Today, technological development is based on scientific knowledge and engineering design. © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

6. The History of Technology The History of Technology can be divided into nine distinct periods of time: © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology Paleolithic Age Mesolithic Age Neolithic Age Bronze Age Iron Age The Middle Ages The Renaissance Industrial Age The Information Age

7. The Paleolithic Age The Old Stone Age or in Greek (palaios – “old”) and (lithos – “stone”) Time Period: 500,000 BC – 10,000 BC Impacts on history: Improved diet and enhanced security enabled early humans to increase the population. Artifacts: Stone axes, bone needles, hearth sites © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

8. The Mesolithic Age The Middle Stone Age or in Greek (mesos – “middle”) and (lithos – “stone”) Time Period: 10,000 BC – 4,000 BC Impacts on history: The gradual domestication of animals and agriculture led to settled communities. Artifacts: Leatherwork, fishing tackle, stone circles © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

9. The Neolithic Age The New Stone Age or in Greek (néos – “new”) and (líthos – “stone”) Time Period: 4,000 BC – 2,300 BC Impacts on history: Dependable year-round food supply enables division of labor and specialization that spurs invention. Artifacts: Spinning/weaving tools, stone plows, sickles © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

10. The Neolithic Age Examples of Engineering Design during the Neolithic Age: Mesopotamian engineers used clay tablets to document irrigation systems. Babylonian engineers used mathematical concepts such as algebra for land excavation calculations. Egyptian engineers built the pyramids. © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

11. The Bronze Age The architectural period that included combining copper and tin to produce bronze Time Period: 2,300 BC – 700 BC Impacts on history: The use of bronze replaced stone tools and allowed humans to greatly alter their environment. Artifacts: Bronze jewelry, tools/weapons © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

12. The Iron Age The architectural period marked by the prevalent use of iron or steel Time Period: 700 BC – 450 AD Impacts on history: Military dominance for cultures that could produce iron weapons. The iron-blade plow allowed humans to increase food production. Artifacts: Iron farming equipment/weapons, manuscripts © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

13. The Iron Age Examples of Engineering Design during the Iron Age: Greek engineers created the crossbow and catapult to conquer territories. Roman engineers created aqueduct systems, sanitary systems, and an extensive road system. © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

14. The Middle Ages The architectural period after the Roman Empire. Divided into Early Middle Ages, High Middle Ages, and Late Middle Ages. Time Period: 450 AD – 1,400 AD © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

15. The Middle Ages Impacts on history: In the late Middle Ages: famine, plague and war, often marked by the Black Death, which killed approximately one-third of the population Artifacts: Improved harness for horses, cast iron, cannons, mechanical clocks, compass, printing press. © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

16. The Renaissance / Enlightenment The architectural period marked by the revival of classical influence and the sharing of ideas, or in Italian (Rinascimento – “to be reborn”) Time Period: 1,400 AD – 1,750 AD Impacts on history: Instrumentation enabled scientists to observe and quantify natural phenomena. Artifacts: Telescope, microscope, thermometer © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

17. The Renaissance / Enlightenment Examples of Engineering Design during the Renaissance: Leonardo da Vinci was born in Italy in 1452 and began his career as an artist, painting and sculpting. He also designed weapons, buildings, and machinery. © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology
