Title: Chapter 1 Technology

Chapter 1 Technology Science

  • State Performance Indicator
  • ?SPI 0807.T/E.2-Evaluate a protocol to determine
    if the engineering design process was
    successfully applied.
  • ?SPI 0807.T/E.3-Distinguish between the intended
    benefits and the unintended consequences of a new
    technology.
  • ?SPI 0807.T/E.4-Differentiate between adaptive
    and assistive engineered products (Ex food,
    biofuels, medicines, integrated pest management).

3
What Is Technology?
  • ?Technology refers to the products and processes
    that are designed to serve our needs.
  • Technology also refers to the tools and methods
    for creating these products.
  • Technology applies to any product, process, or
    knowledge that is developed to meet a need.

4
  • Engineering is the process of creating
    technology.
  • Scientists, inventors, business owners, artists,
    and even students have also engineered new
    technologies.
  • Anyone can follow the engineering design process
    to solve a problem or address a need.

5
How Does Science Relate to Technology?
  • Engineering uses scientific knowledge to develop
    technologies.
  • Engineers use science and mathematics to create
    new technologies that serve human needs.
  • There are many different types of engineers who
    develop a variety of very different products.

6
What is the Engineering Design Process?
  • The engineering design process has similarities
    to the scientific process.
  • Like the scientific process, some steps may
    require repeating or modifying to fit different
    needs.

7
Step 1 Ask Identifying Researching a Need
  • Engineers define and describe the need or problem
    they are trying to solve.
  • Research provides engineers with information for
    problem solving.

8
Step 2 Imagine Developing Possible Solutions
  • Brainstorming is the process in which a group of
    people share ideas quickly to promote additional
    ideas.
  • Sometimes a possible solution to the problem
    comes from these ideas or it may take more time
    and thought.

9
Step 3 Plan Making a prototype
  • A prototype is a test model of the product.
  • Prototypes allow engineers to see if their design
    works the way they expect it to.

10
Step 4 Create Testing and Evaluating
  • Prototypes are tested and evaluated.
  • Engineers complete a cost-benefit analysis to
    make sure that the cost of designing and
    producing the new product is worth its benefit.

11
Step 5 Improve Modifying Retesting the Solution
  • If a prototype was not successful or did not work
    well, engineers would either modify their
    prototype or try a new solution.
  • It is important that the engineers consider what
    was learned from the first prototype before they
    begin the design process again.

12
Step 6 Communication
  • Engineers often need to share their successes,
    failures, and reasoning with others.
  • Engineers may explain and promote the technology
    to customers, or they may communicate with the
    public through news releases, advertisements, or
    journals.

Technology and Society
  • Technology provides solutions for many types of
    social, political, and economic needs.
  • Intended Benefit- An intended benefit is the
    positive purpose for which a technology is
    designed to be used.
  • Unintended Consequences- Unintended consequences
    are uses or results that engineers do not
    purposely include in the design of products. An
    unintended consequence can be beneficial.

15
What is Bioengineering?
  • The application of engineering to living things,
    such as humans and plants, is called
    bioengineering.
  • Bioengineered technologies can be classified as
    either assistive or adaptive.

16
  • Assistive technologies are developed to help
    organisms without changing them. Such as glasses,
    contacts, crutches, wheel chair, cane, hearing
    aid
  • Adaptive bioengineered products change the
    living organism. Such as cochlear implant, pace
    maker, organ transplant, bioengineered products
