Suggests that students can develop the ability to do science in an informal environment such as a zoo, aquarium, or museum. Informal environments provide live organisms, specimens and scientific objects that students can explore and study. (CCM)

Explains how "Downy Ball" fabric softener dispensers can be used to demonstrate Newton's First Law in physics class. (WRM)

Introduces the international science education program Global Learning and Observations to Benefit the Environment (GLOBE). The program is based on the active, hands-on involvement of students and data collected using the scientific protocols file on GLOBE's website. (YDS)

Introduces The Traveling Scientist program which can be used as an extension to the science curriculum. Targets 1st and 2nd grade students. (YDS)

Discusses teaching techniques for teaching about rocks, minerals, and the differences between them. Presents a model-building activity that uses plastic building blocks to build crystal and rock models. (YDS)

Presents a science unit in which students design and test a sample of concrete and later redesign it to improve the strength of their sample under compression. (YDS)

Presents hands-on activities to teach about the causes and consequences of strokes. (YDS)

Introduces some of the core concepts of ecological economics and describes sample activities that can be used at various grade levels. Presents a hands-on simulation on manufacturing. (YDS)

Describes a mathematics and science project designed to help students gain some familiarity with constellations and trigonometry by using the TI-83 calculator as a tool. Specific constellations such as the Big Dipper (Plough) and other sets of stars are located using stereographic projection and graphed using scatterplots. (MM)

Molecular modeling by computer is used to display stereochemistry, molecular orbitals, structure of transition states, and progress of reactions. Describes new ideas for teaching 1H NMR spectroscopy using computer modeling. (Contains 12 references.) (ASK)

Describes strategies to introduce students in a first year chemistry course to the gas chromatograph coupled with a mass spectrometer (GC-MS) and provides students with hands-on experiences in its use. (ASK)

Introduces a laboratory science course addressing scientific literacy. Includes three interrelated student projects for the laboratory section of the course. (Contains 27 references.) (YDS)

Reviews two dimensions in which science and technology share fundamental similarities: (a) the production and transformation of representations; and (b) the action-oriented language that describes the two domains. Illustrates what and how students know and learn science during technological design activities. (Contains 66 references.) (Author/YDS)

Presents two components of a piece of experimental equipment, the optical training ground and the electrical panel, which can be used to construct and test different electrical circuits and study laws of electricity, experimental problem solving, and basic light phenomena. (YDS)

Outlines what is currently known about Australian dinosaurs, where dinosaur fossils are found, and a field trip to look for dinosaurs. (ASK)
