When doing your research, you will need to use both primary and secondary sources to get information.
A primary source is information from someone who was there when something happened. It is direct, first hand evidence. A secondary source is information that was created later, from someone who wasn't there when it happened.
For example, if I saw a robbery, and I talked about it, I'm a primary source, because I was there. If I tell my friend, my friend becomes a secondary source - they know information, but they weren't there. They didn't see it.
Even if something happened a long time ago, we can still use primary sources like old diaries, speeches people gave in the past, or their notes from long ago.
When you read/watch/ listen to a source of information, make sure you take notes. You can use this template to help keep notes and record the websites you visit.
