Chronological (Temporal) Pattern

In a chronological (temporal) pattern, you present the information in time-based sequence, from beginning to end. Each main point covers a particular point in the chronology. If you are discussing a subject that follows a sequence, such as a historical event or a process, this pattern can help your audience keep track of what you are saying. For instance, a speech discussing the decline and rebound of bald eagles in the lower forty-eight states could use a chronological pattern:

  1. In 1963, the bald eagle had nearly disappeared from the lower forty-eight states.

  2. In 1972, the harmful pesticide DDT was banned in the United States.

  3. During the next twenty years, governments and individual citizens took steps to protect bald eagles.

  4. In 2007, bald eagles were taken off the list of endangered species.
