2. Design & Engineering

3. What is Technology? n List the 5 things that come to mind when you think of “technology”

4. What is Technology? n Is there a difference between computer literate and technologically literate? n i.e. does technology require computers?

5. What is Technology? n List the 5 things that come to mind when you think of “technology”

6. Technology… takes place when people use their knowledge and creativity to extend their abilities, satisfy needs and wants, and solve problems

7. What is Technology? n The practical use of human knowledge to extend abilities, satisfy needs and wants, and to solve problems

8. Pgs 22-41 n Technology n Nanotechnology n Design n Invention n Innovation n Criteria n Constraint n Brainstorming n Prototype n Engineer n Productivity Unit 2 Vocabulary

9. Unit 2 Review n Page 41 n Read & Respond #1-10 n Think & Apply #1,4

10. The Development of Technology n Nomadic era - Hunting and gathering n Agricultural age – plow and sickle n Development of villages where there was farming and raising livestock n 1700’s = Industrial Age n Muscle power was replaced with machine power of the steam engine n Transportation systems originated n Today = Information age n Began in the mid 1800’s n Development of transistor and computer

11. The Design Process n Are you an inventor? n Are you innovative? n Design is the process of making new things by planning

12. Invention n Improving and changing a technology that already exists n The process of designing new products Innovation

13. The Design Process n Much like the scientific method n However you may skip around from step to step http://www.doe.mass.edu/frameworks/scitech/2001/standards/strand4.html

14. The Design Process 1. Identify a Need or Define the 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

15. Identify a Need or Define the Problem n Criteria – Things that the product must do or include n Constraints – Limits placed on the design and the designer

16. Gather Information n “No need to reinvent the wheel’ n Research, visit, internet search, talk to people, etc.

17. Develop Possible Solutions n Think of as many design ideas as possible n “Brainstorm” Brainstorming n Process in which group members suggest ideas out loud as they think of them n Ideas are usually written down on a board in front of the group n All advantages and disadvantages of each idea is discussed

18. Model the Solution n Two dimensional and pictorial drawings/sketches n Scale models n Appearance models n Functional models n Prototype n Computer Simulation

19. Test and Evaluate the Solution n Does it do what it is supposed to? n Is it safe to use? n Will it last as long as it needs to? n Is the cost within acceptable limits? n Is it comfortable to use? n Does it have a pleasing appearance? n Does it stay within the criteria and constraints?

20. Refine the Solution n If changes are needed after testing and evaluations you may improve your solution

21. Communicate your Ideas n Designers have to prove their ideas are worthy of manufacturing n Drawings, charts, prototypes, and dialogue are necessary

22. Who Designs Solutions Engineer n Person who uses his or her knowledge of science, math, technology, and communication to solve technical design problems

23. A New Generation of Engineering n Manufacturing Engineers u Increase productivity n Aerospace Engineers u Aircrafts n Materials Engineers u Develop products for strength, weight, etc n Environmental Engineers u Design cleaner production methods n Computer Engineers u Hardware and software designs

24. Interactive CD Activity n Visit the “Designed World” Interactive Lab on the Student CD to explore more about some of the technologies in our lives.

25. Nanotechnology

26. n An engineering field that involves manipulating materials on an atomic or molecular level

27. Principles and Elements of Design n “The Elements of Design” and “The Principles of Design” on the Student CD

28. Unit 2 Project n Investigate the work of a famous designer, inventor, or engineer. n Prepare a PowerPoint presentation showing that person’s accomplishments
