Technology The means by which humans modify the world to address their wants and needs Involves objects and information 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 6 Copyright © Texas Education Agency, All rights reserved.

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 7 Copyright © Texas Education Agency, All rights reserved.

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? 11 Copyright © Texas Education Agency, All rights reserved.
