Engineers are Inventors!
Engineers use science and math to solve real world problems!
What are some of the types of engineers you have heard of?
Possibly:Chemical, electrical, mechanical, software, civil,
biomedical, and environmental. AND MANY MORE!
Look around you, virtually every manmade contraption you see was conceived of and created by an engineer!
SCIENCE vs. ENGINEERING SCIENCE
Analysis: ask questions, look for patterns, develop knowledge
Produce knowledge Characteristic activity:
research (learn about nature) Study of what is
ENGINEERING
Synthesis: integrate bits of knowledge to create something new
Produce processes and things (part of technology)
Characteristic activity: creative design
Study of what never was
ENGINEERING IS EVERYWHERE
Engineering gives shape to our world We all know cars, computers, airplanes, and
bridges are all products of imaginative engineering
But did you know bubble gum, baseball bats, movie special effects, roller coasters, and synthetic human tissue replacements are also engineering products?
ENGINEERING IS EVERYWHERE
Engineers design, create, or modify nearly everything we touch, wear, eat, see, and hear in our daily lives.
Their innovations and inventions fuel economic growth, fortify national security, improve healthcare, and safeguard the environment.
The First Engineer
Imhotep Designed the pyramid near Memphis, Egypt
around 2550 BC.
Imhotep He set a precedent by including temples,
pavilions, corridors, chapels and halls within the closed walls.
He was a commoner by birth. Which means he did not have a formal
education (that was only for the rich). At that time engineers learned the trade through
the apprenticeship system.
Imhotep
He became one of the king’s most trusted advisors.
His reputation lives on still today in many fictional stories such as:

The Mummy Returns
•Scientists discover the world that exists; engineers create the world
that never was." - Theodore Von Karman aerospace engineering
What is needed to
Create a Product?Example Science Technology Engineering Math
Pencil Discovery of graphite and the fact that rubber (eraser) will remove graphite
Creating a writing device that doesn’t use ink
Designing a device with graphite insert, exterior holder, and attached eraser
What is the optimal length, diameter, or shape for the device?
Engineering
Engineering uses scientific, technological, and mathematical knowledge to solve practical problems.
Engineers Can Do Anything
Invent – Develop a new product, system, or process that has never existed before
Innovate – Improve an existing technological product, system, or method

An electrical engineer may design a GPS for your vehicle.
A pharmaceutical/chemical engineer may find a cure for disease.
A computer engineer may build a computer the size of your watch.
A mechanical engineer may create a robot to discover water on a planet.
An agricultural engineer may evaluate the effects of global warming on food production.
Engineers Work to Solve Many Kinds of Problems
Engineers make our lives better
What are Some Types of Engineering?
Just as science is divided into separate fields such as biology, chemistry and physics, engineering is divided into a variety of disciplines. The five largest engineering disciplines are chemical, civil, electrical, industrial and mechanical. Engineers within all of these disciplines can work in product-oriented companies, government, or academia.
Aerospace Engineering Aerospace engineers design, analyze, model, simulate, and test aircraft, spacecraft, satellites, missiles, and rockets. Aerospace technology also extends to many other applications of objects moving within gases or liquids. Examples are golf balls, high-speed trains, hydrofoil ships, or tall buildings in the wind. Aerospace engineers are typically specialists in fields with fancy names such as aerodynamics, propulsion, navigation, flight testing, and more.
Biomedical Engineering This is an interdisciplinary field combining mechanical, electrical, and chemical engineering to study the human body. Biomedical Engineers study biology and medicine to develop technologies related to health care. They develop medical diagnostic machines, medical instruments, artificial organs, joint replacement parts, and prosthetic devices.
Chemical Engineering Chemical Engineers use their knowledge of physics, chemistry, and biology to discover and manufacture better plastics, paints, fuels, fibers, medicines, fertilizers, semiconductors, paper, and all other kinds of chemicals, by carrying out chemical reactions and purifications.
Civil Engineering The design and construction of buildings, dams, water treatment and carrying systems, air pollution controls, and transportation systems are the responsibilities of civil engineers. Subheadings of civil engineering include: geotechnical, environmental, structural, transportation, materials, and project management.
Computer Science and Engineering Computer scientists and engineers are involved in the development of both hardware and software for computers. They work on computer-related systems like CD-ROMs, modems and monitors, as well as cutting-edge projects including robotics and virtual reality systems.
Environmental Engineering Keeping the water, air and soil healthy are the responsibilities of environmental engineers. To accomplish this goal they deal with issues including waste management, pollution control and irrigation.
Electrical Engineering Electrical engineering deals with electricity, magnetism, and light and how it is used. Electrical engineers are found in a variety of companies including the computer, communications, and automotive industries.
Mechanical Engineering Engineers within this discipline tend to focus on one of three aspects of mechanical engineering; design, manufacturing, or energy/power. Cars, airplanes and toys are just a few of the areas in which mechanical engineers work.
Petroleum Engineering Petroleum engineers study the earth to find oil and gas reservoirs. They design oil wells, storage tanks, and transportation systems. They supervise the construction and operation of oil and gas fields. Petroleum engineers are researching new technologies to allow more oil and gas to be extracted from each well. They help supply the world's need for energy and chemical raw materials.
Now let’s take a look at some real life engineers and what they’re working on right now!
Separating Oil from WaterSeparating Oil from Water
Di Gao, a chemical engineer at the University of Pittsburg, invented a plastic-coated cotton material that could clean up the Gulf.
Designing Better CarsDesigning Better Cars
Marcus Ashford, a mechanical engineer at the University of Alabama, has invented a car engine with 80% less exhaust emissions.
Cleaning Up the Ocean
Alexandria Boehm is an environmental engineer who works on ways to clean up oceans near where people live.
Designing Space Colonies
Kimberly Jones is a civil engineer working on purifying water so that we can one day go to Mars!!!
Controlling Computers with Thoughts
Daniel Moran, a biomedical engineer at Washington University, has invented a way to play video games using only the human mind!
Listening for Cancer
• John Viator, a biological engineer, has invented a way to hear cancer cells.

How long do engineers have to go to school?
Engineers need a minimum of a college Bachelor's degree. That means they must finish high school and typically four years of college. A few engineering programs take five years. A college degree could take longer if you only attend college part time or perhaps attend during evenings.
How can I become an engineer?
First you will need a college degree. After that, many engineers seek a Professional Engineer (P.E.) license. It helps to begin preparations for all this at the middle school levels. Where possible, choose a well-rounded mix of classes with emphasis on math and science. Taken from discoverengineering.org
