Organize your information like a newspaper so that your audience can quickly follow the thread of your experiment by reading from top to bottom, then left to right.
Use a font size of at least 16 points for the text on your display board, so that it is easy to read from a few feet away. It's OK to use slightly smaller fonts for captions on picture and tables.
A picture speaks a thousand words! Use photos or draw diagrams to present non-numerical data, to propose models that explain your results, or just to show your experimental setup.
Check the rules for your science fair. Here is a list of items that some science fairs allow (or even require) and some science fairs don't require (or even prohibit):
Your name on the display board
Pictures of yourself
Captions that include the source for every picture or image
Acknowledgements of people who helped you
