Engineering Our World

Dams are important engineering marvels. However, if not built correctly, dams can cause catastrophic damage to our buildings, land developments, and the natural world. With this book, readers will learn about the different types of dams, the materials needed to build them, the steps to preparing the dam site before construction begins, and the designing process. Readers explore the many benefits of dams, such as harnessing the power of water to create electricity and diverting water for irrigation. A step-by-step project helps young engineers conceptualize how much work is involved in building a dam and how important they truly are.

High above our heads, orbiting Earth, are huge technical wonders called satellites. These instruments do so much for us, from helping our cars navigate through GPS to informing meteorologists' predictions of the weather. Making these satellites is no small feat, and they are very expensive. A typical satellite can take several years to build and costs nearly millions of dollars. This STEM-connected volume explores the complex engineering required to build, test, launch, and analyze satellite systems in use today, and includes a look into where this fascinating technology is headed in the future.

The first submarine was built in the 1600s. Engineering capabilities have advanced immensely since then, making submarines one of the world's most interesting means of transportation. Engrossed readers will learn about the ingenious engineering behind submarines, from construction to the ins-and-outs of how they work. STEM concepts help readers understand the science that makes submarines possible. Accessible text paired with full-color photographs and intriguing fact boxes will draw readers in and aboard this underwater marvel.

Imagine building a floating airport. Aircraft carriers are the crowning achievement of navy ships. Each takes thousands of people several years to build, and can cost over 10 billion dollars. Inside is a miniature city for a crew of 6,000, and on top is a huge flight deck. Powerful catapults are ready to launch jets off the runway when needed. Enthralled readers will explore the creation of these mobile ocean giants in this fascinating volume filled with striking images and essential STEM concepts that support the elementary science curriculum.

Although they may seem commonplace, in truth houses are amazing feats of engineering. In order to build a house, a large team of specialized workers must labor together seamlessly. Who operates the heavy machinery required for construction? What are the duties and skills of a contractor, carpenter, mason, or electrician? What makes the walls and ceiling stand, and how does the roof keep the rain out? Readers will take an eye-opening look at home construction, learning what houses are made of and who builds them. The process is engagingly summarized in the steps of building a house.

Anyone who has visited an amusement park has likely seen the hills and loops of a roller coaster. For those who have felt the thrill of the ride, it's often the excitement of that first drop or the speed that follows that keeps them coming back for more. Before anyone can experience the adventure of a roller coaster, a lot of hard work must go into building it. Readers of this high-interest resource will learn all about the science and mechanics behind the construction of roller coasters. Aspiring engineers and amusement park enthusiasts alike will be captivated by this informative volume.
