1. Introduction to the
GeoHistoGram

2. Objectives: Students will be able to:
Identify the elements of the GeoHistoGram
Explain how the GeoHistoGram organizes knowledge
Identify historical eras and major events in each

3. This is the basic form
of the GeoHistoGram –
seven vertical bars.

4. The GeoHistoGram has no definite beginning date.
Time goes up the side,
from the distant past on the bottom to the present at the top.
The GeoHistoGram has no definite beginning date.
The time before Era 1 is labeled Pre-history.
Time goes up the side,
from the distant past on the bottom to the present at the top.

5. from the Americas in the west to Polynesia in the east
The bars represent
major world regions,
from the Americas in the west
to Polynesia in the east
Space goes across the diagram,
from west on the left
to east on the right.

6. Eras on the GeoHistoGram
Mark the Eras on the GeoHistoGram (through Era 7)
Label with title of Era
