When did engineering begin? Who were the first engineers? What were the first engineering designs? 3

Word engineering comes from “ingenuity” • It has been pretty well agreed that the words 'ingenuity' and 'engineering' in English and 'ingéniosité' and 'ingénierie' in French are linked to the same Latin word-root and that the verb 'to engineer' means 'to be ingenious. ' So the kinds of things engineers have done have been generally ingenious. And the word 'engine' means 'an ingenious and useful device. ' 4

Introduction In prehistoric times, men and women had to be ingenious in order to survive hunger, enemies, climate and, later, the tyranny of distance. So there have always been 'engineers' around, many of whom were involved in activities we would not associate with engineering today. They were rather involved in hunting, farming, fishing, fighting, implement- and tool-making, transportation and many other things. 5

The Beginnings of Engineering: 6000 - 3000 B. C. in Asia Minor 6

Let’s Travel Through Time • • • 1200 BC – AD 1 – 1000 – 1400 – 1700 – 1800 – 1875 – 1925 – 1950 – 1975 – 1990 -- 2000 12

In Class Hands On Activity • Teams of 6 • Each team the list of engineering inventions • As a group, put each invention in the correct time period. That is, put a sticky with the time period number next to each invention. Put the sheets on the wall with your numbers. • When we get the answers, if yours is wrong, have a representative remove the sticky. The team with the most correct answers at the end of class wins. 13

In Class Hands On Activity • Team representatives – place each sticky note on the wall under the time period you think the activity belongs • You have “two minutes to win it” and place all your sticky notes • Ready! Set! GO! 14
