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?”


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.


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?


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.”


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.


• 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.


What Engineers Do

Design products, machines, or processes to perform a purpose safely and economically

Analyze existing products for safety or improvement

Repair products or systems

Solve important problems for society without causing harm


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

• What do engineers do?

• What is the difference between a scientist and an engineer?

What Is Technology? • How we modify the world to address their wants

and needs • Involves an artifact, or a system • Includes phones and televisions, and also things

like spoons and running shoes • It even includes the kernel of grains in our cereal
