Bring atomic structure to life in your classroom! With this interactive AR activity, students don’t just read about protons, neutrons, and electrons—they explore them in 3D. Using technology, learners can scan a code and manipulate realistic atomic models, identifying subatomic particles and linking what they see directly to the Periodic Table. Page one guides them step by step through Helium, building confidence as they count particles and connect atomic number to structure. On page two, they
