3. 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?

4. 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.”

6. 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.

7. Engineering is a form of problem solving.
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.

11. 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

12. Involves the design, manufacture, use, and repair of the object
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

13. 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

14. The Scientific Process
Ask and define the question.
Gather information and resources through observation.
Form a hypothesis.
Perform one or more experiments and collect and sort data.
Analyze the data.
Interpret the data and make conclusions that point to a hypothesis.
Formulate a "final" or "finished" hypothesis.

15. The Engineering Design Process
Iterative!
1. Understand the need: What is the problem? What do I want to do? What are the project requirements? What are the limitations? Who is the customer? What is the goal? Gather information and research.
2. Brainstorm and design: Imagine and brainstorm ideas. Be creative. Investigate existing technologies and methods to use. Explore, compare and analyze many possible solutions. Select the most promising idea.
3. Plan: Draw a diagram of your idea. How will it work? What materials and tools are needed? How will you test it to make sure it works?
4. Create: Assign team tasks. Build a prototype. Does it work? Talk about what works, what doesn’t and what could work better.
5. Improve: Talk about how you could improve your end product. Make revisions. Draw new designs. Make your end product the best it can be.

16. The seven key resources for engineering are:
People
Energy
Capital
Information
Tools and machines
Materials
Time
Skip this slide if you run out of time
A resource is something that has value and which can be used to satisfy human needs and wants. Tools and machines allow humans to do things that are not possible with human power.
Economics:
Analysis of production, distribution, and consumption of goods and services
Opportunity costs, economic incentives, and corporate culture
