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.

"Every James Rollins delivers mach-speed mayhem, throat-clutching suspense, high-style adventure, and a terrific story told terrifically." —Steve Berry, author of The Warsaw Protocol

Combining science, history, and breakneck suspense—and a secret tied to the Book of Genesis—Altar of Eden is sure to satisfy every James Rollins fan while winning over a slew of new converts.

Meet Jeremiah Adams. There are two of him. The offer is too tempting: be part of a scientific breakthrough, step out of his life for a year, and be paid hugely for it. When ViMed Pharmaceutical asks Jeremiah to be part of an illegal cloning experiment, he sees it as a break from an existence he feels disconnected from. No one will know he's been replaced -- not the son who ignores him, not his increasingly distant wife -- since a revolutionary drug...

"Provides children with instructions and tips on how to build structures for a variety of activities"--Provided by publisher.

"Kids love construction! From bridges to buildings, this book is filled with incredible things that young engineers can design and build themselves. They'll learn how structures are built, what goes on at construction sites, and the ways simple materials like rocks and dirt helped create our modern world. This book keeps kids on track with step-by-step instructions for building paper cup towers, railroads, and more. They'll find out about the infrastructure...

The pendulum clock was the standard for precise timekeeping for centuries. Plan and build one using your newly acquired knowledge of gears. Start by exploring why a pendulum keeps accurate time. Then calculate an appropriate pendulum length for the clock. Design the escapement mechanism and gear train, then add a suitable power source to keep the pendulum swinging.

Focus on the dominant source of electricity in the U.S. today: coal. Begin by reviewing concepts from thermodynamics that explain how power plants work. Then follow the processes that turn a hopper full of coal into abundant electrical power, extracting the maximum amount of energy along the way..

In robotics, the most important problem mobile robots must solve is how to navigate, or move with purpose, in the world. Here, learn how simultaneous localization and mapping (using internal models, beacons, and dead reckoning navigation) is the key to a robot’s autonomy in both structured and exploratory situations..

Look beyond recycling to the higher goal of sustainability. Then close the course by considering the Great Northeast Blackout of 2003. Caused by inadequately pruned trees and a software bug, this cascading sequence of infrastructure failures holds important lessons for the world of everyday engineering..
