What is the best tool to create your magazine article? That is up to you. You may use Google Docs, Google Slides, or even Canva. If you would like to start with the Biography Doc Template, make a copy for yourself. If you are starting from scratch, use page settings to create an article that fits on paper that is 8 1/2 x 14".
Start with the Database Tab and evaluate the sources that will work best for this project. Britannica, WorldBook, and Biography are great places to start. Additionally, some biographies exist in Sora, Epic, and the library Catalog.
