Framing the Lesson OBJECTIVE: We will differentiate between science, technology, and engineering. We will learn the difference between the scientific process and the engineering process. We will Define engineering and list characteristic and constraints in the engineering field. UNT in partnership with TEA. Copyright ©. All rights reserved. 2

Let’s Think Directions: Please take out a sheet of paper and respond to the questions below. Work with your partner. In your own words, “What is Engineering?” In your own words, “What is Science?” In your own words, “What is Technology?” Share with your table! UNT in partnership with TEA. Copyright ©.

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? UNT in partnership with TEA. Copyright ©. All rights reserved. 4

Engineering is the science, skill, and profession of acquiring and applying scientific, economic, social, and practical knowledge, in order to design and also build structures, machines, devices, systems, materials and processes. UNT in partnership with TEA. Copyright ©. All rights reserved. 5

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.” UNT in partnership with TEA.

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. UNT in partnership with TEA. Copyright ©. All rights reserved. 8

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 UNT in partnership with TEA.

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 UNT in partnership with TEA.

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 UNT in partnership with TEA. Copyright ©. All rights reserved. 15

Using a Microsoft Office Create your own version of what engineering means to you. Words, pictures, etc.. Also, include the engineering process steps ( can be a list or fancy chart) Print and turn it in the “In tray” (must have name and period on it). UNT in partnership with TEA. Copyright ©.
