Is it a valid science fair project?

[deleted-64133]

I am a 10th grade student and i have planned to go for a science fair. I love Physics. The science buddies project about Refractive index of a liquid and its relation to sugar content was very interesting. I have now thought about a project idea which is based upon that very project...
"Is the Refractive Index of a liquid directly proportionate to its conductivity?"
In other words,
"Is the Refractive Index of a liquid inversely proportionate to its resistance?"

Do you think that it is a valid science fair project idea ????

Please anyone help me out with this !!!!!

IMO: Your question needs some refinement.

For realtively non-conductive things like sugar, the conductivity of the solution is not going to change with concentration of the solution.

For things that disolve and form ions, the conductivity of the solution will change with ion concentration. Hint: You might want to research the difference between molar and normal soultions.

The area where your question and resulting hypothesis need some refinement is in distinguishing between conductive and non-conductive solutions.
