Also known as CD, specific details that form the backbone or core of your body paragraphs. Synonyms for concrete details include facts, specifics, examples, descriptions, illustrations, support, proof, evidence, quotations, paraphrasing, or plot references. A concrete detail is one complete sentence. Concrete details come from four places: “What I have read”; “What I have seen”; "What I or someone has done"; "What I or someone has said." Just because someone says something does not make it a fact. What someone says may be used as evidence/concrete detail, but make sure that the evidence you select is relevant, specific, and appropriate to the task. Dr. Louis recommends that evidence be pulled from credible, reliable sources. Wikipedia is not acceptable, because anyone with an opinion can write in Wikipedia. Just because a person has an opinion does not make that person an expert. Be careful. Look in databases, such as Gale Research, Google Scholar, Newsela. Libraries have wonderful sources.
