Where does change start?

This is a question that I have indirectly asked 5th and 6th grade students. I asked them to tell me one thing in their school or their neighborhood that they would like to change to make their education or community better. Next I asked them to tell me who would be the person who could make this change. Finally I asked them how do they see themselves as part of this change. How do you see yourself as part of the changes that need to happen in the world?
