Describes an experiment, easily repeated in the classroom, designed to determine whether members of the species Drosophila melanogaster show selective preference in choice of mates. (PEB)

A number of activities are described by which a class can collect biological data about the students in the class. Brief instructions are given. (RH)

This second report from the Analytical Chemistry Subcommittee presents ideas for using real-life samples for student analysis and for introducing the topic of developing procedures for analysis. (DT)

Describes an experiment designed to familiarize students with the operation of a precision spectrophotometer, the effects of changes in operating variables, and the characteristics of such components as sources and detectors. (SLH)

Describes four experiments designed to introduce students to the methodology associated with the construction, evaluation, and use of ion-selective electrodes. (SLH)

Describes a method for the accurate determination of partial specific volume of a protein. Method is simple enough to include in the undergraduate physical chemistry laboratory but requires patience and careful handling which provide good training in laboratory techniques. (SLH)

Describes an interesting, inexpensive, and highly motivating experiment to study uniform and accelerated motion by measuring the position of a car as it crashes into a rigid wall. Data are obtained from a sequence of pictures made by a high speed camera. (Author/SLH)

A required course for graduate teaching assistants on improving the quality of instruction in the undergraduate laboratories is described. As a principal feature of the course, the graduate students improved existing laboratory experiments or developed new ones. Both self-evaluation and evaluation by faculty members were applied to the final…

Skill learning was studied in 247 elementary and high school students, using a pursuit rotor. Data were analyzed by repeated-measures ANOVA. (ST)

Presents some materials for use in demonstration and experimentation of corrosion processes, including corrosion stimulation and inhibition. Indicates that basic concepts of electrochemistry, crystal structure, and kinetics can be extended to practical chemistry through corrosion explanation. (CC)

Presents the results of educational experiments aimed at incorporating APL programming techniques in an undergraduate physical-analytical laboratory course. Included are a list of first year experiments and some examples of operations. (CC)
