 The BIG Idea
Big Idea:

People are better able to understand the world

around them when they explore how people of
all times and places have used their unique
skills to develop inventions and innovations.

 Technological
Development
Technology is evolutionary and is often
the result of a series of refinements to an
idea or basic invention.

The evolution of civilization has been

directly attributed to the development of
tools and materials.

 Technological
Development
The impact of technological development
can be divided into four categories:
Social the impact on people
Political the impact on policy and laws
Cultural the impact on human achievement
Economic the impact on the economy

 The History of Technology
Early in the history of technology, the
development of tools and materials was
based on technological know-how.

Today, technological development is based

on scientific knowledge and engineering
design.

 The History of Technology
The History of Technology can be divided
into nine distinct periods of time:
Paleolithic Age The Middle Ages
Mesolithic Age The Renaissance
Neolithic Age Industrial Age
Bronze Age The Information
Iron Age Age

mathematical concepts such as
algebra for land excavation
calculations.
Egyptian engineers built
the pyramids.

 The Iron Age
The architectural period marked by
the prevalent use of iron or steel
Time Period: 700 BC 450 AD
Impacts on history:
Military dominance for cultures that
could produce iron weapons.
The iron-blade plow allowed humans to increase food
production.
Artifacts:
Iron farming equipment/weapons, manuscripts

 The Iron Age
Examples of Engineering Design during the Iron
Age:
Greek engineers created the
crossbow and catapult to
conquer territories.
Roman engineers created
aqueduct systems, sanitary
systems, and an extensive
road system.

 The Middle Ages
The architectural period after the Roman
Empire. Divided into Early Middle Ages, High
Middle Ages, and Late Middle Ages.
Time Period: 450 AD 1,400 AD
Impacts on history:
Early Middle Ages increased
pressure from invasion lead to
depopulation and deurbanization.

 The Middle Ages
Impacts on history:
High Middle Ages the beginning of feudalism,
population increase, and agricultural innovation
Late Middle Ages famine, plague and war,
often marked by the Black Death,
which killed approximately one-third
of the population
Artifacts:
Improved harness for horses, cast iron,
cannons, mechanical clocks, compass

 The Middle Ages
Examples of Engineering Design during the
Middle Ages:
Technology, like the windmill,
produced mechanical labor.
The printing press was used
to share information and
knowledge.
The word engineer began to
appear as ingeniare or to
design or devise.

 The Renaissance /
Enlightenment
The architectural period marked by the revival
of classical influence and the sharing of ideas,
or in Italian (Rinascimento to be reborn)
Time Period: 1,400 AD 1,750 AD
Impacts on history:
Instrumentation enabled scientists to
observe and quantify natural phenomena.
Artifacts:
