My work is posted at: http://nell.tk/ Why shouldn't this be taught in schools?
Your list of questions does not correspond with how we organize our knowledge. The question "what are its parts?" can refer to geography or government or anatomy or chemistry or particle physics. Your question is a useful one but it needs a discussion of what it can mean. And to be meaningful, you would have to teach all of those subjects first. Your list of example subjects has many redundancies and no explanations.
