Explore Canals and Dams!: With 25 Great Projects

Did you know that hydropower supplies 16 percent of all electricity worldwide? And there are more than 57,000 big dams around the world Explore Canals and Dams With 25 Great Projects invites kids ages 7 though 10 to investigate the waterways that help the world run Through fun facts and engaging content, readers explore record-breaking structures such as the Panama Canal and Hoover Dam. They also learn about the physics that make canals and dams work Elementary-aged kids discover how hundreds of years of innovation created the canals and dams we know today and how this technology affects people and the environment. Discover how one dam can both supply electricity to entire cities, and flood entire towns, and how one canal can cut trade routes in half Through 25 hands-on projects that use materials found around the house or classroom, kids will explore the mechanisms that make canals and dams work. Engaging STEM projects and experiments, such as engineering a beaver dam and experimenting with water, help kids break down the small processes behind big structures By combining science with fun facts, jokes, activities, and experiments, kids will have an exciting adventure exploring the world's canals and dams, while links to primary sources offer ample opportunity for further student-led exploration. Explore Canals and Dams is part of a set of four Explore Engineering books. In the Explore Engineering series, readers ages 7 to 10 learn the physics behind the things they build: Why does a tower of blocks eventually fall? Why does a tunnel sometimes cave in? Through a series of focused, science-minded activities that require critical thinking paired with creative trial-and-error attempts at building, readers develop foundational understanding of the physics that guides the building and maintenance of bridges, canals, tunnels, and skyscrapers. Other titles in the Explore Engineering set include Explore Bridges , Explore Tunnels , and Explore Skyscrapers
