If you have never seen this video, watch it.
What could be an amazing project, would be a school doing this with their community where they focus on one question, or have students develop a question that is important to them and have them interview 50 (or 10, or 20, or 100, whatever).
Asking the same question to different people, over and over again, would not only be a great research project, but can teach us about others and help our students (and ourselves) become more empathetic.
Would love to see this project (or something similar) done by students. So much could be learned by so many.
