This training manual, intended for chemists and technicians with little or no experience in chemical procedures required to monitor drinking water, covers analytical methods for inorganic and organic chemical contaminants listed in the interim primary drinking water regulations. Topics include methods for heavy metals, nitrate, and organic…

This instructor's manual presents information for a training course in analytical methods for inorganic and organic chemical contaminants listed in the interim primary drinking water regulations. Topics focus on: (1) pre-course activities, including course logistics, equipment, and facilities; (2) sample agendas; (3) lesson plans for specific…

This document contains lab activities, problem sets, and a tape script to be accompanied by a slide show. The minicourse covers the following topics of general chemistry: kinetic-molecular theory, the Bohr atom, acids, bases, and salts, the periodic table, bonding, chemical equations, the metric system, computation of density, mass, and volume,…

This learner's guide on indicator organisms is derived from a water monitoring curriculum developed at Ulster County Community College. There are 37 modules in this guide; each is introduced with a statement of purpose and then broken down into units of instruction. These units contain an objective, learning conditions, and a performance level.…

THIS INVESTIGATION WAS DESIGNED TO COMPARE CHANGE IN CRITICAL THINKING IN GROUPS OF STUDENTS STUDYING HIGH SCHOOL BIOLOGY IN LABORATORY-CENTERED CLASSES AND IN LECTURE-DEMONSTRATION-CENTERED CLASSES. TWENTY BIOLOGY CLASSES WERE RANDOMLY SELECTED FROM THE FOUR SENIOR HIGH SCHOOLS IN THE SALT LAKE CITY SCHOOL DISTRICT. TEN CLASSES WERE RANDOMLY…

Presented is advice on how to set up and maintain a saltwater aquarium, and a discussion on everything from algae growth to constructing an underground filter to hatch brine shrimp. Information on which tropical and temperate animals are appropriate for marine aquaria and how to collect them is also included. (Author/SB)

Presented are basic concepts of chemistry necessary for operators who manage drinking water treatment plants and wastewater facilities. It includes discussions of chemical terms and concepts, laboratory procedures for basic analyses of interest to operators, and discussions of appropriate chemical calculations. Exercises are included and answer…

This module is intended to provide an understanding of the principles related to heat transfer. The objectives are designed to enable the learner to select and install a device for measuring the temperature of a power transistor, determine power ratings, measure the transient response for a power level and its final equilibrium temperature. Other…

A brief summary of the effects of light on plant germination, growth and development, including photoperiodism and pigment formation, introduces 18 experiments and demonstrations which illustrate aspects of these effects. Detailed procedures for each exercise are given, the expected results outlined, and possible sources of difficulty discussed.…

This manual contains a suggested Oceanographic Field Course designed as a supplement to an eighth grade science program. The three principle objectives of the course are: (1) to stimulate the interest of young students in the marine sciences; (2) to instruct students in the scientific method of field observation and laboratory investigation; and…

Robert M. Gagne, Ralph W. Tyler, and Wilbert J. McKeachie, in independently prepared statements made before a summer institute on effective teaching, emphasized that good learning is active rather than passive; stresses the learning of principles; exploits the advantages in newness: exploration of something new, a new practice, a principle learned…

A total program for the preservice education of secondary school biology teachers is suggested in this document based on a joint committee of the Biological Sciences Curriculum Study and the Commission on Undergraduate Education in the Biological Sciences. Suggestions are made for both the professional education and the biology core components of…

Two articles in this newsletter describe programs related to the use of investigative laboratories in college biology; one reports on student reactions to such laboratories; and two articles describe student directed activities concerned with environmental factors. Comments on the changing role of biology in the 70's, and its implication for…

Trends, from 1960 to 1963, in the teaching of chemistry in secondary schools in Austria, Belgium, Denmark, France, Germany, Greece, Ireland, Italy, Netherlands, Norway, Spain, Switzerland, Turkey, United Kingdom, and the United States of America are outlined in the first part of this report of a 1963 working session on the teaching of school…

The present situation of biology teaching in Australian secondary schools is described in Part 1 of the proceedings of the 1970 conference on "Biological Education in Australian Secondary Schools." The six papers discuss the relationship of biology to other science and non-science subjects, enrollment trends, teacher qualifications, and…
