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. -- Amazon
