JCE 92.08—August 2015 Issue Highlights

Using Models and Modeling To Teach

The August 2015 issue of the Journal of Chemical Education is now available online to subscribers.  This issue includes articles on modeling instruction; Lewis dot structure model; molecular models; using models to teach crystal symmetry; introductory activities and labs; organic chemistry investigations and tools for engagement; enabling chemistry training for low vision or blind students; impact of chemical education research; celebrating the work of Melanie Cooper; forensic chemistry articles from past issues.

Cover: Modeling Wildfires in the Lab

Wildfires cause substantial losses in property and lives every year. In the United States alone, an estimated annual total of over 60,000 wildfires burn between 12,000 and 40,000 square kilometers of land. In Wildfires in the Lab: Simple Experiment and Models for the Exploration of Excitable Dynamics, Christian Punckt, Pablo S. Bodega, Prabha Kaira, and Harm H. Rotermund present model experiments and computational approaches for observing and analyzing wildfire dynamics. The cover image shows a time sequence of a “wildfire” on laboratory scale. The model forest on fire is made of an array of matchsticks, illustrating the violence of a real-life situation.
