There are also several awesome books about Jane Goodall and how she would sit and watch the animals. "The Watcher" is one of them http://www.amazon.ca/Watcher-Jane-G...d=1398731265&sr=8-2&keywords=the+watcher
Another one my son liked was about Albert Einstein as a boy: "On a Beam of Light" http://www.amazon.ca/Beam-Light-Sto...31229&sr=8-1&keywords=on+a+beam+of+light
