Summary:

"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.
