Ancient civilizations come to life as children see how archaeology uncovers the mysteries of the past. It allows children to read about many ancient civilizations like the Babylonian, the Shang Dynasty, and the Sumerians. Students discover how the great Egyptian pyramids were built and how the lost city of Troy was finally found.
