1. Provide a big picture view of science to give the details a meaningful context. (In this case, the story of our own origins, relevant to our perspective on who we are and where we are headed.)

2. Help weaving big picture motivation provided by the series into the details of science curricula (complement broad-brush view with nitty-gritty details).

3. Building a community of people curious about the universe and our place within it (regardless of professional role: teacher, student, researcher, or other member of the public).
