The Underground, the Metro, the Tube, the subway - whatever you call it, underground transit is a mark of a modern city public transportation system. Packed with historic and contemporary photographs, this compelling book will grab readers with an interest in subways and railways. Also included are underground escape routes and abandoned underground tunnel systems.
Imagine a street filled with horses and buggies, or the skies without airplanes! You might not realize that, before vehicles, it used to take days—even weeks—to visit friends or family! This title looks at major innovations in transportation over the years, and the ingenious inventors, scientists, and engineers who made them. With a little inventive thinking, what might you create to help us change the way we travel?
Engineers design tunnels to help solve transportation challenges for people everywhere. Young readers will learn about the steps in the engineering design process and see what shapes and materials are used in construction to make tunnels stable. A link to interactive activities online plus an activity in the book allow readers to create tunnels that can withstand weight, weather, water, and natural disasters!
Perhaps no two people in history exemplify the spirit of invention better than brothers Orville and Wilbur Wright. Born in the Midwest in the late 1800s, Orville was exceptionally good at creating mechanical devices, and Wilbur had a genius for ideas. The turn of the 20th century came during an age of invention and technological development. Inspired by a fierce worldwide competition to be the first to invent a machine that could fly and be controlled by a pilot, the Wright brothers tested and refined several prototypes. At last, on December 17, 1903, near Kitty Hawk, North Carolina, they achieved their pioneering flight. The brothers went on to develop machines and controls that made possible powered, fixed-wing flights and laid the foundation for pilot-controlled aviation as we know it today. They also founded the Wright Company, which built airplanes for the rising new industry of commercial aviation. Had Wilbur not died at the early age of 45, who knows what else the innovative pair might have accomplished.
Engineers design bridges to help solve the challenges of barriers that block the movement of people. Young readers will learn about the steps in the engineering design process and see how different types of bridges suit different types of obstacles. They will also discover what materials are used in construction to make bridges stable. A link to interactive activities online plus an activity in the book allow readers to create bridges that stand up to the forces of extreme weather and natural disasters.
