"Created to support NGSS, the Be An Engineer! series explains how different structures are designed by engineers to solve problems. Each title takes readers through the steps of the engineering design process to explain how an everyday structure is designed to overcome physical obstacles to meet peoples' needs. Real-world examples, vibrant photographs, and fact boxes reinforce learning, and readers design and create their own model structures. A link printed inside each book gives readers access to Crabtree Plus, a secure website with supplemental digital content, including engaging simulations and interactive activities that reinforce and extend key series' concepts."--,Provided by publisher.

Engineers design dams to help solve the challenges of providing drinking water and electricity to people's homes. Young readers will learn about the steps in the engineering design process and see what materials are used in construction to make dams strong enough to hold up against the strong forces of water, weather, and natural disasters. A link to interactive activities online plus an activity in the book allow readers to create stable dams.
