• METHODS OF PORTRAYING SCALE ON A MAP:
• Graphic Scale = scale bar
• Verbal Scale = written statement
• Fractional Scale = representative fraction

What kind of scale?

“One inch to 5 miles”

Verbal scale

What kind of scale?

1:316,800 or 1/316,800

Fractional Scale

What kind of scale?

Graphic Scale

These mushroom spores are too small to see, so we put them under a MICROSCOPE.

When we can see them, we can study them.

This planet is too big to see,

so we put it under a MACROSCOPE.

When we can see it, we can study it.

Scale is Critical to Critical Thinking
• Using reason to decide what to believe
• Helps you assess the authenticity and accuracy of information
• Helps you apply careful, precise, persistent and objective analysis of any knowledge claim or belief to judge its validity.

ETHNIC CONFLICT AND THE CONCEPT OF SCALE

• Ethnic conflicts abound on the world political map. To understand them, we use a set of concepts:
• minorities
• majorities

What is a minority?

“the smaller in number of two groups constituting a whole”

- Merriam-Webster OnLine

Somali 60%

Afar 35%

• Tibet 3 million Buddhists
• Myanmar 50 million Buddhists

• China Buddhist?
Pattern Probing Using Scale
• If we are close,

Then, we see lots of detail, but may not recognize overall patterns.

• If we are far away,

Then we miss lots of detail, but recognize overall patterns.

How does the use of a “macroscope” change your view of the following islands?

● Ireland:

Who’s the minority? Catholics or Protestants?

● Cyprus:

Who’s the minority? Greeks or Turks?

● Timor:

Who’s the minority? Muslims or Christians?
