How do I go about writing an outline for a research paper about Mammoth Cave in KY? There is so much I can write about. I'm lost!

First of all, you need to know whether the paper must be persuasive or informative. If it must be persuasive, you would need to find some controversy surrounding the cave and take a side. I'm going to assume your paper needs to be informative, not persuasive. In that case, think of broad categories that would interest you and your readers. Start by asking questions about it. Perusing the website may help you formulate some questions. After you make a list of all the questions you can think of, then try grouping them into similar categories. Aim for three main categories, which will be the three main points in the body of your paper. Then you need an introduction at the beginning and a conclusion at the end. These should be included in your outline.

To fill in the subpoints under the three main points, go back to the questions you asked. Some of those questions may form the subpoints of your outline. You must have at least two subpoints under each of the three main categories. 

If you find interesting facts during your initial browsing of the website that don't fit under any of your main categories, you may be able to use those in your introductory paragraph. Your introduction should start with an attention-getting comment. Then it should contain some background information about your topic, in this case some general information about the location of the cave and why it is so famous. Then introduce each of your three topics.

In your conclusion paragraph, summarize your three topics, then make a comment about what you believe is the most significant thing about Mammoth Cave and why. Then end your paper on a strong note in a way that refers back to your attention-getting opener. Your outline for your introduction and conclusion paragraphs should include the points I've mentioned here.
