A-maze-ing Tunnels

A-maze-ing Tunnels

The underground city of Derinkuyu was made of a series of tunnels and caves, which could fit about 20,000 people! The city had stables, cellars, storage rooms, and chapels, just like an aboveground city. You can make your own tunnel city.

Build the Eiffel Tower

Build the Eiffel Tower

From The Science and Technology of Marie Curie

Built in 1889 for the World Exposition, the Eiffel Tower honored the French Revolution. It also showcased national engineering and design expertise to an audience of global visitors. Originally intended as a temporary monument, it remains one of the world’s most visited landmarks. The structure of the tower itself is actually quite simple! To understand how its rivets and beams join, build a model of your own.

Make Your Own Zibaldone

Make Your Own Zibaldone

From The Science and Technology of Leonardo da Vinci

A zibaldone is the Italian word for “a heap of things.” This is what Leonardo’s notebook was called. He collected a heap of ideas, observations, questions, and experiments on the pages of his notebooks, putting everything he saw or thought into the same book, instead of having different notebooks for different topics. And he used every corner and both sides of every page. In the 1400s, books and paper were more plentiful than they had...

Experiment with Homemade Soap

Experiment with Homemade Soap

From The Science and Technology of Ben Franklin

Back when Ben Franklin was a kid, making soap was a smelly affair. It’s much easier—and more fun—today. Have an adult help you with the knife and the hot glycerin (soap). Caution: An adult must help you melt the glycerin.

“This is a good nonfiction STEM-based book that provides a collection of activities perfect for enthusiastic readers or to combine with a makerspace. . . .If you are looking for new engineering books for upper elementary school students this book would be a good choice. Recommended

Ming Lu, Professor of Construction Engineering & Management, University of Alberta
Tunnels! provides a fascinating account of history, evolution, and current state of tunnel engineering. Complex engineering fundamentals are explained in straightforward language and fun illustrations. Kudos to the publisher and author on a job well done to decipher the code of tunnel design and construction while engaging the curious mind of a young reader in engineering.”


Detailed Book Description

Moles, beavers, rabbits . . . these animals burrow tunnels in the ground every day! What other kind of creature makes tunnels? Humans!

In Tunnels! With 25 Science Projects for Kids, children ages 7 to 10 explore the fascinating world of passageways beneath the ground, dug deep within the earth through soil and rock. But why dig through rock to make a tunnel? Tunnels give people a way to travel and transport goods from one place to another. Readers learn about the engineering and construction that go into every tunnel made, whether it's being dug under roads, under oceans, or under cities. Links to primary sources for kids offer a unique, interactive learning experience, while fun facts, engaging illustrations, timeline, glossary, and lots of resources keep kids wanting to learn more about the engineering design process.
