tunnels

"Carefully leveled text and vibrant photographs introduce early readers to the science and engineering behind the Channel Tunnel. Includes infographics, an activity, glossary, and index"--Provided by the publisher.

In 1928, nine-year-old investigator Lottie and her friends try to save the British Museum from shuttering its doors by looking for a buried treasure in a secret tunnel beneath the museum, only to discover they must solve a series of puzzles to find the treasure as well as their way out of the maze of passageways.

Tunnels examines the engineering concepts that make these important structures possible.

"Explores the engineering challenges behind building tunnels, as well as the creative solutions found to overcome those challenges"--Provided by publisher.

Drizzt Do'Urden, exiled from the surface world, struggles with solitude as he seeks out a new home in the labyrinth of the Underdark and watches for dark elves in pursuit.

"Examines the engineering concepts that make [tunnels]...possible"--Provided by publisher.

Kids will learn about the history of tunnels with Engineer It! Tunnel Projects. They will discover how tunnels are built. Then, build their own train tunnel, underwater tunnel, and more. Each project has color photos and easy-to-follow instructions. Young crafters will be budding engineers in no time!.

An introduction to the design process for tunnels.

The Berlin Wall went up in 1961. A year later a group of young West Germans risked prison, Stasi torture, and even death to liberate friends, lovers, and even strangers in East Berlin by digging tunnels under the Wall. When American channels NBC and CBS heard about it, they funded two separate tunnels in return for the right to film the escapes, planning spectacular prime-time documentary specials. President John F. Kennedy was not in favor of the plan because he was worried that the Soviets might take offense. As he said, "a wall is better than a war." In an era of escalating nuclear tensions, he approved unprecedented maneuvers to halt both documentaries, testing the limits of a free press.

"Created to support NGSS, the Be An Engineer! series explains how different structures are designed by engineers to solve problems. Each title takes readers through the steps of the engineering design process to explain how an everyday structure is designed to overcome physical obstacles to meet peoples' needs. Real-world examples, vibrant photographs, and fact boxes reinforce learning, and readers design and create their own model structures. A link printed inside each book gives readers access to Crabtree Plus, a secure website with supplemental digital content, including engaging simulations and interactive activities that reinforce and extend key series' concepts."--.
