Take notes from at least two different sources, in their own words, organized by research question, with the source noted for each card.
Now the real research begins. You will find at least TWO different sources -- books, reliable websites, or encyclopedia articles -- and take notes on note cards, one fact per card. Using more than one source helps you check facts and find more detail than one book alone could give.
Write notes in YOUR OWN WORDS, not copied word-for-word from the source. On each card, jot which research question it answers and which source it came from -- that second part matters even more later, in the citations lesson.
Mastery looks like: They take multiple note cards from at least two sources, each in their own words and tagged with its question and source.
Common stumbles: Copying sentences word-for-word from a source instead of putting the fact into their own words.
