5 Learning Objectives Name the major divisions in the evolution of technology. Cite technological developments in each period of technological history. Identify characteristics of the Information Age. © Goodheart-Willcox Co., Inc.

6 Technology Defined People use technology every day but understand little about it. It can be primitive and crude, or complex and sophisticated. Technology is humans consciously using objects to extend natural abilities or potential to do work, resulting in artifacts or other outputs. © Goodheart-Willcox Co., Inc.

7 Features of Technology

8 The Economy of Technology
Products and services available in society are the result of technology. Nearly all technology is developed and produced by profit-centered businesses. Businesses change and improve their products and services. Each country’s economy is directly dependent on its ability to produce products and services that can compete in the world market. © Goodheart-Willcox Co., Inc.

9 Discussion What changes have been made to the automobile since it was first manufactured? (Library of Congress, General Motors) © Goodheart-Willcox Co., Inc.

10 The Good Aspects of Technology
Technology is a dynamic process, always improving on existing technology. Technology allows humans to communicate better and faster, travel more efficiently, and makes life more enjoyable through advanced forms of entertainment (virtual reality; video and computer games). (Keytec, Inc.) © Goodheart-Willcox Co., Inc.

11 The Bad Aspects of Technology
Technology also contributes to worldly problems when used improperly. It can cause pollution, unemployment, huge disasters, and soil erosion. Being technologically literate can help prevent misuse of technology. (U.S. Department of Agriculture) © Goodheart-Willcox Co., Inc.

12 Technology and Science
Technology and science are closely related, but are different. Science is examined through research of the natural world. Technology is concerned with development of products and structures to make our lives better. A third type of knowledge is humanities.

14 Types of Knowledge © Goodheart-Willcox Co., Inc.

15 The Evolution of Technology
Technology has been part of humanity for 2.5 million years. Early communities lived in primitive conditions. Civilized conditions came when humans began making tools, growing crops, engineering materials, and developing transportation systems. The technological developments of each age led to major changes in society. © Goodheart-Willcox Co., Inc.

16 Technology Through the Ages
(, Library of Congress, NOAA) © Goodheart-Willcox Co., Inc.

17 The Stone Age (1,000,000 – 3000 B.C.) Began about 2 million years ago.
Tools were made of stone and used to cut and pound vegetables, and cut meat from animal carcasses. Humans learned to harness fire for heating, cooking, and protection. The population being more productive meant that more people could live in a given area. © Goodheart-Willcox Co., Inc.

18 The Bronze Age (3000 – 1200 B.C.) Marked the discovery of copper and thus bronze. Humans used copper and copper-based metals as tools. Large-scale irrigation systems transformed agriculture so people did not have to depend on native vegetation and animal life for survival. Food storage, writing, navigation, and other basic technologies were developed and improved on. © Goodheart-Willcox Co., Inc.

19 The Iron Age (1200 B.C. – 1300 A.D. Iron and steel became the primary materials for tools because they were more plentiful and cheaper than copper and bronze. The alphabet came into general use, as did coins. Trade, transportation, and communication all improved, and civilization expanded. © Goodheart-Willcox Co., Inc.

20 The Middle Ages (500 A.D. – 1500 A.D. Known for various upheavals, as tribes continually fought for territory. The invention of the printing press by Johann Gutenberg in 1445 made books more available to most people. Other items discovered and improved on during this time included the magnetic compass and waterwheel. Paper money increased the amount of goods bought and sold. © Goodheart-Willcox Co., Inc.

21 The Renaissance (1300 – 1600 A.D.) The Renaissance led to improvements in the arts, literature, history, and political science, and discovery of new lands. Sketches for inventions, like a flying machine and a movable bridge by Leonardo da Vinci. Inventions between the 1300s and 1600s: Modified ships. Calculators. The telescope. The screwdriver. © Goodheart-Willcox Co., Inc.

22 The Industrial Revolution (1750 – Ongoing)
The Industrial Revolution began in England in the 1750s and moved to America in the late 1700s. Improvements in weaving and the steam engine, invention of the cotton gin and standardized parts. Workforce changed for more efficient production. Longer machine life, division of jobs, new material-handling devices, and management. © Goodheart-Willcox Co., Inc.

23 Discussion What positive and negative effects did the Industrial Revolution have on society? © Goodheart-Willcox Co., Inc.

24 The Information Age (Present)
Characteristics of the Information Age: Automatic machines and information-processing equipment. Trained technicians, technologists, and engineers. Blurring between production workers and managers. Constant job-related training and retraining. © Goodheart-Willcox Co., Inc.
