Each example uses a different evidence structure. Choose the one that matches the kind of question you actually investigated, not just the topic.
Who uses it: A student running a controlled comparison
Why this works: A compact table makes the independent variable and measured outcome easy to compare.
Who uses it: An elementary science project
Why this works: The board uses plain-language labels while preserving the controlled variables and numerical result.
Who uses it: An engineering design project
Why this works: The board compares iterations instead of forcing an engineering process into a hypothesis format.
Who uses it: A student measuring temperature change
Why this works: Time-series data belongs in a chart, with the measurement method next to it.
Who uses it: A field observation project
Why this works: A small site map explains where counts came from without implying experimental causation.
Who uses it: A design-and-test project
Why this works: Repeated trials and an average keep one lucky throw from becoming the whole conclusion.
Best when one variable changes while other conditions stay as consistent as possible.
Best when you record patterns without assigning treatments; avoid claiming the observed factor caused the result.
Best when success is defined by criteria and constraints, followed by testing and redesign.
A result such as “13” is incomplete without centimeters, seconds, grams, or another unit.
Show repeated trials when appropriate and be honest about variability and limitations.
Use one readable chart rather than several tiny charts with illegible labels.
A common reading path is question and background, then method, then results and conclusion. Keep related evidence and claims near one another.
Show enough values or a summary table to support the result. Put extensive raw data in the project notebook unless your fair requires it on display.
Yes, when allowed. Add short captions explaining what each image demonstrates, and protect participant privacy and source attribution.
