National Chemistry Week (NCW) is a community based program of the American Chemical Society (ACS). This annual program unites ACS local sections, student chapters, technical divisions, businesses, schools, and individuals in communicating the importance of chemistry to our quality of life. NCW occurs annually during the week of Mole Day, which is October 23.
The mission of NCW is to reach the public, particularly elementary and secondary school children, with positive messages about chemistry to:
- Make a positive change in the public's impression of chemistry;
- Promote a mechanism for effectively mobilizing ACS local sections; and
- Motivate the ACS membership through local section activities.
NCW is administered by the ACS Office of Science Outreach which is part of the Education Division. The Committee on Community Activities (CCA) serves as the advisory group for outreach programs, and selects and develops the NCW themes and materials.
