What judges look for in your science fair project.

Examples of science projects entries in the past I have given low scores to are yogurt making, cotton candy, fingerprinting and candles. These projects gave no descriptive formula for the processes occurring and were not related to the standard laws of magnetism, motion or electricity.

Some of the science fair experiments I have judged covered from middle school science fair projects through to high school. The science fair project ideas using water rockets have always been one topic that captures my attention and interest.

Here is the science fair judging worksheet I use when I judge school science fair projects.

Title of Project _____________________________

Evaluation of the Experiment

How is this project different or new from all other projects?

Project has:
No problem statement
Incomplete problem statement
Complete problem statement
Statement generates new ideas, is well written and clearly displays exceptional criteria.


How testable is the prediction?

No hypothesis
Hypothesis is incomplete
Hypothesis is present, but not testable
Hypothesis is exceptional, giving clear insight and highly accurate predictions

Project Design

How does the plan conform to give the hypothesis meaning and truth?

Plan does not validate or confirm the hypothesis
Plan is partly created, to confirm the hypothesis
Plan is acceptable to confirm the hypothesis
Plan is extraordinary, it validates, confirms and makes new predictions for future hypothesis experiments.

Project Procedure

How does the experimental process connect with the hypothesis data and its results

There are no experimental procedures used
The procedures are complete, but not listed step by step
Experimental procedures are listed completely step by step
Experimental procedures quantitatively are listed clearly and accurately

Controls and Variables

Are the variables listed and controlled?

No variables are identified or controlled
Variables are present, but not controlled
Some variables are identified and others are controlled
Variables are exceptionally clearly identified and controlled

You are welcome to print out my worksheet. I've made a printable page version

Science fair project examples that I have given high marks to in the past have included: Parts of an electric motor, the solar system, water filtration, models of cities of the future and water rocketry.

When judging water rockets, I include the following in my worksheet:

What is the effect of gravity on the rocket?
How/to what extent does air resistance affect the rockets performance?
What makes the water rocket fly?
Can you back up the theory that sustained air pressure is what creates the thrust?

Good data and research presented with your water rocket adds credibility and points when displayed at a science fair.
