Abstract
This article describes a first year high school chemistry lab program which its author has developed over the past fifteen years. It features laboratory exercises that have have been altered ("transmuted") so that students may be evaluated on the accuracy of their work. For example, a traditional lab may ask that students determine the amount of product obtained from a reaction and compare it to theoretical value. In its transmuted form this lab would require that students either deduce the mass of a reactant from a measured mass of product, or perhaps predict the mass of product from a known mass of reactant. The author reports that lab exercises transmuted in this way work well with beginning students because the labs 1) make immediate sense to scientifically unsophisticated students, 2) challenge students to do their best work, 3) motivate by enlisting students' desires for social recognition, and 4) appeal to students' love of games and play.

A Discovery Approach to Three Organic Laboratory Techniques: Extraction, Recrystallization, and Distillation
Gail HorowitzJournal of Chemical Education2003 80 (9), 1039A Discovery Approach to Three Organic Laboratory Techniques: Extraction, Recrystallization, and Distillation
Gail HorowitzJournal of Chemical Education2003 80 (9), 1039This article describes three discovery-based experiments geared toward the beginning organic chemistry laboratory student. Each experiment focuses on one of the following purification techniques: extraction, recrystallization, or distillation. Unlike ...
Teacher Perceptions in the Selection of Experiments
Luis D. Montes , Mark G. RockleyJournal of Chemical Education2002 79 (2), 244Teacher Perceptions in the Selection of Experiments
Luis D. Montes , Mark G. RockleyJournal of Chemical Education2002 79 (2), 244Although much has been written concerning the techniques and benefits associated with inquiry-based laboratory methods, the use of this approach in both college and secondary school science classrooms is rare. In this article we present one exercise we ...

Stephen DeMeoJournal of Chemical Education2001 78 (3), 373The purpose of this study was to determine through a historical review of the literature some of the most effective ways to teach manipulative skills in chemistry. I reviewed chemical education journals, laboratory manuals, early American chemistry ...
On Laboratory Work
Dave OlneyJournal of Chemical Education1997 74 (11), 1343On Laboratory Work
Dave OlneyJournal of Chemical Education1997 74 (11), 1343This paper offers some suggestions on making lab work for high school chemistry students more productive, with students taking an active role. They include (1) rewriting labs from manuals to better suit one's purpose, (2) the questionable use of canned ...
