The science fair is a tradition that goes way back. It focuses on elementary, middle, and high school students. The iconic competition allows young minds to apply different scientific processes in answering questions and solving problems that captivate them.

Apart from that, it is a vital academic barometer that teachers can utilize to gauge how far their students are in mastering various scientific concepts. You need a terrific topic or idea to crash any science fair competition. Other than a unique theme, here are other important attributes that science fair judges will be on the lookout for:

  • Research question – states the problem you look to tackle in question form. It should be clear, identifying a certain contribution to a given field of study.
  • Design and methodology: To get the full mark, you must develop a well-structured plan and an awesome data collection technique. It is also vital to define different controls and variables.
  • Execution: The stage demands proper data collection and analysis to support your conclusions and interpretation. You also need to show proper use of statistical and mathematical methods.
  • Creativity: The project of your choice should display your creativity and out-of-the-box thinking capacity.
  • Presentation: It is the most integral part of any project. The presentation part evaluates your ability to communicate your ideas effectively. It also tests how clear and logical your work is organized.
