Describes an inquiry lab that helps students discover the chemical nature of enzymes. (PR)

Describes the transformation of PHY 101-02, an introductory physics course taught at Northern Virginia Community College, Annandale Campus, into a distance learning course by putting the lecture component on video tape and transforming the laboratory component into "at-home" labs. Course requirements may be completed on students' own…

Presents an activity that allows students to observe crawling and swimming behavior in Lumbriculus variegatus, a freshwater oligochaete worm. Contains 12 references. (WRM)

For a two-year period, 32 secondary students gifted in the areas of mathematics and science participated in a curriculum which incorporated higher-level thinking skills and more real-life laboratory experiences into mutually reinforcing mathematics and science lessons. After the program, participants scored higher on mathematics and science…

Describes an experiment that extends Newton's instantaneous-impulse method of orbital analysis to a graphical method of orbit determination. Discusses the experiment's usefulness for teaching both horizontal projectile motion and instantaneous impulse. (WRM)

Describes a survey of the views of students, teachers, advisers, and inspectors on school science at key stages 3 and 4 (11-16 year-olds) in the United Kingdom. Finds a mismatch between the intended purposes of the Science National Curriculum and supporting documentation, and its translation into classroom practice. (Author/WRM)

Describes the haze-monitoring program that was added to the protocols of the Global Learning and Observations to Benefit the Environment (GLOBE) Program. Finds that sun photometry provides a convenient means for allowing students to perform hands-on science while learning about various topics in history, electronics, algebra, statistics, graphing,…

Analyzes the evolution of the French physics curricula and experiments from the beginning of the century to the present. Shows the strong coherence of the aspects of energy presented through teaching content and experiments. (DDR)

Describes absorption spectroscopy experiments that allow students to explore the mechanisms by which sunscreens and sunglasses provide protection from ultraviolet radiation. Exposes students to absorption phenomena in an engaging way. (DDR)

The theory that children's development of strategies-of-science experimentation is a consequence of developments in theory of mind was examined with 72 children in grades one, three, and five. Ability to predict, explain, and affect the reasoning of a doll or cartoon character predicted performance in planning controlled experiments and in…

Describes an ammeter that can be built for less than a dollar with commonly available parts to be used in circuits with 3-volt light bulbs. (WRM)

Describes the development, preparation, and use of a medium that can select against a wide variety of Gram-negative bacteria while still allowing growth and differentiation of a wide range of Gram-positives. (WRM)

Describes a short undergraduate course built entirely around a research trip to an astronomical observatory. (WRM)

Describes a review of research that addresses the effectiveness of simulations in promoting scientific discovery learning and the problems that learners may encounter when using discovery learning. (WRM)

The use of complex instruments for chemical analysis is becoming increasingly important. Unfortunately, because of school budgetary constraints, many students are not exposed to these methods until they reach the college level. When students do have access to sophisticated instruments, they often view them as black boxes, with little or no…
