The basic principles of mechanical engineering are Isaac Newton's three laws of motion regarding force, acceleration and deceleration, and actions and reactions. Working with these basic rules, today's engineers continue to create inventions that make our lives easier.
In Tunnels, early fluent readers will learn about the engineering that goes into building tunnels and making them safe. Vibrant, full-color photos and carefully leveled text will engage young readers as they explore the built world around them. An infographic illustrates aspects of the Channel Tunnel, and an activity offers kids an opportunity to extend discovery. Children can learn more about tunnels using our safe search engine that provides relevant, age-appropriate websites. Tunnels also features reading tips for teachers and parents, a table of contents, a glossary, and an index. Tunnels is part of Jump!'s Amazing Structures series.
