Laboratory experiments are presented in these first three manuals of a six-volume series for use at the 12- to 16-year-old, or British CSE, level. On the subject of food tests, 17 exercises are prepared in connection with Biuret reactions, starch and emulsion tests, Millon's and Benedict's reagents, reagent sensitivity, and calorific values and…

A MANUAL WAS PRODUCED CONTAINING LABORATORY PROCEDURES FOR A ONE-SEMESTER COURSE IN ELEMENTARY QUANTITATIVE CHEMISTRY ON A COLLEGE FRESHMAN LEVEL. MATERIALS AND TOPICS WERE EXAMINED AND CHOSEN AS TO DESIRABILITY, PRACTICALITY, AND EDUCATIONAL VALUE. OPTIONAL EXPERIMENTS WERE ALSO INCLUDED. THE LABORATORY PROCEDURES WERE TESTED ON SOPHOMORES AND ON…

Outlines an experimental procedure in which an iodine radioisotope is used to determine molar combining ratios of lead and silver with the iodine. Tables and graphs show the definitive results that should be attainable. (CP)

Describes a laboratory experiment in which the students prepare an antichap lipstick from basic ingredients and demonstrate solubility relationships between these ingredients and water. (MLH)

The pedagogy and an extensive listing of topics suitable for large scale demonstrations are provided. (CP)

Describes two experimental procedures and the reactions suitable for teaching the principle that catalysts do not affect the position of equilibrium. (GS)

Describes an activity which incorporates topographic map interpretation, soils analysis, hydrogeology, and local geology in a five-week series of exercises for an introductory college earth science class. (CP)

Provides an account of the way in which one small university has coped with limited funds and a small staff to provide laboratory activities for freshman physics courses. (CP)

Explains an error analysis procedure using the computer which requires no previous student experience with the computer. (CP)

Reported here is a convenient alternative for determining the enantiomeric purity of student resolved alpha-phenylethyl amine using a chiral lanthanide shift reagent. (BB)

This experiment graphically demonstrates a change in the sign of the P-C-H coupling constant between trivalent phosphorus and tetravalent phosphorus. (BB)

This reaction can form the basis of a laboratory experiment for students who have mastered basic spectroscopy. The structure of the product can be assigned from four reasonable possibilities on the basis of the nmr spectrum. (BB)

Describes a demonstration for measurement of biophysical signals produced by the human body. The signals, after amplification, could provide acoustical feedback through a voltage-controlled oscillator (VCO), or they could be seen either with an oscilloscope or a high speed chart recorder. (GA)

The Japanese morning glory, a short-day plant, is an excellent specimen for studying photoperiodism. This article gives ideas for investigations including the effects of hormones, light quality, and temperature. Preparation of the seed is also discussed. (BB)

Describes an exercise which familiarizes students with organic chemistry terms and introduces preferential degradation reactions. (CP)
