Many analogies have become ineffective due to changing lifestyles and demographics. With the high degree of diversity found in most student populations, no single analogy can be expected to be effective. This article presents two new analogies for collision theory based on arcade games and on the interactions between salesclerks and customers in a store. The uses, limitations, and possible extensions of the analogies are discussed.
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.
Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students.
Occasionally, collections of JCE back issues become available for donation to individual teachers, schools, or libraries. JCE matches collections with interested recipients. Recipients pay shipping costs or pick up the collection.
