This male-specific study examined the development of integrated process skill in the context of open-inquiry laboratory sessions. Findings from this qualitative study indicate that male students develop higher-order process skills through nontraditional laboratory experiences that provided the students with freedom to perform experiments of…

Recounts an anecdote about a teacher's science anxiety resulting from the mysterious results of a plant growth experiment. Students found that bean plants grew taller in a dark closet because of etiolation. Points out that teachers need to deal with experimental results objectively and resist looking for "right" answers. (MDH)

Presents a hands-on lesson that can integrate the use of makeup with studies of the history of Halloween; the history and practices of the theater; Native American or African tribes and their use of paint, makeup, and masks; and the history, skills, and makeup of clowns. (MDH)

Activities involving concave rubber disks are utilized to illustrate the scientific principles of kinetic and potential energy. Provides teacher instructions and questions related to the activity. (MDH)

Provides instructional techniques, using samples from evergreen trees, to explain to school children the concept of adaptation. The techniques help children develop skills in observation, classification, communication, inferring, and predicting. A teacher's reproducible is included. (GLR)

An activity that introduces the concept of chaos to students is presented. Smoke rising from burning incense is used to represent changes in atmospheric flow. The lab, involving fluid dynamics, avoids mathematical models to highlight deterministic chaos within nature itself. Reproducible pages are provided. (KR)

The important role of the digital computer in education is outlined. The existing Indian situation and needs and the scope of the Computer Literacy And Studies in Schools (CLASS) program are briefly discussed. (Author/KR)

A way for students to refresh and use their knowledge in both mathematics and physics is presented. By the study of the properties of the "Runge-Lenz" vector the subjects of algebra, analytical geometry, calculus, classical mechanics, differential equations, matrices, quantum mechanics, trigonometry, and vector analysis can be reviewed. (KR)

The impact of oil spills and oil fires in the Persian Gulf is discussed. Activities to be done in the classroom that simulate oil spills are presented. Sample discussion questions and direction for the activities are included. (KR)

Described is a voluntary museum program where instructors teach science, math, and technology through art. Activities that can be used as "hooks" to get students interested in the program are provided. Topics include privacy and personal space, imaginary worlds, toys, behind the scenes, fads, friendly materials, humor, and the imagination. (KR)

Presented is a method for demonstrating the use of various fractionating columns to resolve mixtures into individual components and to correlate the resolving powers of column packings to their "hold-up" volumes. Fractions were analyzed using refractive indices. (KR)

Presents a reproducible page for students dealing with the following topics: plate tectonics, magma, crust, and earthquakes. Provides a plate tectonics activity that uses cardboard and clay. (PR)

Discusses how to build an inexpensive Young's modulus apparatus and also a lens with an adjustable focal length. Describes the demonstration of moving a peeled, hard-boiled egg in and out of a flask whose neck is slightly smaller than the egg. (MVL)

Presents two methods to teach the phases of the Moon: (1) students use a Styrofoam ball (Moon), light bulb (Sun), and one's own head (Earth) to model the Earth-Moon-Sun system; (2) students use their hands to represent the location of the Sun, Earth, and Moon during a teacher controlled "Moon Dance." (MVL)

Describes an experiment where students test the furcula or wishbone of a bird for its springlike properties. (PR)
