The ACS Education staff, with a special thanks to the University of Puerto Rico Aguadilla Student Chapter of the American Chemical Society created the teaching activity, Organizing the Periodic Table to celebrate IYPT. The illustrations on the activity cards were created in 2015 by student members of the ACS ChemClubs.

In this activity, students are challenged to organize elements into the shape of the periodic table based on trends in data. Students are given a set of cards, each card representing an element, and containing five data points for consideration. The data that students will analyze includes atomic mass, atomic radius, melting point, density and electronegativity.
