Most science fairs have similar point systems for judging science fair projects.
I would instruct judges to consider every project average before even seeing them. Using a scoring system of 1 to 5, with 1 being the lowest point, then 3 would be average. As each judge evaluates a project, he or she decides if the project is average, if so, a score of 3 would be given. Points would be added if the evaluation is better or worse than average.
Following are ideas to be discussed with students about judging. Also, at the bottom are pointers for behavior at the fair.
1. Project Objectives
Defining the variables and using controls
2. Project Skills
3. Data Collection
Using a journal to collect data and research
4. Data Interpretation
Using research to interpret data collected
5. Project Presentation (Written Materials/Interview/Display)
DO’S AND DON’TS AT THE FAIR
Do become acquainted with your neighboring presenters. Be friendly and courteous. Do ask neighboring presenters about their projects, and tell them about yours if they express interest. These conversations pass time and help relieve nervous tension that can build when you are waiting to be evaluated. You may also discover techniques for research that you can use for next year’s project.
