This is a great question!
There are some key differences between our HackEDU Break/Fix lessons and Experiments
HackEDU Break/Fix lessons are a dynamic web application. The lessons provide learners the opportunity to break and fix code
Experiments are a static set of code and are fix only
One other important note: HackEDU Break/Fix content is available to be added to Missions but Quests remain Experiments only.
