Provides a model that maps out five stages of relating library and scientific research: (1) establish an interest; (2) narrow a topic; (3) clarify the variables; (4) refine the procedures; and (5) interpret the unexpected. Provides a student questionnaire for selecting a topic and a format for general note taking. (MDH)

Presents five hands-on activities that allow students to detect, measure, reduce, and eliminate moisture. Students make a humidity detector and a hygrometer, examine the effects of moisture on different substances, calculate the percent of water in a given food, and examine the absorption potential of different desiccants. (MDH)

Presents a model of a generic atom that is used to represent the movement of electrons from lower to higher levels and vice-versa due to excitation and de-excitation of the atom. As the process of de-excitation takes place, photons represented by colored ping-pong balls are emitted, indicating the emission of light. (MDH)

Presents the transcript of an interview with the director of the Environmental Futures Center in Moscow to identify current environmental issues that will influence the development of international curriculum resource materials for environmental education. (MDH)

Describes the use of a "Rube Goldberg machine contest" to help students learn physics. (PR)

Describes career opportunities in Clinical Laboratory Science formerly know as Medical Technology. Explains classroom strategies for brining these careers to the attention of students. (PR)

Describes a Principles of Technology course as an innovative approach to teaching physics that does away will the hype and stigma that frightens off many potential students. (PR)

Describes science experiments with the enzyme lactose, which is available commercially as Lactaid and Dairy Ease. Experiments show how the rate of reaction of lactose converted to glucose and galactose is influenced by temperature, pH, and substrate concentration. (PR)

Presents student survey results (n=708) of misconceptions held regarding the atmosphere. Results indicated a basic lack of understanding concerning atmospheric processes and phenomena. Although misconceptions generally decreased with increasing education, some seemed to be firmly rooted. (PR)

Presents a study of four different teaching strategies dealing with comparing lower-level questions with higher-level questions and comparing feedback correctives with no feedback correctives. The lowest levels of achievement were in the class with low-level questions and no feedback correctives. (PR)

Describes a laboratory activity "Observing Reactions in Solution." The activity can be used either as a laboratory or as a performance assessment for a high school chemistry class. (PR)

This activity uses ice crystals to introduce middle school and high school students to the collection, preparation, examination, and manipulation of scientific data. (PR)

An activity that can be used to teach plant nutrition and the use of hydroponics is presented. Materials and procedures are discussed. Possible topics for science projects are suggested. (CW)

Described is a series of workshops designed to familiarize teachers with the social and legal background, principles of humane care, ethical considerations, and philosophies that influence animal use in the classroom. Discussed are the value of dissection, alternatives to dissection, and student reactions to dissection. (CW)

The use of living animals in the classroom is discussed. A checklist of ideas to remember when considering housing animals in the classroom is provided. (CW)
