This experiment demonstrates the reduction of inorganic sulfate to sulfide in the pore water of estuarine muds. Procedures involve the incubation of mud samples for varying amounts of time followed by gravimetric determination. (Author/SA)

Uses inexpensive equipment to demonstrate, through factorial design, an interaction between genetics and environment. Provides instructions for introducing and conducting the experiment, reporting that significant results are usually obtained. Notes the exercise is appropriate for experimental psychology, developmental psychology, behavior…

Provides real life assignments that can be used to help students apply chemistry laboratory techniques to solve environmental hazardous waste problems. Numerous diagrams are provided to aid in describing the experiments performed. (ZWH)

Urges the use of the immediate environment of the school to serve as a focus and a medium to help plan activities and experiments in the different subject areas of science, and in the area of environment. (GA)

A major contributor to our understanding of the adaptation of all organisms to the physical environment is physiological ecology. Described here is an inexpensive, reliable and simple experiment to aid in helping students to understand better the acclimation process. (ZWH)

This teacher's guide on acid rain is divided into three study areas to explain: (1) what causes acid rain; (2) what problems acid rain has created; and (3) what teachers and students can do to help combat acid rain. Instructions for activities within the study areas include suggested grade levels, objectives, materials needed, and directions for…

Describes a two-quarter chemistry course designed to enable civil engineers to perform water analysis studies. (PB)
