In the Laboratory
A Laboratory Experiment Using Molecular Models for an Introductory Chemistry Class
Shahrokh Ghaffari
Department of Chemistry, Ohio University–Zanesville, Zanesville, OH 43701
Cover
August 2006
Vol. 83 No. 8
p. 1182
Abstract
A new approach to using molecular models in teaching general chemistry concepts is presented. This has been designed for the first-time chemistry or nonmajor students and only applies to simple molecules and formulas. This approach can be used both as a laboratory experiment or classroom exercise. The purpose of using a molecular model is to provide students with a visual aid to conceptualize different basic topics in chemistry and become active learners. Students construct molecular models and use them to balance simple chemical equations, demonstrate the law of conservation of mass, and discover the relationship between mole and molecules and atoms.
Supplement
Instructions for the students including pre- and postlab questions are available.

Chemistry Teacher Connection

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
