Abstract: This lab allows students to have a “hands on” representation of the Bohr model (a game) which should help to make an abstract model more concrete. In this activity, which is intended to serve as an introduction to the Bohr model, students answer questions based on a small pinball game that simulates the Bohr model of the hydrogen atom by allowing electron (ball bearing) to be excited (launched) into various energy levels. Although most of the activity centers around a set of questions that the students must answer about the game, there is also a contest in the middle of the lab to keep things fun. There is also an optional section relating the game to transitions in a hydrogen gas tube. By playing the game and answering the questions, the students should emerge with a concrete understanding of how the Bohr model works.
