Project name
In this lesson students explore a model of a molecular beam experiment in which two water molecules collide at high speed and break apart into their component atoms. In analyzing the ratios of hydrogen and oxygen produced by the collision, students notice that there is something wrong. Investigating the code of the model leads to the discovery of a problem that students can fix. Students can test their solution to fixing the model by running the model and seeing if it produces the components in the correct ratio.
