Step 14: Write the Abstract (this should be the last thing that you write!)
An abstract is a summary of your project. It should state your research question, purpose, and hypothesis. It should include a summary of your procedure, but you do not need to be as precise as you were in the procedure section; describe your steps more generally. Your results and conclusion should also be included. The abstract is meant to give a quick explanation of your project to someone before they start to read your paper and examine your display. Reference the science buddies web site for additional information. Final draft of the abstract must be included on your display board.
