Transcript 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.
Technology
Technology is a word with origins in the
Greek word technologia (τεχνολογία), techne
(τέχνη) "craft" and logia (λογία) "saying." It is
a broad term dealing with the use and
knowledge of humanity's tools and crafts.
The Six Areas of Technology
• Communication
• Energy and Power
• Manufacturing
• Construction
• Transportation
• Bio-related Technology
On your paper give an example of each.
The History of Technology
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
The Bronze Age
• Human culture begins
• Most weapons and tools were made of
bronze (copper mixed with tin).
• Melts at a low temperature so it’s easy
to work with.
• Ended around 1200 BC
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.
Industrial Revolution
• The age of super growth with
innovations in technology
• 1750 to 1830’s
• the earth starts to die (well actually, the
increase in the number of factories
made the amount of greenhouse gases
shoot through the roof)
The 20th Century
• The number of innovations are
countless. The human race is a
technological superpower, well, to us
anyway.
