The Giant 3D Periodic Table: A Community-Built, Interdisciplinary Model for Chemical Education and Public Engagement

In celebration of the International Year of the Periodic Table (2019), the New York Section of the American Chemical Society (NYACS) created a 12 ft × 12 ft × 11 ft community-built, three-dimensional periodic table, displayed at the New York Hall of Science. Contributors from 56 institutions (62 including unveiling participants) designed 118 element panels that combined essential chemical data with original artwork. Guided by visualization, constructivist participation, and informal science education, the project transformed a familiar chart into an immersive, collaborative learning resource. Surveys conducted during the Chemistry Spectacular─held after the unveiling when the exhibit was in its third day of display─showed strong impact: 95% of visitors reported learning something new, and perceptions of chemistry shifted from “boring” to “awesome”. A case study at the United States Merchant Marine Academy further demonstrated gains in conceptual understanding, creativity, and ownership. This case study highlights how interdisciplinary, cocreated exhibits can advance chemistry education, broaden public engagement, and cultivate belonging in science.
