In the Laboratory

Abstract
Gas laws are taught in most undergraduate general chemistry courses and even in some high school chemistry courses. This article describes the author's experience of using the laboratory to allow students to “discover” gas laws instead of the conventional approach of using the lecture to teach this concept. Students collected data using Vernier sensors and software and then graphed the data for analysis using Microsoft Excel. A brief description of the success of this approach—compared with the conventional approach—is also presented.
Supplement
Laboratory instructions, block diagrams for experimental setups, and student data and analysis for each of the four experiments are available.

 Caution! 
Experiments, laboratory exercises, lecture demonstrations, and other descriptions of the use of chemicals, apparatus, instruments, computers, and computer interfaces are presented in the Journal of Chemical Education as illustrative of new or improved ideas or concepts in chemistry instruction and are directed at qualified teachers. Although every effort is made to assure and encourage safe practices and safe use of chemicals, the Journal of Chemical Education cannot assume responsibility for uses made of its published materials. Many chemicals are hazardous. Precautions for the safe use of hazardous chemicals and directions for their proper disposal are described in the Material Safety Data Sheets and on the labels. We strongly urge all those planning to use materials from our pages to make choices and to develop procedures for laboratory and classroom safety in accordance with local needs and situations.
