An experiment is described which provides a simple example of the application of the Wittig reaction to the synthesis of unsaturated compounds. The experiment was designed with British HNC chemistry students in mind, but it is also suitable as a project-type exercise for final year GCE A-level students. (Author/BB)

Gives an explanation to the process of charging the conventional leaf electroscope, by induction, using a charged insulated rod. (GA)

Explains how to demonstrate the fundamentals of one dimensional kinematics such as Newton's third law of motion, and collision between bodies, using simple materials of marbles, strings, sticky tape, drinking straws, and rubber bands. (GA)

A new, small magnetic susceptibility system is described which can be constructed from commercially available components for less than one hundred dollars for use with a standard laboratory balance. (BB)

A lecture demonstration is presented for comparing titration curves. A plot of pH vs volume of strong base is produced by connecting the external output of a pH meter to a strip recorder. Thus, pH is recorded as a function of time. (BB)

In this experiment, students prepare, isolate, and characterize two geometrical isomers of a metal coordination compound. This experiment provides a good introduction to the techniques of modern coordination chemistry. (BB)

This paper describes an attempt to evaluate the contribution of laboratory experiments on student achievement in an elementary, one-term college chemistry course and suggests some less expensive alternatives. (Author/BB)

Preservice teacher interns learned from direct, first-hand practical experiences rather than just from theoretical ideas, the kinds of feelings a new and stressful situation may elicit. (NQ)

Describes seven computer simulations of laboratory experiments that allow students to direct experiments, make observations, and record data. (MLH)

Describes an experiment that utilizes polarimetry to measure mutarotation of glucose and nmr spectroscopy to identify the structures of reactants and products of biochemical reactions. (MLH)

Describes a new sodium fusion procedure and a new single reagent test for nitrogen and sulfur for use in the analytical lab. (MLH)

Describes an experiment designed to confirm that newly purchased commercial orange juice contains sufficient ascorbic acid to meet government standards, and to establish the rate of aerial oxidation of this ascorbic acid when the juice is stored in a refrigerator. (MLH)

Pharmacy students in Florida may fulfill their internship requirements either by participating in this college-supervised practicum internship program or in the traditional 2080-hour internship program directed by the Florida Board of Pharmacy that requires 1,040 hours be completed before graduation. The practicum provides 400 hours. (LBH)

Describes an exercise that extends the actual determination of the amino acid sequence of a simple dipeptide to the theoretical determination of the complete primary structure of a larger polypeptide. Includes diagrams of display cards and duplicated sheets used in the theoretical portion of the exercise. (CS)

Describes a student experiment in which a pendulum is swung through angles up to 160 degrees by suspending it on a solid rod. Graphical analysis is used for empirically determining parameters. (MLH)
