Technology Foundation of Engineering and Technology

Objectives: Define Technology List the basic features of technology Describe technology as a dynamic process List positive and negative features of technology Explain the difference between science and technology Name the major divisions in the evolution of technology Cite technological developments in each period of technological history Identify characteristics of the Information Age

Technology Defined What does it really mean? (students) How long has it been here? (students)

Technology is humans using objects to change the natural and human-made environment. Technology is conscious, purposeful actions designed by people to extend human ability or potential to do work.

4 Basic Features of Technology 1.Technology is human knowledge 2.Technology uses tools, materials, and systems 3.Application of technology results in artifacts (human-made things) or other outputs (pollution and scrap) 4.Technology is developed by people to modify or control the environment

Technology is Dynamic Dynamic means? Example-Floppy Disk –Other Examples? CHANGE

Positive and Negative Aspects of Technology? Negative????? –Examples Positive?? –Examples

Technology and Types of Knowledge Is technology applied science? NO…technology and science are related but different –Science might be about trees and mountains and critters –Technology is about the human built world

The World Can Be Understood with Science and Technology and Humanities Humanities-the study of how people behave individually(psychology) and in groups(sociology), what they value(religion and ethics) and how they express themselves(art, music and literature) Example-Smarthouse

Evolution of Technology Primitive conditions-determined by nature Civilized Conditions-humans exert their will on the natural scene –Evolution of civilization is directly related to the tools of the times

Stone Age 2 million years ago People used stone tools and learned to harness fire

Bronze Age B.C. Used copper and tin to make bronze Bronze was a stronger metal

Iron Age 1200 B.C. to 1300 A.D. Iron and steel became the primary materials for tools because they were more plentiful and cheaper More people could afford tools which created more opportunities for sustained technological advancement.

Middle Ages 588 A.D. to 1500 A.D. Germanic tribes invaded and conquered the Roman empire Tribes fighting for territory Printing Press invented by Johann Gutenberg in 1445 Magnetic compass Waterwheel-changed the power of water in mechanized energy Invention and adoption of paper money increased the amount of good bought and sold

The Renaissance 1300 A.D. to 1600 A.D Began in Italy Great cultural advancement European voyages traveled to America –Improvement in ships –Tools for farming were brought over Leonardo DiVinci drew flying machines and moveable bridges Calculator Telescope

Industrial Revolution 1750 A.D. and still For the last 250 years, technology has drastically changed the world Began in England Came to America in the late 1700’s Steam Engine, Cotton Gin, Power Loom Led to Continuous Manufacture: –Improved machine life because of interchangeable parts –Division of job into parts –Creation of material handling devices to bring work to workers –Classification of management as a professional group 1900’s-1908,

????????? What positive and negative impacts have come about from the industrial revolution?

Information Age PRESENT Characteristics: –Wide use of automatic machines and information processing equipment –High demand for trained technicians, technologists and engineers –Blurring of the previously sharp line between production workers and managers –Constant need for job-related training
