1. Tech 84 Mr. Graves DESIGN and ENGINEERING

2. Vocabulary Technology Nanotechnology Design Invention Criteria Constraint Brainstorming Prototype Engineer Productivity

3. Unit Objectives 1.Define technology. 2.Connect technology and human needs and wants. 3.Identify steps of engineering process. 4.Describe role of engineers and designers and problem solvers.

4. What is Technology? People using their knowledge to: – Extend their abilities – Satisfy their needs and wants – Solve problems

5. Space and Medicine International Space StationDa Vinci Surgical System

6. Military

7. Nanotechnology Manipulating materials on an atomic or molecular level Produced machines smaller than 1/1000 of the diameter of a human hair Didn’t happen overnight, though

8. Why the Development of Technology? Lives become more complex So do needs and wants Human need to makes life better and easier

9. Ages of Technology Agricultural Industrial Information

10. Agricultural Age Began 10,000 years ago Based on growing crops and raising livestock Plow, loom, reading and writing, measurement, money Growth of towns and cities Specialization People worked where they lived

11. Industrial Age Began about 1750 Based upon manufacturing Steam engine, blast furnace, mass production, train, plane, automobile, skyscraper Public Schools Farms to cities Greater productivity People travel to work

13. Information Age Began around 1850 Based on knowledge Telephone, radio, TV, transistor, computer, internet Electronic business, Electronic education, Globalization, Work goes with you… home or on the road

15. The Design Process Agricultural to Technological age progression due to design Design is the process of creating things by planning. The process of designing new products is called invention. Improving or changing technology that already exists is called innovation.

16. The Design Process 1.Identify a Need or Define a Problem 2.Gather Information 3.Develop Possible Solutions 4.Model the Solution 5.Test and Evaluate the Solution 6.Refine the Solution 7.Communicate Your Ideas

17. Identify the Need or Problem Some are simple to id and others quite complicated Criteria – Things that a design must do or include Constraints – Limits placed on the design and designer
