CANALS AND DAMS!: WITH 25 SCIENCE PROJECTS FOR KIDS

Book ID/图书代码： 12580018C00161

English Summary/英文概要： Did you know that hydropower supplies 16 percent of all electricity worldwide? And there are more than 57,000 big dams around the world!

Canals and Dams! With 25 Science Projects for Kids 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.

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 Bridges!, Tunnels!, and Skyscrapers!

Chinese Summary/中文概要： 你知道水电供应了全世界16%的电力吗?世界上有超过57000座大坝!

Awards/获奖情况：Explore Simple Machines! With 25 Great Projects: National Science Teachers Association - " . . . This is not your usual activity book. Written for the student, with inquiry in mind, the explanations are simple and easy to follow, and there is an explanation of what is happening and questions to extend the learning. I would use this book with young scientists in my class, and I would also put the materials in a center for young children to explore, make, and do . . .I honestly didn’t think simple machines were fun or easy to understand. This book changed that for me and for my students."
