(PowerKids Press, Jan. 1, 2017)
Humans have been scraping the sky much longer than most people think since the ancient Egyptian pyramids, in fact! In this exciting volume, readers will explore a comprehensive history of humanitys most vertically ambitious architecture and learn the fascinating geometry that makes such engineering possible. Theyll also investigate technologies these man-made heights require, such as escalators, elevators, weather-resistant materials, and more. Dizzying photographs will amaze even reluctant readers, and a fun map invites interaction. Complete with a hands-on engineering activity, this jaw-dropping volume is an essential addition to any library.
