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)

Although much contemporary thinking leads to the expectation that communication technology, such as video streaming, enhances educational performance on the average, a dearth of strong evidence consistent or inconsistent with this claim precludes a thoughtful evaluation of it. A series of experiments designed to examine this proposition…

Imagine a science activity that excites native English speakers and English learners alike while simultaneously teaching students about tools used in science experiments, increasing science vocabulary, and improving students' skills in recording information. Inventorying science kits or materials from science units with students does just that…

In this article, the authors present a classroom experiment that was developed to introduce middle school learners to the carbon cycle. The experiment deals with transfer of CO[subscript 2] between liquid reservoirs and the effect CO[subscript 2] has on algae growth. It allows students to observe the influence of the carbon cycle on algae growth,…
