  1. Obj. 1.03 Analyze and Assess the evolution and influence of technology.

  2. Background Information • Begins with first primitive tools developed by man in the Stone Age • Increasing at an exponential rate

  3. Stone Age • 250,000 BC – 3,000 BC • Most tools made of stone • Tools used for agriculture and hunting • Time for survival

  4. Bronze Age • 3,000 BC – 1,200 BC • Bronzemetal alloy made of copper and tin • Tools easier to shape, more durable and useful

  5. Iron Age • 1200 BC – 500 AD • Iron metal, when alloyed with other materials is stronger than bronze • Many people began to move from farms to develop towns and cities • Tools made of iron and steel • Plow and irrigation enabled fewer farmers to grow more food

  6. Middle Ages • 500 AD – 1500 AD • Brought about a number of technological developments that led to industrialization • Agricultural advances produced a surplus of crops • Led to increased trade • Increased trade created bigger markets • Spinning wheel helped jumpstart the textile industry

  7. Renaissance • 1450 AD – 1700 AD • Time of rebirth in arts and humanities • Leonardo da Vinci created drawings and written descriptions of things that were later developed in the 20th Century

  8. First screwdriver invented as gunsmiths tried to adjust their gun mechanisms • Gutenburg invented the printing press • Enabled information to be disseminated throughout the world • First used for the distribution of the Bible

  9. Industrial Age • 1700 – 1940 • Factories took over the production of most products • People began to buy items and migrate toward cities for jobs • Trade over long distances increased which led to need for fast, reliable, efficient transportation systems

  10. Communication advances accelerated information and coordinate systems • Structural systems were forced to improve as cities began to grow up instead of out • Mechanization of the farm • Invention of steam engine • Products gave people more leisure time and children more time to spend in school

  11. Information Age • 1940 – present • Marked by development of computer • New developments are often outdated before the finished product arrives at the store • Microchip (integrated circuit) revolutionized the world of electronics and made communication faster, cheaper, more powerful

  12. Research in energy systems to make them more efficient and less harmful to the environment • Manufacturing systems are highly technical and require specialized education • Structural systems are constantly changing to incorporate new materials and creative approaches to efficient building

  13. Emphasizes processing and exchanging information • More inventions have been developed during this period than throughout the entire course of history
