National Chemistry Week 2024 focuses on the chemistry of photography

From Oct. 20 to 26, American Chemical Society volunteers from 114 local sections, four international chemical sciences chapters, and several student chapters hosted hands-on activities and demonstrations for National Chemistry Week 2024 (NCW 2024).

This year’s theme was “Picture Perfect Chemistry.” The volunteers educated thousands of members of the public about chemistry’s role in photography and imaging. They also distributed free ACS resources, including the magazine Celebrating Chemistry. This year, 72,750 copies in English and 7,750 copies in Spanish were distributed. In addition, 32 sections participated in an illustrated poem contest for K–12 students.

“NCW 2024 was a picture-perfect success with local sections and other groups of chemists hosting thousands of children and families at their events with exciting hands-on demonstrations of chemistry,” Lori Stepan, chair of the ACS Committee on Community Activities, says in an email.

Volunteers this year were required to adhere to the ACS Youth Protection Policy for the first time. Since Sept. 1, all volunteers at ACS-hosted outreach events are required to clear an ACS background check. “The new Youth Protection Policy for ACS volunteers was reported to move quickly and smoothly,” says Stepan. “Most volunteers felt that the safety and security of our younger participants was of utmost importance and willingly submitted their clearance materials.” As of Oct. 31, more than 1,500 ACS background checks had been completed, with an average turnaround time of 12 h.

The following are highlights of the NCW 2024 events:

The California Section supported the 2024 Science in the Park event at California State University, East Bay. The volunteers demonstrated with ultraviolet (UV)–sensitive color-changing beads, cyanotype imaging paper, and ferromagnetic fluid sheets that detect magnetic fields.

The Central Massachusetts Local Section created a demonstration explaining the photosensitivity of silver salts for students at the Boys and Girls Club of Leominster.

The Central Ohio Valley Section hosted an outreach activity at a fall festival at Heritage Farm Museum and Village in Huntington, West Virginia. Section members and Marshall University students helped children create nature art prints with cyanotype paper and sunlight and taught them to use diffraction glasses to view atomic emission spectra from helium and neon discharge lamps.

The Central Wisconsin Local Section ran an imaging activity at the University of Wisconsin–Stevens Point’s Homecoming and Family Day. Volunteers showed more than 50 children and their families how scientists use probes to image atoms and molecules.

The District of Columbia’s Chemical Society of Washington hosted activities at the Spooky Mad Science Expo in Alexandria, Virginia. More than 100 children and their families engaged in activities such as using magnets to explain the imaging of atoms, making UV light prints with stencils of the NCW logo, and viewing the security markings on a $5 bill.
