What is Technology?

What is Technology?

• Technology is all around you. It has always been
  a part of your daily life. Yet could you define
  technology? Before I tell you what technology
  means, take out a sheet of loose-leaf and write a
  paragraph What you think technology is? (To be
  passed in with your name on it.)

Technology is

• Processes and knowledge that people use to extend
  human abilities and to satisfy human needs and
  wants. In other words, people create technology
  to solve problems and to make it possible to do
  new things. When people needed a way to keep food
  cold, they invented refrigerators.
• On your paper write of a need that humanity
  created a technology for.

The History of Technology
6
The Stone Age

• Early humans
• 2 million years ago to about 4000 BC
• Went from basic chipped stone tools, needles and
  harpoons, finally to highly polished items.
• The birth of agriculture

7
 The Bronze Age

• Human culture begins
• Most weapons and tools were made of bronze
  (copper mixed with tin). 
• Melts at a low temperature so its easy to work
  with.
• Ended around 1200 BC

8
The Iron Age

• Period of development of modern technology
• Iron replaces bronze (smashes it to smithereens
  in any sword fight)
• Furnaces were built to reach the high melting
  point of the metal
• Took place about 500 BCTime roads were built,
  aqueducts were used, and finally the birth of
  public sewers.

9
Industrial Revolution

• The age of super growth with innovations in
  technology
• 1750 to 1830s
• the earth starts to die (well actually, the
  increase in the number of factories made the
  amount of greenhouse gases shoot through the roof)

10
The 20th Century

• The number of innovations are countless.  The
  human race is a technological superpower, well,
  to us anyway.
