What Is Engineering?
Do you ever find yourself wondering how something works or how a structure was
built? Well, then you might be destined for a career in engineering. The field of
engineering uses science to come up with solutions to problems in the real world.
Depending on what type of engineering it is, this process will look different in many
ways. Let's explore some of the major types of engineering in this lesson.
Roads, Airports and Bridges
Look around. Without a structural engineer, most of what you see around you
probably wouldn't be there! A structural engineer is someone who uses math and
science to invent, design, build, and care for structures, such as houses, roads,
bridges, dams, and airports. What's a Structure?Think about some structures around
you. What do they have in common? All structures must be designed by engineers so
that they can bear, or hold up, a particular load.
For example, a bridge has to be able to hold the weight of the people, cars, and trucks
that will cross over it every day. If it can't bear that load, it will collapse. Structural
engineers study the load that each structure must bear and figure out how to design a
structure that can withstand that load.

Civil engineering
Civil engineering is all about construction. Building skyscrapers, bridges and roads
is all done under the supervision of a civil engineer. One of their main priorities is

---

how these things can be built safely. How scary would it be if a bridge collapsed
almost every time someone crossed over it?! Thanks civil engineers for keeping
everyone safe! Civil engineers also come in handy after times of destruction, such as
after September 11th or Hurricane Katrina. Their expertise was needed to build
Freedom Tower in New York City, as well as reconstruct the levee that broke in New
Orleans.
