OBJECTIVES

• Explain how science, technology, and engineering
  are related.
• Identify ways that technology responds to social
  needs.
• Explain the engineering design process for
  developing new technologies.
• Describe technology in terms of its intended
  benefits and unintended consequences.

State Performance Indicators
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 (e.g., food, biofuels,
medicines, integrated pest management).
12
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.

13
Telephones have changed over the years, becoming
smaller and more mobile.
14
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.
15
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.
16
A real life transformer
Flat materials and origami patterns, a real life
transformer (self-folding robot) has the
potential to get into tight spaces for search and
rescue missions, like in rooms with collapsed
buildings.
17
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.

18

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

19

• 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.

20
Wireless electricity Energy harvesting
Engineers are cutting the cords on electricity.
These two new technologies will free us from the
tangle of cords and plugs. Energy harvesting taps
into energy that is already moving through our
environment. It grabs radio waves and microwaves
and turns in to electricity!
21

• 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.

22
Googles prototype self-driving
23

• 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.

24

• Step 5 Improve Modifying and 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.

25
Five steps in the engineering design process
26
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.
27
Technology and Society
Technology provides solutions for many types of
social, and economic needs. Intended Benefit
An intended benefit is the positive purpose for
which a technology is designed to be used.
Cell phones allow people to stay connected with
others and to call for help....
28
Unintended Consequences are uses or results
that engineers do not purposely include in the
design of products. An unintended consequence can
be beneficial.
These towers have been disguised as trees to
minimize their detracting from landscape
29
Bioengineering
The application of engineering to living things,
such as humans and plants, is called
bioengineering.
30

• Bioengineered technologies can be classified as
  either assistive or adaptive.
• Assistive technologies are developed to help
  organisms without changing them.

Boys gets prosthetic hand made by 3-D printer
31

• Adaptive bioengineered products change the living
  organism.

Prosthetic heart is an artificial organ that is
permanently Implanted inside the human body
32
Assistive or Adaptive?
The Amazing Spiderman!
33
Exit Ticket
Which of the following is an unintended
consequence of the cell phone? A cell phone
rings can interrupt others B people can take
phones in cars to communicate in emergencies C
business people can keep in better touch with
their customers D long-distance calling can
be more affordable
