| Abstract |
|
Most students easily understand melting, vaporization, boiling, condensation, and freezing based on their daily experiences with water. The conversion of a solid directly to a gas, sublimation, and the conversion of gas to solid, deposition, may be more difficult to grasp because they are unfamiliar. Seeing these phase changes alongside evaporation and condensation may help students to better understand these processes. This Activity illustrates sublimation/deposition with para-dichlorobenzene (mothballs) and evaporation/condensation with water.

| Chemistry Teacher Connection |
| The Division of Chemical Education (CHED) of the American Chemical Society (ACS), along with the Journal of Chemical Education is offering a new value called the "Chemistry Teacher Connection" (CTC). This product is created especially for high school chemistry teachers. It offers an online-only subscription to CLIC along with membership in the Division of Chemical Education. Normally, these two items would cost $65 per year, but are available as the CTC for only $40 a year. CTC subscribers will receive access to all articles and accompanying supplements shown on the CLIC website. This will include all published JCE items that have been designated in a print issue's table of contents as being of interest to high school teachers, from 1996 through the current issue. |
| C & EN CLICs |
| Chemical & Engineering News is a professional chemistry journal published weekly to keep the 158,000 members of the American Chemical Society, the world's largest scientific society, informed of important developments in chemistry, industry, and business. Through special arrangement with the ACS, the Journal of Chemical Education is now able to provide its members with online access to C&EN articles that have been chosen specifically for secondary science instructors and their students. |
JCE Collections Available
|
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.
