Uses a moderately priced digital multimeter that has output and software compatible with personal computers to make a portable, computer-based data-acquisition system. The system can measure voltage, current, frequency, capacitance, transistor hFE, and temperature. Describes field measures of velocity, acceleration, and temperature as function of…

Provides a method of demonstrating triangles on a curved surface to aid the student in seeing that the sum of the angles are either more or less than 180 degrees depending upon which side of the sphere the triangle is placed. (MVL)

Describes the use of NASA Spacelink Computer Information Service for Educators to obtain instructional materials and ideas for classroom demonstrations. Uses the free-fall concept of zero gravity as an example. Provides NASA Spacelink contact information. (JRH)

Describes an activity that involves exploring a model cave made out of a two-person tent as a way to add science process to a thematic unit on bats and spiders. This multifunctional learning center provides students with a variety of hands-on experiences, helps students focus on observable things from nature, and emphasizes process skills. Lists…

Describes a learning-cycle approach to teach a lesson exploring the biotic potential of plants. Discusses the phases of learning: exploration, concept invention, and application. Lists five resources. (JRH)

Presents performance assessments, written by a team of Wisconsin science teachers, designed to see if students know, have practiced, and are able to perform the skills associated with science problem solving. (JRH)

Describes activities for biology teachers that will stimulate discussions on virus structure, cell biology, rhino viruses, and new trends in treating the common cold. Provides opportunity for inquiry and problem solving in exercises that emphasize an understanding of how common cold viruses might pack inside nasal epithelial cells. (14 references)…

Presents the National Science Education Standards as an exceptionally well researched tool intended to assist teachers in curriculum development. Describes an activity that meets the standards and encourages students to work together. (JRH)

Explains how peer scores can be used to constitute one part of students' grades on group projects. Contributions students make to a project are defined in four categories: creativity/ideas contributed, research/data collection, writing/typing/artwork, and organizing/collating. A scoring rubric for these categories is presented. (PR)

Describes the use of the observational checklist as an alternative assessment method. Suggests scoring rubrics should be developed to allow students and teachers to understand what standards are expected. Example scoring rubrics for drawing conclusions, creating motion, and group/cooperation skills are presented. (PR)

Presents an activity in which students make a simulated solar panel to learn about the principles behind energy production using solar panels. Provides information about how solar panels function to produce energy. (MCO)

Describes two library-lab exercises the authors have incorporated into their college chemistry course. The first exercise introduces students to scientific information and familiarizes them with the tools for accessing it. The second provides a framework for evaluating the reliability of that information and addresses the criteria that should be…

Described is a computer software package suitable for teaching and research in the area of multicomponent vapor-liquid equilibrium. This program, which has a complete database, can accomplish phase-equilibrium calculations using various models and graph the results. (KR)

Describes six simple experiments that can enable students to better understand gravity and the role it plays in the universe. Includes discussions of Newton's experiments, weight and mass, center of gravity, center of mass, and the velocity of falling objects. (JJK)
