Explains that triglycerides consist of a mixture of different compounds, depending on the total number of fatty acid constituents. Details the method and instrumentation necessary for students to analyze a vegetable oil for its triglyceride content. Describes sample results. (CW)

This book, addressed to students for their independent use as well as to teachers as a supplement to the standard texts, contains nearly 100 practical science experiments that cover a wide range of subjects at different grade and ability levels. It is designed to involve students in active scientific experimentation, demonstrations, and projects…

This Chemistry-Materials Laboratory Project Book, assembled through a survey of science instructors in vocational-technical schools in Connecticut, is intended to meet a variety of needs. It can serve as an idea book, with the instructor taking from it as needed and adding or substituting material related to class interests; as a guide book for…

This textbook aims to fill the need of an Introduction to Chemical Analysis, solely designed for use in the laboratory. This text presents simple rules for conducting chemical analyses to help students arrive at the most reliable results. This third edition has increased the examples for practice in quantitative and especially volumetric analysis.…

Describes a physical chemistry laboratory experiment that illustrates the concepts of inductive and resonance effects by the calorimetric determination of the heats of protonation of pyridine, 2-chloropyridine, and 3-chloropyridine. (CS)

Investigations in Natural Science is a program in secondary school biology, chemistry, and physics based upon the description of science as a quest for knowledge, not the knowledge itself. This student manual contains the 19 chemistry investigations. These investigations focus on concepts related to: interactions with water; salt and calcium;…

Describes an experiment that emphasizes the discrete nature of the different oxidation states of vanadium by the separation of ammonium metavanadate into all four species by ion exchange chromatography. (CS)

This document contains a collection of low cost labs and activities. The activities are organized into the following units: Chemistry; Microbiology; DNA to Chromosomes; Genetics; Evolution; Classification, Protist, and Fungus; Plant; Invertebrate; Human Biology; and Ecology and Miscellaneous. Some of the activities within these units include: (1)…

Describes a first-year chemistry experiment that illustrates the fundamental concepts of a photoinduced reaction. Qualitative and quantitative parts of the photoreduction of potassium ferrioxalate are detailed. (CS)

Describes an advanced level experiment in which a transition metal cluster compound, cyclopentadienylcarbonyliron tetramer, is synthesized and characterized spectroscopically. Its redox properties are then explored through cyclic voltammetry. (CS)

The purposes of water treatment in a marine steam power plant are to prevent damage to boilers, steam-operated equipment, and steam and condensate lives, and to keep all equipment operating at the highest level of efficiency. This laboratory exercise is designed to provide students with experiences in making accurate boiler water tests and to…

Describes an experiment which illustrates the general aspects of intermolecular energy transfer between triplet states in rigid solutions of organic compounds solved in an ethanol-ether mixture. Measurements of quenching and energy transfer processes are made using the chemicals of benzophenone and naphthalene. (CS)

The goal of this mini-curriculum is for students to examine, discover, and compare the physical and chemical properties of soil. Seven units are designed to be presented as a lecture and to allow 30 to 40 students to perform every procedure, each testing their own soil sample. Games are provided in each section to reinforce the concepts presented…

Background information, lists of materials needed, and procedures are provided for 12 electrochemistry experiments. The experiments involve investigating: (1) a simple electrical circuit; (2) how a doorbell works; (3) how a two-way switch works; (4) conductors and insulators; (5) controlling current with a pencil; (6) what an electrolyte is; (7)…

Provides a list of the reactions commonly used for introductory kinetics studies. These reactions illustrate the kinetics concepts of rate law, rate constant, and reaction order. Describes a kinetic study of the hydrolysis of 3-bromo-3-phenylpropanoic acid which offers many educational advantages. (CS)
