Entry Events
Events that will be used to introduce the project to studentsRube Goldberg Failure Analysis
The class watches a video clip of a Rube Goldberg machine failing spectacularly. Students are then tasked with identifying the points where physics principles (force, mass, acceleration) were misapplied, leading to the failure. This sets the stage for designing their own successful experiment.Portfolio Activities
