Describes a role-playing game that can be used by high school teachers to teach ecology. The procedures of the game are accompanied by pointers for teachers. (SA)

Describes the phenomenological and microscopic aspects of solid-state diffusion in an electric field and presents a Monte Carlo method which is used to stimulate an atomistic model of diffusion in an electric field. The Nernst-Einstein relation is also discussed. (HM)

Describes an experiment in which acetaminophen is converted into phenacetin, that has been used at Shepherd College in an introductory chemistry course for nurses and in the organic chemistry laboratory. (BT)

A discussion is given of the ways in which thermal conductivity, velocity, and viscosity of sound propagation of gases can be measured by freshmen college students. (Author/SA)

The use of microcomputers in the undergraduate chemistry laboratory is presented. Examples are included which can be implemented in the PET 2001. (SA)

Described is a one-week summer chemistry workshop held at Lebanon Valley College, Annville, Pennsylvania, for secondary school students. Experiments and evaluation results of the workshops are provided. (HM)

Describes the details of constructing, and use of, a solar collector. Uses a black liquid to absorb the energy, the thermosyphon effect to drive the liquid through the collector, and a floodlamp as a surrogate sun. (GA)

Describes a spot test experiment, designed for use in the undergraduate laboratory, that has been adopted to follow the progress of coupling reactions. (BT)

Describes a competitive oil-play game for petroleum geology students. It is accompanied by a computer program written in interactive Fortran. The program, however, is not essential, but useful for adding more interest. (SA)

Presents a description for maintaining adult forms of molluscs and protochordates in order to obtain gametes for laboratory studies of animal development. The methods also include those for culturing embryonic larvae forms in vitro. (Author/SA)

Describes three college lab exercises which can be used to demonstrate the elements and characteristics of continuous flow injection analysis. (HM)

Through the use of science-reading kits, one teacher develops practical application of children's reading skills. Each child designs and builds appropriate materials for science learning kit on the subject of his/her choice. (SA)

Science learning experiences and activities for primary-aged school children, are suggested. They are intended to contribute to development of spatial conception in students. (SA)

Described is a multidisciplinary group project for undergraduate students in astronomy and physics. The students design and build a simple radiotelescope subject to a number of realistic constraints such as fixed cost, use of a standard communications receiver, and buying of supplementary building materials off the shelf. (BT)

These activities focus on the unifying concept of faster-moving fluids lowering fluid pressure. Students are able to visualize and measure the dynamics of fluid pressure with the hands-on approach of these activities, which helps to develop conceptual understanding. Activities are organized to show many examples of the same concept to reveal…
