While retaining the typical high school separation between math, biology, chemistry, and physics, but given control over the curricula taught in those courses, do you think it is possible to teach a single very high-level concept such as the Krebs cycle in full complexity at a high school level (i.e. starting from algebra and very limited science education, completed in four full-time years)? This seems like a foothold for a potentially interesting restructuring of how we educate children, oriented toward depth in a few things to enlighten future breadth. I ask specifically about feasibility, since that seems like a necessary prerequisite to a discussion of beneficial value.
