This is the model lesson to be used against the debugging challenge. Look at this project and then look at the project at https://scratch.mit.edu/projects/186169313 and try to debug it. The two characters have a conversation about atoms at a disco hall/stage and then move outside where you are supposed to see a nitrogen atom. Hovering over the parts of the nitrogen atom tell you about them (electrons, protons, and neutrons). Then, you have to get Ruby through a maze without touching a wall or a moving electron. Once you get to the end, you will be sent to a movie theater where the characters tell you goodbye.
