Describes a general chemistry level kinetics experiment requiring three 3-hour laboratory periods. Data analyses can be accomplished with graphical techniques or a non-linear least squares computer program. (MLH)

Describes an experiment in which general and physical chemistry students can determine the heat of vaporization of a volatile substance from experimental laboratory data using timesharing techniques. (MLH)

A reaction kinetics experiment for the chemical engineering undergraduate laboratory course was developed in which in-situ Fourier Transfer Infrared spectroscopy was used to measure reactant and product concentrations. The kinetics of the hydrolysis of acetic anhydride was determined by experiments carried out in a batch reactor. The results…

Describes a number of activities designed to assist student understanding of the phenomenon of light bending when it passes from one meduim to another. (JR)

Describes the sturcture and asexual reproduction of the fungus Pilobolus and outlines a number of experiments with this organism that are suitable for secondary school biology students. (JR)

This document provides abstracts of 116 laboratory experiments/demonstrations currently being utilized in all areas of engineering education at 52 universities across the United States. (SL)

Presented is a descriptive account of Alessandro Volta's first notable success in 1775, the invention of a unique method of generating electricity. Luigi Galvani's announcement of his theory of "animal electricity" in 1972 is integrated into this interpretation of Volta's discoveries with electricity. Five experiments are described: (1)…

Seven experiments and 40 activities are presented in this handbook. The experiments are related to Young's experiment, electric forces, forces on currents, electron-beam tubes, and wave modulation and communication. The activities are primarily concerned with aspects of scattered and polarized light, colors, image formation, lenses, cameras,…

Five experiments and 19 activities are presented in this Unit 5 handbook. The experiments are related to electrolysis, charge-to-mass ratio, elementary charge determination, photoelectric effects, and spectroscopic analyses. The activities are concerned with Dalton's theory, water electrolysis, periodic tables, single-electron plating, cloud…

Five experiments and nine activities are presented in this Unit 6 handbook. The experiments are related to random events, ranges of alpha and beta particles, half-lives, and radioactive tracers. The activities are concerned with the energy measurement in beta radiation, demonstration with sugar cubes, ionization by radioactivity, magnetic…

Presents four simple laboratory procedures for: preparation of organometallic compounds, a realistic qualitative organic analysis project, a computer program to plot potentiometric titration curves, and preparation of stereoscopic transparencies. (SL)

Describes an organic chemistry laboratory exercise which uses thermochromic compounds to study the thermodynamic effect of temperature on chemical equilbrium. (SL)

Describes a series of polarography experiments using commercially available pulse polarography instruments. (SL)

A laboratory experiment is described which illustrates such concepts as resonance, inductive, steric, and solvation effects in a beginning organic chemistry course. This experiment is designed to encourage students to predict results and interpret their findings. (MR)

Describes a demonstration experiment illustrating rotation of grains process of metamorphic rock formation utilizing clear gelatin blocks. (SL)
