Everything you need to understand or teach Letters from Atlantis by Robert Silverberg.
Letters from Atlantis is a fantasy tale about a civilization that might have flourished about twenty thousand years ago. Scientists have figured out a way to send people's conscious minds into the past, where they lodge in the minds of their ancient hosts. The main character is Roy Colton, who has been on several such time travels. Somewhere in a laboratory of the future his body lies sleeping, while his mind lives inside the mind of Ramifon Sigiliterimor Septagimot Stolifax Blayl (which translates as Beloved of the Gods and Light of the Universe), heir to the throne of Athilan, better known today as Atlantis; the prince is generally known as Ram. Through him, Roy gets a look at empires that existed in the remote past of human history, and Roy learns some of the secrets of a culture that historians had thought was only a figment of Plato's imagination....
