Students in Discovery 6 begin their inquiry project apprenticeship by following a structured sequence of design thinking. Students generate questions, research Rube Goldberg and RGMs, define a task for their RGM to complete, make a list of possible objects to include, and draw a plan for how their energy exchanges will work within their machine. During our first Discovery Marathon of the semester, students try connecting all of their RGM into one long chain reaction. Students exhibit creative and critical thinking, perseverance, collaboration, and grit to get all of these machines to work. Here are a few of our most recent designs.
