Title: Introduction to Engineering and Technology Concepts


1
Introduction to Engineering and Technology
Concepts
  • Unit One
  • Chapter One What is Technology?

2
Instructions for Success
  • Each chapter of every unit will begin with a
    Mindjog. This is a warm up question that you
    should answer in your workbook in the proper
    chapter.
  • Please take notes as you move through the
    presentations in the notebook that has been
    provided.
  • Sections will come up in each presentation with
    an assignment notice. Turn to the section
    detailed on the slide in your workbook and
    complete the assignment before proceeding.
  • Good luck!

3
Objective
  • Students will generate definitions for the term
    technology and will develop an understanding of
    the nature of technology.

4
Mindjog!
  • On your worksheet, please respond to the
    following question 
  • In your own words, please define the term
    technology.

5
Definition of Technology
  • Consider what you wrote for the Mindjogs
    answer. Now, have a look at the accepted
    definition of technology
  • Technology humans using objects to change the
    natural and manmade environment (Wright, 2004) .

6
The Subject of Technology
  • It is important to note that technology has heavy
    roots in natural scientific laws, such as
    gravity.
  • That technology developed in one area of the
    world and/or point in time was developed because
    of that groups needs and wants.
  • If that technology is transferred to another
    group, it can change the culture, society,
    economics, and politics of said group.
  • That technology will go through constant
    evolutions, but that earlier technology was based
    on technological know-how, not science itselfas
    we will see in this first Chapter (Wright, 2004).

7
Think about this
  • Some people consider technology to be computers
    and other high-end products.
  • In truth, technology can be anything from the pen
    in your hand to the computer you are working on.
  • All technology has FOUR basic features (Wright,
    2004) .

8
Four Features of Technology
  • Technology is human knowledge.
  • Technology uses tools, materials, and systems.
  • Any application of technology results in
    artifacts and other outputs.
  • Technology is developed by people to modify or
    control the environment (Wright, 2004).

9
Other Outputs?
  • On the last slide, it was stated that one of the
    features of technology is the result of other
    outputs.
  • What does this mean?
  • First, if artifacts are human-made things, then
    the other outputs are the leftovers.
  • These outputs can include things like pollution
    and scrap (Wright, 2004).

10
Dynamics!
  • Think about a piece of technology that has
    changed dramatically over the years.
  • Consider video gamesthey used to be basic dots
    and squares with beeps and noises now they are
    interactive three dimensional worlds with special
    effects and orchestrated music.
  • What does this mean?

11
Dynamics (continued)!
  • It means that technology is constantly changing
    and evolving.
  • This means that technology, by nature, is a
    dynamic process.
  • Technology is changing and it also causes change
    (Wright, 2004).

12
Assignment 1
  • Please turn to the section in your workbook
    entitled, Unit 1, Chapter One What is
    Technology?
  • Complete the extension questions under the
    Assignment 1 header before moving onto the
    next section of slides.

13
BEFORE MOVING ON
  • Did you complete the Assignment 1 Section
    under the Unit 1, Chapter One What is
    Technology section of your workbook?
  • If you have, please proceed to the next slide.

14
Technologys Evolution
  • We have already established that technology is
    dynamic.
  • The earliest piece of technology has been around
    as long as humanity has walked this Earth 2.5
    million years ago! (Wright, 2004).
  • Can you guess what it is?
  • The first piece of technology was A ROCK!

15
Technologys Evolution (continued)
  • How is a rock a piece of technology?
  • While not manmade, a rock makes our life easier.
  • Technology can also be defined as anything that
    makes a humans life easier.
  • Our decedents used this early technology for
    cutting and pounding (Wright, 2004).

16
The Timeline
  • The evolution of technology can be divided up
    into seven ages. They are
  • The Stone Age
  • The Bronze Age
  • The Iron Age
  • The Middle Ages
  • Renaissance
  • The Industrial Revolution
  • The Information Age (Wright, 2004).

17
The Stone Age
  • The earliest period of technology occurred
    between 1,000,000 and 3,000 B.C.
  • Important technologies used and invented during
    this time include stone tools, cave paintings,
    pottery, and fire (Wright, 2004).
  • Populations became more productive, meaning that
    more people could live in a given area (Wright,
    2004).

18
The Bronze Age
  • The bronze age lasted 3000 1200 B.C.
  • As populations grew, new technology was needed to
    support the masses.
  • Copper was discovered, melted down with other
    ores to produce the strong metal known as bronze.
  • Technologies invented include copper and bronze
    tools, smelting, frescoes, writing, paper, ink,
    and irrigation systems for agriculture (Wright,
    2004).

19
The Iron Age
  • The Iron Age began in 1200 B.C. and ended in 1300
    A.D.
  • Iron and steel became the primary source for
    creating technology, due to its lower cost in
    comparison to copper and bronze.
  • The iron age saw the development of iron tools,
    furnaces, aqueducts, body armor, ox-drawn plows,
    spinning wheel, windmill, the alphabet, and coins
    (Wright, 2004).

20
The Middle Ages
  • The Middle Ages lasted from 500 1500 A.D.
  • The Middle Ages saw the advent of the printing
    press, magnetic compass, paper money, and
    waterwheel (Wright, 2004).

21
The Renaissance Age
  • The Renaissance lasted from 1300 1600 A.D.
  • This period is known for being a time for
    advancements in art, literature, history, and
    other socio-cultural subjects.
  • Technologies included the telescope, hydraulic
    press, and the calculating machine (Wright,
    2004).

22
Industrial Revolution (continued)
  • The revolution excelled due to the process of
    manufacturing
  • Manufacturing sees longer lasting machines due to
    the use of interchangeable parts.
  • Jobs are divided to different workers.
  • Machines now bring work to the workers.
  • The emergence of management.
  • (Wright, 2004)

23
The Information Age
  • The Information Age is happening all around us.
  • The technologies include the desktop computer,
    robots, solar energy, cell research, satellites,
    and lasers.
  • (Wright, 2004)

24
Information Age (continued)
  • This period has several characteristics
  • Wide use of automated machines and
    information-processing equipment.
  • High demand for trained positions.
  • The line between management and workers becomes
    blurred.
  • There is constant, job-related training for
    improving and keeping workers.
  • (Wright, 2004)

25
What Age is Next?!
  • Be assured that our current technologies will be
    improved upon.
  • This will bring about a whole new age!

26
