National Chemistry Week – October 18-24, 2026

This year’s theme is “Chemistry Under Construction.” During National Chemistry Week, North Jersey ACS partners with Liberty Science Center to present ChemExpo. The event has run for 25+ years and has brought local colleges, universities, and high schools to LSC to present their theme-related demonstrations. Delighted children, enthusiastic chemistry students, local industries, and NJACS volunteers come together annually to share and learn about the amazing nature of chemistry.
Join us on Saturday, October 24, 2026 from 12 pm – 4 pm at Liberty Science Center to celebrate ChemExpo.
