Ancient Science (Prehistory - A.D. 500)
Science Highlights: A Gareth Stevens Timeline Series
There is an incredible timeline of scientific development that occurred before we could record our history. Walled communities, calendars to track time, early irrigation systems, and domestication of animals all occurred in prehistory. Readers will be taken on a journey of scientific discovery of very ancient times--learning that a great deal of our lasting technologies stem from a not-so-primitive past. Sidebars and timelines support the main narrative.
