Questions to ponder:
• What is the difference between science and
technology?
• What are the greatest engineering accomplishments
of the 20th century?
• How do newer engineering accomplishments
compare to those throughout history?
• How does technology impact the world?
• What is the difference between innovation and
invention?
• What is an ethical design dilemma?
• Why did engineering societies develop standards?

ABET defines engineering as:
• “The profession in which knowledge of the
mathematical and natural sciences, gained
by study, experience, and practice, is
applied with judgment to develop ways to
use, economically, the materials and
forces of nature for the benefit of
mankind.”

Engineer
• A person who designs products, structures, or
systems to improve peoples lives
• Mathematics is the language of science,
engineering, and technology.
• Engineers use math to describe objects in great
detail, and mathematical models can test designs
without actually building them.
• Engineers use scientific principles to guide their
design.

5
• Engineers work in teams, and planning and
design is a large part of their work.
• Engineering is a form of problem solving.
• Engineers work in teams because different
people have different skills and can look at
problems in different ways.
• An engineer must look at problem criteria and
solution constraints.
• Engineering involves design and construction.
• Engineering is iterative.

Technology
• The means by which humans modify the
world to address their wants and needs
• Involves an artifact
• Includes phones and televisions, and also
things like spoons and running shoes
• It even includes the kernel of the grass
grains we use in our cereal

• Technology often involves a system, and
includes the people, infrastructure, and
processes.
• Involves the design, manufacture, use,
and repair of the object
• The innovation, change, or modification of
the natural environment to satisfy
perceived human needs and wants
• Human innovation in action that involves
the generation of knowledge and
processes to develop systems that solve
problems and extend human capabilities

10
Science
• Involves knowledge about the natural
world
• Often involves knowledge for its own sake
• Discovers and explains what is
• Engineering involves creating what has
never been
