Welcome to Science Help Online for Chemistry.  This site has been designed to aid students who are learning Chemistry, by providing them with additional lessons, worksheets, and review materials.  Each of the lessons on this site were written by Greg Curran, a Chemistry teacher and the author of Homework Helpers: Chemistry.  Most of the support materials were produced by the students of Fordham Preparatory School.  
     Please note that this site is very much a work in progress.  Many of the lessons have not yet been completed.  I apologize for any inconvenience this may cause.  We hope that you will still find the site useful, and pass the link along to your fellow classmates.  The "search" feature is now functional.
