I think the last year, that I did science fair (school hasn't held it in a while! 
)
I took a teaspoon of bakers yeast, and had 6 graduated cylinders, in each one, a teaspoon of yeast, and 2 teaspoons of water. I kept all 6 of them between 90-100 degrees fahrenheit.
In 3 of the vials I put a teaspoon of Splenda in (I guess I should explain that I was trying to see if yeast cells, could actually use the splenda compound[strike] in their energy cycle), in the other 3 I put a teaspoon of sugar (can't remember what type though) in.
I waited 30 minutes, then measured the levels that the bubbles where at on the cylinder.
Well, if I recall correctly, it seems that the splenda actually worked better, than the sugar.
I got an award, for the experiment.
I hope this gives you some Ideas.[/strike]

Just keep it nice and simple and you will get top ranked! My 7th grade year i did a VERY easy project dealing with plants and their soils. I came in 3rd place out of all the 7th graders

I won 2nd prize in HS science fair for making a bionic ear. Just take a parabola and a microphone and make recordings at differnt distances and sketch and explain the physics. if you are lucky like me, they will put you in the earth sciences and you will clean house.
although I am still angry about the person who won first prize, I remember "what can plants live without" gee, they can live without tons of things. cats, dogs, TV's, ect.... stupid judges

lol. i have a few questions. when you took it out with the sugar and splenda what is it suppose to look like? what are graduated cylinders? and what grade did you do this in?[/strike]
