In Diseño y Construcción en la Tierra, young readers will learn how engineers dig, move, and level the ground in order to make houses, tunnels, dams, and more!The Mi Biblioteca de Ingeniería/My Engineering Library series gives an introduction to a variety of engineering and design topics for beginning readers based on NGSS. From learning about how engineers design rockets to how they build structures underwater, these informative books present complicated information in easy-to-understand language with kid-friendly examples and diagrams. Each book includes a glossary, index, and an engineering design activity to support further comprehension.
