Create a simple "Where I Found My Facts" source list crediting each source used, in a consistent, simplified format.
When you use someone else's research to write your own report, you give them credit by CITING your sources -- telling the reader exactly where each fact came from. This is not just a rule; it lets a curious reader go check your facts or learn even more.
You do not need a complicated grown-up citation format. A simple "Where I Found My Facts" list works great: the title of the book or website, and the author's name if you know it.
Mastery looks like: They create a correctly formatted, simple source list crediting every source used in the report.
Common stumbles: Forgetting to cite a source they actually used, or citing a source so vaguely ("a book") that no one could find it again.
