Kid-friendly explanation

A secondary source is like a story someone tells about something that already happened. The person was not there, but they used other information to explain it. A textbook chapter, a history video, or a website that talks about the past are all secondary sources. They help you understand what happened and why.

Worked examples

Example 1 (younger students):

Imagine a big snowstorm happened at your school last year. Your teacher shows your class:

  • A photo taken during the snowstorm.
  • A page from this year's textbook that tells the story of the snowstorm.

The photo is a primary source, because it was made during the snowstorm. The textbook page is a secondary source, because someone later used photos, notes, and memories to write about the snowstorm and explain it.

Example 2 (older students):

A historian, which is a person who studies and writes about the past, wants to understand life in a city during the 1920s. They look at:

  • Old newspapers from the 1920s.
  • Letters people wrote in the 1920s.
  • Modern history articles and a recent book about the 1920s city.

The newspapers and letters from the 1920s are primary sources, because they were created at the time. The modern articles and the recent book are secondary sources, because the authors used those older materials to analyze and explain what life was like in that city.

Going deeper

As students move into middle and high school, secondary sources become a key part of research. Textbooks, documentaries, and scholarly articles help your child see how different historians have interpreted the same events in different ways.

Secondary sources are also important for understanding historical context. They often pull together many details about a time period, such as laws, technology, and everyday life, to explain why people acted as they did.

Older students are often asked to compare multiple secondary sources, notice where authors agree or disagree, and decide which explanations are best supported by evidence from primary sources and from physical objects called artifacts.

Common mistakes

  • Mistake: Thinking anything "old" is a primary source and anything "new" is a secondary source.
    Correction: The difference is not about age, but about purpose. A primary source is created during the event, while a secondary source is created later to interpret or explain that event.
  • Mistake: Believing secondary sources are always less useful than primary sources.
    Correction: Secondary sources can be very valuable, because they organize many primary sources, add background information, and show how experts understand the past.
  • Mistake: Assuming a source can only ever be primary or secondary, never both.
    Correction: The same item can be a primary source in one study and a secondary source in another, depending on the question being asked and how the source is being used.

Everyday connection

Secondary sources show up in daily life whenever someone explains something that already happened. A news article that looks back on last year's championship game, a video that explains how a famous leader changed history, or a museum sign that describes an object are all secondary sources your child might see.
