This digital lab introduces the concept of how quantum mechanics and light relate with respect to the Hydrogen atom. The module revolves around the Hydrogen Atom Simulator, a Bohr model version of a idealized hydrogen atom as it interacts with photons of various wavelengths. Watch the electron jump to higher energy levels as it absorbs photons, then emit photon(s) and drop back to a lower level. Students can drag the electron between levels and shoot photons of different wavelength/frequency at the atom.
The module also includes an instructor's manual, student guide, worksheets, and background information requisite to understanding the concepts. The Thermal Distribution histogram gives a temperature dependent plot of occupied states for many, many atoms.
See Related Materials for two additional simulation-based resources devoted to the same topic, recommended by the editors.

This scaffolded interactive tutorial explores the probability map of electron orbitals, as learners build computer models of atoms by adding or removing electrons, protons, and neutrons. Guided inquiry
This 8-part interactive tutorial promotes understanding of basic concepts of light, intensity and frequency, photon absorption, and light interaction with matter.
