Bridges and tunnels are lifelines
People have tackled seemingly insurmountable obstacles, including vast
canyons and mountain ranges, to design and construct these amazing
passageways. Bridges and Tunnels: Investigate Feats of Engineering
invites children ages 9 and up to explore the innovation and physical
science behind structures our world depends on.
Trivia and fun facts illustrate engineering ingenuity and achievements.
Activities and projects encourage children to learn about the
engineering process and to embrace trial and error. Children will engage
in a hands-on exploration of Newton's Third Law of Motion and of forces
that push and pull on structures. They'll make an egg bungee jump and a
soda pop can engine. They'll experiment with a triangular toothpick
dome, liquefaction, and corrosion. In Bridges and Tunnels: Investigate
Feats of Engineering, children will explore their own engineering and
building skills as they create several bridge models.
