Thresholds/PeriodizationsWhat is a thresholds or periodization:

The way history is divided into discrete and definable periods.

For example: Neolithic Revolution or Industrial Revolution

These periods are marked by turning points, or dates when a number of

important and long lasting changes can be identified for the largest number of

people.

There are competing models of periodization.

Some turning points may be more import to some regions or cultures of the world

than another.

If the length of the room represented :13.7 Billion years how ‘significant’ is our modern era in relation to the rest of the

world’s history?

1 inch = 40.8 million years (scale 1)

1 foot= 2.04 billion years (scale 2)

Place each threshold or period at the appropriate place on the line.

Be prepared to defend why you placed it where you did.
