National Chemistry Week (NCW)

National Chemistry Week (NCW) Web Banner

NCW encourages ACS members and science enthusiasts to build awareness of chemistry at the local level. ACS local sections, schools, businesses, and individuals are invited to organize or participate in events in their communities with a common goal: to promote the value of chemistry in everyday life.

NCW 2018 was celebrated October 21-27, 2018 with the theme, "Chemistry is Out of This World."

During 2019’s International Year of the Periodic Table, NCW will be celebrated October 20-26, 2019 with the theme, "Marvelous Metals." The NCW 2019 edition of Celebrating Chemistry and other online resources will be available August 1.
