Chemists have always designed and deployed cross-disciplinary approaches that interface chemistry with other disciplines to proffer solutions to many human problems. We designed a laboratory experiment that implements chemistry concepts in a biological model to prime undergraduate students to appreciate interdisciplinarity as an approach to…

This research aims to examine the effect of integrating arts in a laboratory practice, concerning basic artistic stage, chemistry and art, dermocosmetics, and laboratory practice level dermocosmetics production, on the learning performance of students. The application process consisted of two stages, namely an experimental stage and an artistic…

The aim of this experiment is to study and calculate the kinetic constant of a Heck reaction: the arylation of but-3-en-2-ol by iodobenzene catalyzed by palladium acetate in presence of triethylamine in DMF. The reaction leads to a mixture of two ketones. Students use GC analysis to quantify reagents and products of reaction. They control the…

Core concepts can be integrated throughout lower-division science and engineering courses by using a series of related, cross-referenced laboratory experiments. Starting with butane combustion in chemistry, the authors expanded the underlying core concepts of energy transfer into laboratories designed for biology, physics, and engineering. This…

Describes a simplified diffraction experiment offered in a workshop with the purpose of illustrating to high school students the relation of science to society. The radii determined for cigarette smoke particles range from 0.2 to 0.5 micrometer in this experiment. Included is a description of the diffraction theory. (CC)

Describes a student kinetic experiment involving second order kinetics as well as displaying photochromism using a wide variety of techniques from both physical and organic chemistry. Describes measurement of (1) the rate of the recombination reaction; (2) the extinction coefficient; and (3) the ESR spectrometer signal. (Author/JN)

A description is given of a chemically-oriented curriculum on "Smoking and Cigarette Smoke" for science and nonscience oriented high school students. Laboratory activity is emphasized. (SA)
