Unit 2: The engineering process; Lesson 1: What is the design process?

  1. 1. Unit 2 Lesson 1 What Is the Design Process? Copyright © Houghton Mifflin Harcourt Publishing Company
  2. 2. Unit 2 Lesson 1 What Is the Design Process? Works of Ingenuity • Computers and other engineered devices help us solve many problems. • Engineers use computers and hand-drawn diagrams to plan designs. • People use products of engineering every day, such as toothbrushes, faucets, cars, and buses. Copyright © Houghton Mifflin Harcourt Publishing Company
  3. 3. Unit 2 Lesson 1 What Is the Design Process? Works of Ingenuity • Engineers are problem solvers who invent or improve products that help us meet our needs. • Engineering is the process of using science and mathematics to find solutions to everyday problems. • Engineers work in many fields. They can design and test materials, work in factories or on farms, or work in medical laboratories. Copyright © Houghton Mifflin Harcourt Publishing Company
  4. 4. Unit 2 Lesson 1 What Is the Design Process? The Right Tool for the Right Job • Technology is any device that people use to meet their needs and solve practical problems. • Technologies such as tools and machines, medicines, and even weather satellites play an important role in improving lives. Copyright © Houghton Mifflin Harcourt Publishing Company
  5. 5. Unit 2 Lesson 1 What Is the Design Process? The Right Tool for the Right Job • Technology changes as people’s knowledge increases and they find better ways to meet their needs. • For example, over the past 150 years electric washing machines have replaced washboards and hand-cranked washing machines. Copyright © Houghton Mifflin Harcourt Publishing Company
  6. 6. Unit 2 Lesson 1 What Is the Design Process? The Design Process (Part 1) • Engineers follow a design process to design new technologies. The process includes a series of steps. • Engineers identify a need, or problem, and then brainstorm possible solutions. • Engineers also choose the most practical solution and build a working model, or prototype, to test. Copyright © Houghton Mifflin Harcourt Publishing Company
  7. 7. Unit 2 Lesson 1 What Is the Design Process? The Design Process (Part 1) • Engineers keep careful records, such as detailed notes and drawings, throughout the design process. • These records help engineers remember what they have done and provide information to others working on similar problems. Copyright © Houghton Mifflin Harcourt Publishing Company
  8. 8. Unit 2 Lesson 1 What Is the Design Process? The Design Process (Part 1) • These detailed records are also used to build and make changes to the prototype. • If the prototype doesn’t work, the records help the engineer determine what might work next time. Copyright © Houghton Mifflin Harcourt Publishing Company
  9. 9. Unit 2 Lesson 1 What Is the Design Process? The Design Process (Part 2) • Engineers test and improve the prototype based on criteria, or standards that determine how well the design is doing its job. • They also redesign and modify the design if it does not meet all criteria or is unsafe. • Engineers then communicate the design results orally and in written reports.

  10. 10. Unit 2 Lesson 1 What Is the Design Process? If At First You Don’t Succeed... • Materials, cost, production time, and safety are some of the criteria that engineers consider when designing products. • Thomas Edison tried a thousand times and took two years to develop a longer-lasting light bulb. • Finding materials that work well affects the design process. When designing the light bulb, Edison had to find materials that can handle heat. Copyright © Houghton Mifflin Harcourt Publishing Company
  11. 11. Unit 2 Lesson 1 What Is the Design Process? If At First You Don’t Succeed... • Some technologies are costly to develop. The high cost of building prototypes can affect the cost of the final product. • Some products, such as cars, can take years to develop because they must undergo safety and environmental testing.
