Did you know you're a historian? When you talk about the events in your life, you are creating a chronology! Historians use chronologies, or timelines, to understand events. Learn to make your own!

Lesson Plan - Get It!


Who are you? It's one of the most important questions in life. Everyone will answer it differently, each according to the experiences they have had in the past. The sequence of the events of your life makes up a big part of who you are today. That sequence of events is called chronology.

Think about the major events of your life.

Jot down the five or six most important ones. Now, go back and look at your list. If you're like most people, you probably wrote them in order, from earliest to latest. Why does putting things in sequence make so much sense?

Historians spend a great deal of time thinking about sequences of events.

Knowing how one event led to another can tell us a lot about the world. Historians strive to create a chronology that explains later events and conditions, and they can represent that chronology in a variety of ways.

Read Chronology, from Writing on History by the Queens College History Department.

As you read, take notes on important points and answer these questions:

  • What is a good definition of chronology?
  • Why do historians use chronology?
  • How do historians show chronology?

Now reflect and write:

  • How many different ways can you visually show chronology?
  • Share your thoughts and ideas with a parent or teacher, and seek their ideas.

Next, continue on to the Got It? section to research some timelines.
