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)

Presents an experiment in which a programmable calculator is employed as a data generating system for simulated laboratory experiments. The example used as an illustration is a simulated conductimetric titration of an aqueous solution of HC1 with an aqueous solution of NaOH. (Author/EB)

Describes the construction of a calorimeter to be used in an experiment which consists of measuring the rate at which ground level solar radiation raises the temperature of the metal in the calorimeter. (GS)

Explains two approaches for stimulating the intellectual development of the student from the concrete to formal operations level. One method involves experimentation and critique during which the student deduces the principle. The second involves a lecture approach that utilizes the creation of the discrepant event. (GS)

Describes an experiment designed to augment textual materials conducive to the inquiry approach to learning. The experiment is the culminating experience in a series designed to illustrate the fundamental nature of the atom: its quantized energy nature, its electrical nature, and its combining ability. (Author/GS)

Describes an experiment for recording holograms using a minimum of costly apparatus. Includes a description of apparatus and materials, the procedure for recording the hologram, the processing of the hologram, and the reconstruction of the image. (GS)

Describes an undergraduate experiment. Discusses a model for the behavior of bubbles under differing viscosities and pressure gradients and conditions for failure of the model. (GH)

Describes a method for the determination of the velocity of sound using a dual oscilloscope on which is displayed the sinusoidal input into a loudspeaker and the signal picked up by a microphone. (GS)

Presents a flowchart that is used in the elementary qualitative analysis of a single salt. (GS)
