dams

"Life in Sunrise Valley is tranquil, but beyond its borders lies certain death. A dangerous black fog looms outside the village, but its inhabitants are kept safe by an ingenious machine known as the dam. Pig's father built the dam and taught him how to maintain it. And then this brilliant inventor did the unthinkable: he walked into the fog and was never seen again. Now Pig is the dam keeper. Except for his best friend, Fox, and the town bully, Hippo, few are aware of his tireless efforts. But a new threat is on the horizon--a tidal wave of black fog is descending on Sunrise Valley. Now Pig, Fox, and Hippo must face the greatest danger imaginable: the world on the other side of the dam"--Dust jacket flap.

"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."--.
