The trebuchet has quickly become a favorite project for physics and engineering teachers seeking to provide students with a simple, but spectacular, hands-on design project that can be applied to the study of projectile motion, rotational motion, and the law of conservation of energy. While there have been free trebuchet simulators and range…

Neo magnets are neodymium magnet beads that have been marketed as a desktop toy. We proposed using neo magnets as an alternative building block to traditional ball-and-stick models to construct carbon allotropes, such as fullerene and various nanocone structures. Due to the lack of predetermined physical connections, the versatility of carbon…

This paper presents a simplified approach for the application of material efficiency metrics to linear and convergent synthesis plans encountered in organic synthesis courses. Computations are facilitated and automated using intuitively designed Microsoft Excel spreadsheets without invoking abstract mathematical formulas. The merits of this…

Proposes the V-Scope as a teaching aid to measure, analyze, and display three-dimensional multibody motion. Describes experiment setup considerations, how measurements are calculated, graphic representation capabilities, and modes of operation of this microcomputer-based system. (MDH)

Discusses several ways of teaching about constellations. Includes background and historical information, suggestions on visiting a planetarium, and a bibliography for sources of constellation stories, computer courseware, and constellation slides. Suggests ways of having students produce their own constellation slides. (TW)

Discusses some of the variables teachers must consider when using computer software in the science classroom. Describes eight commercially available computer programs that are designed to teach problem solving in science. Includes the producer's address, the grade level for which the program was written, and a critique. (TW)
