Introducing Scientific Reasoning with the Penny Lab
Robert F. Mauldin
Department of Natural Science, Shawnee State University, 940 2nd St., Portsmouth, OH 45662-4303
Cover
August 1997
Vol. 74 No. 8
p. 952
Abstract
Discovery labs require a thorough knowledge of the experiment. Towards this end, a brief history of the chemistry of the Lincoln Type Penny, tips for instructors, and experimental results for an introductory discovery lab, commonly known as the "Penny Lab," are presented. Considerable emphasis is placed on scientific reasoning as defined in Ronald Giere's Understanding Scientific Reasoning for use in this and other discovery labs. This experiment, only briefly described elsewhere, is excellent for introducing students to a number of topics including scientific research, experimental design, and the determination of density.
