Be sure to use language which can be understood by all on-lookers.
Ensure that you understand all of the information being presented. A question may be asked relating to any aspect of the project.
The main goal is to present all information in a clear and understandable way.
DO NOT memorize a script. Instead of notes, consider using the display as a guide for the presentation. If notes must be used, use point form notes outlining important points to discuss.
Relax and have fun!
