculations, the use of ammonia as a complexing agent, and semiquantitative comparisons of solubility product values are discussed. (CW)

Described is a five-week introductory inorganic laboratory course for first-year undergraduate students. Included are details of three preparations and three analyses conducted by the students in the course. (CW)

Reviews research on the purpose and effectiveness of laboratory activities. Discusses epistemology, problem solving, cooperative learning, student involvement, assessment, and teachers as researchers. (YP)

Presented is an approach to introducing upper division, undergraduate geology students to nonparametric statistics and their application to geologic data. Discussed are the use of the Mann-Whitney U and the Kolmogorov-Smirnov tests and a class assignment which illustrates their use. (CW)

Describes apparatus for Doppler demonstrations. Provides several pictures of the apparatus and ways it could be used. (YP)

Presented is an astronomy activity in which students use an apparatus to illustrate the various positions and movements of the sun, earth, planets, stars, and constellations. A test of the heliocentric theory of the solar system is included. (CW)

Suggested are ways that problem solving can be integrated into existing college courses. Modification of assignments, reduction of class examples, developing the structure of knowledge, finding time to teach process skills, and developing student awareness are discussed. A self-assessment form for students is included. (CW)

Provided are 26 ideas to help children explore the effects of mountains on the weather. Weather conditions in Nepal and Colorado are considered separately. Nine additional sources of information are listed. (CW)

Presented are gravimetric and volumetric procedures which may be used by students to measure the zinc coating on steel. Listed are materials, methods, calculations, and discussion questions. (CW)

Introduces a computer solution of the oscillation of a mass suspended by a spring in a viscous liquid. Describes the equations of motion, spreadsheet solution, copying the formulas, plotting the results, and extending the applications. Presents spreadsheet and physics formulas for the step-by-step solution and spreadsheet solution. (YP)
