Tell us what you think of Chemistry 2011 -- we welcome both positive and negative comments. Have any problems using the site? Questions?
Chemistry2011 is an informational resource for students, educators and the self-taught in the field of chemistry. We offer resources such as course materials, chemistry department listings, activities, events, projects and more along with current news releases.
The history of the domain extends back to 2008 when it was selected to be used as the host domain for the International Year of Chemistry 2011 as designated by UNESCO and as an initiative of IUPAC that celebrated the achievements of chemistry. You can learn more about IYC2011 by clicking here. With IYC 2011 now over, the domain is currently under redevelopment by The Equipment Leasing Company Ltd.
Are you interested in listing an event or sharing an activity or idea? Perhaps you are coordinating an event and are in need of additional resources?
Within our site you will find a variety of activities and projects your peers have previously submitted or which have been freely shared through creative commons licenses.
Here are some highlights: Featured Idea 1, Featured Idea 2.
