You aren't asking a specific question here. I assume this statement is the thesis of your essay. Although we don't write essays for students here at enotes, I can give you some suggestions and get you headed in the right direction. For more ideas and details, follow the link below.
Since Scout is telling this story, the novel is a story of her childhood and that of her brother, Jem. You have the whole book to choose from for examples of their childhoods. Give specific examples of some of the events that reflect this statement. You might talk about the games they play or the events that occur that teach the young boy and girl some life lessons. You could also mention the way Atticus raises the two children or even about the people in their town who influence the children, such as Maudie Atkinson.
As far as segregation is concerned, you have no better example than the trial of Tom Robinson. What effect does Tom's trial have on the kids? What is the attitude of the townspeople toward blacks during this period of time? Give specific examples of the effects of racism on the town and the people in it. You could also mention Calpurnia, who has raised Jem and Scout.
