"Engineers are the folks who use science to solve problems. They use their knowledge and skills to design, build, and repair the things we use, from roads to robots. This book introduces readers to different fields of engineering: mechanical engineering, aerospace engineering, energy and alternative-energy engineering, materials engineers and robotics. Grab your ID badge (page 7) and head to the lab! First lessons at the Engineer Academy are about machines, and there are plenty of hands-on activities exploring levers, pulleys, and wheels. Yes, you design a car; no, it doesn't have an engine. In aerospace class you compare wing properties, and in robotics class you make a 'grabber arm'. There are electrical circuits to connect, and a press-out wind turbine to construct. In addition to making things, engineers study the properties of materials such as plastics and metals. Those properties make each material useful for different tasks--for example, glass makes a better window than brick. The book ends with the Engineers' Code, something we could all use in our lives. For example: working safely and keeping ourselves and other people free from harm, and making sure that we understand what needs to be done before diving into a project." -- Ithaca Child, "Alexander's Library"
