Gather your background information. This is probably the most important step in the process. You need to know all about your subject if you are going to present an audience or reader with information. If you want to discuss alcohol, you need to convince your reader that you are an authority on the subject. That is why preparation is key. You might want to also consider indexing your sources on index cards that way you can refer back to them later if there are any questions.
Outline important sections that you plan to include. To help you with this, answer the following: What about alcohol do I want to say? Some possible subject areas could be background, history, chemical composition, prohibition, effects, classification, uses, addiction, harmful side effects, cultural attitudes or media portrayal. These are just some possible suggestions that you could use to direct your presentation.
Direct your message. What are you trying to persuade the audience to believe? Perhaps, you just want to take an informative approach. Depending on your directive, a persuasive approach requires that you support your stance with information about alcohol that strengthens your argument. Where as informative enables you to be more generalized with the information you plan to include in your presentation.
Draft your written presentation using your outline as your guide. The introduction should clearly state what it is you are talking about, why you are talking about it and what you want your audience to get from the rest of the presentation. Being direct about your presentation on alcohol will enable the audience to follow you better and help keep their attention. Bridge your introduction into your body paragraphs; transitions are useful for this.
Develop your body paragraphs. Using your outline, start getting into the gist of your presentation. The body paragraphs should be concise and flow from one to the other. The whole of your paragraph should talk about your one idea and your opinion and/or research on it. Strengthen your presentation by sprinkling quotes from relevant sources into your presentation. Unless you are an authority in your own right on the subject of alcohol, such as drug counselor or a medical physician, you will need to frame your ideas with the position of others.
Close your presentation by reminding your reader or audience the purpose of your presentation and what you were able to prove to them or inform them of. Since this is your last chance to impress your reader, remain short, concise and end with a sort of impact. Impact can be from a quote or a startling statistic about alcohol.
