Choose something you know about.
Choose something that you are interested in AND that you think might be made interesting to your audience. An esoteric topic like, for example, the various ways of making paper might be rather dull to most people (unless you can find a "hook" to make it interesting).

Sometimes a good way to find a topic is to start with a quotation such as, "Early to bed and early to rise makes a man healthy, wealthy, and wise." Build on that (or some such adage or quotation) to make three points about it, pro or con (or both).
Keep in mind that when writing a speech, no more than three points should be made. The audience will, most likely, not remember more than three. You need an introduction to tell them what you are going to tell them, then make your points, and a summary to restate the three points (in brief). So, three points, stated three times. :)
