Describes two experiments, one involving the electrolysis of potassium iodide and the other involving a diffusion process in solid copper. (GS)

Presents an approach to the understanding of gas laws using such common phenomena as insect fogging, sea breezes, and hot air balloons. (GS)

Presents the findings of a survey used to evaluate the effectiveness of a resource center using the following categories: use versus nonuse, frequency of use, purpose of visit, and satisfaction. (GS)

Describes the basic routine of the course and the titles of the 49 tape-slide lectures. Presents the advantages and disadvantages of the tape-slide format. (GS)

Describes the use of videotapes to eliminate or shorten in-lab instruction and prevent interruption of a laboratory session with additional or forgotten instruction. Lists equipment needed for videotape programs and for a thirteen unit audio-visual laboratory. (GS)

Describes the use of laboratory experiments termed hands-on demonstrations that are designed to reinforce the concepts covered in lecture with emphasis on maximizing the sense content (sight, smell, hearing) to improve retention by the student. (GS)

Describes a program built on the philosophy that laboratory exercises were to be exclusively reserved for those concepts which could not be taught more effectively by other pedagogical techniques. Presents faculty and student criticisms of the program. (GS)

Traces the historical development of the university instructional laboratory. Describes the basic components of a problem-oriented laboratory program and identifies four forces that may dictate instructional change in the future. (GS)

Describes an experiment in which possible products of a series of reactions are tabulated together with properties which may be useful in identifying each substance. The student deduces the products and writes a balanced chemical equation for the reaction. (GS)

Describes an experiment wherein the student can demonstrate the existence of all the thiocyanato chromium complexes, estimate the stepwise formation constants, demonstrate the robustness of chromium III complexes, and show the principles of paper electrophoresis. (GS)

Describes an experiment that will acquaint the student with the ion-exchange model, yield data which fit nicely to a computer type analysis, introduce the preparation of electrodes, provide a unique experience with elevated temperatures and ionic solvents, and provide experience in electrometric measurements. (GS)

Describes an open-ended experiment involving a bioinorganic system that provides the student a direct link between thermodynamics and kinetics. It utilizes a rapid reaction technique and requires one to clearly understand the relationship of experimental observable (absorbance) to a mechanism. (GS)

Describes an experiment that illustrates the use of the preparative ultracentrifuge in isolating and purifying bacterial ribosomes, determines the sedimentation coefficients of the ribonucleoprotein particles, and demonstrates the subunit structure of the 70-S ribosome and the role of the magnesium ion in the association of subunits.
