Online simulation, teacher led guided notes, and hands on station activity to understand the structure of the atom and decipher Bohr models of atoms. Students investigate the properties of subatomic particles using a PHET simulation, complete notes over the composition of a Bohr model of the atom, then rotate through seven stations to calculate the protons, neutrons, electrons, and mass of atoms, determine the atom's identity, and classify the image as a neutral atom or ion.Please click this lin
