Try to design a display, which is simple, thorough, and easy to set up. Your materials and equipment should be placed in front of, or be attached to, an attractive background of a contrasting color (dark colors/light colors).
Your display should be self-explanatory. The average viewer should be able to quickly grasp what it is all about without needing you to be present to answer questions or provide explanations.
Examples of your observations and results should be part of the display. You may include drawings, photos, graphs, etc.
Be prepared to talk about your project and to answer questions from the judges!
This is where your notecards come in handy.
