Technological
Development
Technology keeps changing. It is often the
result of a series of refinements to an idea
or basic invention.
Civilization has changed because of 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 people learning from each other.
Today, technological development is based
on scientific knowledge and engineering
design.

The Paleolithic Age
The Old Stone Age or in Greek (palaios – “old”)
and (lithos – “stone”)
Time Period: 500,000 BC – 10,000 BC
Impacts on history:

The Mesolithic Age
The Middle Stone Age or in Greek (mesos –
“middle”) and (lithos – “stone”)
Time Period: 10,000 BC – 4,000 BC
Impacts on history:
The gradual domestication of animals
and agriculture led to settled
communities.

The Neolithic Age
The New Stone Age or in Greek (néos – “new”)
and (líthos – “stone”)
Time Period: 4,000 BC – 2,300 BC
Impacts on history:
Dependable year-round food supply
enables division of labor and
specialization that spurs invention.

The Bronze Age
The architectural period that included
combining copper and tin to produce bronze
Time Period: 2,300 BC – 700 BC
Impacts on history:
The use of bronze replaced stone tools
and allowed humans to greatly alter
their environment.
Artifacts:
Bronze jewelry, tools/weapons

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, plaque 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:
Arab society developed paper
and chemistry applications.
Chinese society developed
clocks, gunpowder, and
astronomical instruments.
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:
