Your Oral Presentation

In presenting your project to the judges at a science exposition, the following approaches have proven successful for many students.  Your presentation should not exceed 10 minutes.

  1. Introduction
    • State your name(s), age, school.
  2. Acknowledgements
    • Give credit to those whom you have contacted and to those who have helped you. Discuss any work done in the past pertaining to your project.
  3. Purpose and Hypothesis
    • State exactly what the investigation is attempting to discover.
    • Hypothesis (If, then statement) - Make a prediction about the outcome.
  4. Background Information
    • Background explanation for your project (to familiarize the judges)
    • This is a summary - DO NOT read your entire research paper to the judges.
  5. Procedure
    • Be complete – do not leave out necessary details.
    • Proceed in a logical manner, telling what you did step-by-step.
    • Use visual aids: charts, pictures, graphs, etc. Point to your display, but stand aside when you do this.
    • Explain how your apparatus was used. If you constructed it yourself, tell the judges you did, if not, give credit to those who helped you.
  6. Results (Data and Discussion)
    • Explain both your controls and your experimental variables.
    • Remember to use proper metric units of measure with your data.
    • Point to graphs, charts, etc., when you refer you them.
  7. Analysis - Analyze and discuss statistical aspects of experimental errors such as averages, ranges and/or other statistical analogies. 
  8. Conclusion
    • State in a concise/logical order the conclusion you can validly draw from the experiment you have done and the data and/or observations obtained.
    • Refer back to your hypothesis and tell if the results support or do not support it. (Remember your hypothesis is simply an educated prediction as to what your results may be and the actual results may differ considerably.)
    • Admit any deficiencies or limitations in this regard – judges respect this. This should be part of the experimental error discussion.
  9. Future Plans - Be sure to tell how you plan to continue your project, if applicable.
  10. Any Questions
    • When you have finished, ask the judges if they have are any questions
    • When they ask you questions, think before you answer them. Answer slowly! If you do not know the answer say, “I really haven’t been concerned with this in my project, but it might be interesting to look into it."
    • Thank them for any suggestions they may have for bettering your research.
  11. Other Suggestions
    • Speak slowly!
    • Be forward but polite, dynamic, and interested in your experiment topic.
    • Remember that you are a sales person and therefore your job is to sell your product to the judges. The judges are interested in your work – which is why they are judging you.
    • Your presentation should not exceed 12 minutes.
