Episode 14: Inside the Unit: Atoms

Episode Summary In this episode, Chem walks through a practical sequence for teaching Atoms—from subatomic particles to isotopes and average atomic mass—plus why some topics don’t live in this unit (history of the atom, moles) and where to spiral in ions and the octet rule. You’ll get easy-to-run activities (Google Slides checks, PBS ChemThink, isotopes/average-atomic-mass activities), labs, and clear expectations for Chem 1 vs. Honors.
