As we continue to make technological advances, the need to teach students about this ever-changing field becomes increasingly important. This book teaches students about different machines, including engines, computers, and airplanes, and how they work. In doing so, students will begin to see just how big of an impact technology has. By the book's end, readers will have just as many new questions as they do answers. Ending with a discussion about genetic engineering, which is being researched and talked about more now than ever, students will become eager to learn more about the world of technology.
