In 3D Engineering: Design and Build Your Own Prototypes, young readers tackle real-life engineering problems by figuring out real-life solutions. Kids apply science and math skills to create prototypes for bridges, instruments, alarms, and more. Prototypes are preliminary models used by engineers -- and kids--to evaluate ideas and to better understand how things work.
