Presents an experiment in which students can verify a number of basic ideas about electrical circuits and resistors. (CCM)

Compares micro-rockets to commercial models and water rockets. Finds that micro-rockets are more advantageous because they are constructed with inexpensive and readily available materials and can be safely launched indoors. (CCM)

Describes a scavenger-hunt activity in which students were invited to find certain chemistry-related items and chemical information. (CCM)

Describes an adaptation of the chemistry of lightsticks to use the calculator-based laboratory (CBL) interface, a TI-82/83 graphing calculator, and an easily manufactured wooden block as the support system. (CCM)

Presents activities for acquainting children with the properties of air and the problem of air pollution. (Author/CCM)

Finds that many restoration projects have attempted to replace the native species, but project planners often have an imperfect understanding of the plant communities they are trying to re-create. Argues that when students join these projects, they may receive an inaccurate impression of local ecosystems. (Author/CCM)

Discusses vandalism to schoolyard habitat site areas. Finds that instances of vandalism are few and the threat of vandalism can be kept to a minimum while students, teachers, and community members enjoy a hands-on, outdoor learning opportunity. (Author/CCM)

Provides a range of practical suggestions and experiential advice for organizing a science exposition. Presents three case studies of school expos. (CCM)

Presents a science activity on modeling a bridge to teach about the forces of tension versus compression. The activity is designed for middle school students. (YDS)

Features astronomy activities that teach the value and limitations of inferring. (YDS)

Introduces a high school science curriculum that embodies inquiry-based genetics, evolution, and astronomy. Presents two astronomy units of scientific modeling. The first activity involves a black box to explain a hidden mechanism's effect on the outflow of water. The second activity involves the development of celestial motion models to explain…

Examines motivational methods among undergraduate chemistry students and identifies differences between methods of persuading students to prepare for laboratories. Methods include quizzes, scheduled presentations, unscheduled presentations, and a control method. (YDS)

Presents a project for modeling cellular ultrastructure for 14-17 year old students that helps to develop concepts of measurement and scaling in addition to supporting student understanding of cell biology. (Author/YDS)

Explores different solubility processes and related issues, including the second law of thermodynamics and ideal mixtures, real liquids, intermolecular forces, and solids in liquids or gases in liquids. (Contains 22 references.) (ASK)

Surface tension is a fundamental obstacle in the spontaneous formation of bubbles, droplets, and crystal nuclei in liquids. Describes a simple overhead projector demonstration that illustrates the power of surface tension that can prevent so many industrial processes. (ASK)
