The better your poster design, the more likely your audience will understand your project. Clear design starts with clear thinking. Now write down your answer. This is the theme of your poster, the focal point. Everything you include on your poster should support that theme.
Posters tell stories.
Your poster tells viewers what you did, why you did it and what you found out from doing it. For example, the poster that won third place last year detailed the author's cholesterol research in three columns. The first explained what enzyme was being studied and why. The second explained the method used and showed graphics of the student's work. The third was divided into sections on results and conclusions.
