Warm-Up Activity
Directions: Please respond to the questions below in your notes.
• In your own words, “What is Engineering?”• In your own words, “What is Science?”• In your own words, “What is Technology?”
What is Engineering?, What is Science?, What is Technology?
Objectives
• WW know what engineering is.• WW know the difference between an engineer
and scientist.• WW will be able to define technology and give
examples of technology advancement.
What is Engineering?, What is Science?, What is Technology?
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 Engineering?, What is Science?, What is Technology?
Engineering is…• “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.”
What is Engineering?, What is Science?, What is Technology?
Engineers build things to make people’s lives better
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.
What is Engineering?, What is Science?, What is Technology?
• 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.

Characteristics of Engineers…
Thorough – understand the background Math and Science for what they are designing
Creative
Enjoy solving problems
Understand the importance of cost of design and manufacture
Highly ethical and concerned about safety of designs
Work well in teams
Excellent communicator

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
