I tested the acidic levels of bottled water for my science project. Just order a testing kit online, and record the data. The instructions are usually included.
My friend Peach will answer this any minute now...

if you can get your hands on a voltage meter (your dad might have one there pretty much ion every guys tool kit) you can take a 9 volt battery (one of the square ones) wrap some wire around the terminals ,best to use small guage electric wire like from an old broken radio or soemthing, then get a sheet of paper and draw a line about 4 to 6 inches long on it with a pencil , draw it on VERY heavy like as much as you can without cutting through the paper and dont make it way *** wide either no more then a quarter inch wide ,tape the receptors of the vu meter to the pencil line then touch the battery wires to the other end of the pencil line, the voltage meter will show that the electricity will carry through the pencil lead (actually carbon which is conductive) if you can find a flashlight you dont mind destroying you can get the bulb assembly (bulb and wires) out of it and tape the wires to the pencil line instead of the voltage meter so that when you hook up the battery the bulb will turn on. good luck!!

I did a project in 6th grade about the different boiling points of different liquids and how that helps in cooking and real life. Liquids can be water, salt water (or any other mixtures like sugar water...etc.), vinegar...maybe even dish washing liquid! (Though I have never tried it).
My friend did and acidity report on the acidic levels of bottled water. There are kits you can get online to find out the levels of acidity, or you would need a very intricate indicator.

candy? make some "rock candy", thats probably more like 3rd grade though. Eighth grade: make a solar system that hangs from the ceiling. The planets should be spaced propotionally to reality and the colors, rings, and other planet-specific details should be included. You could show poor little pluto with a sad face. Anyway, I got 3rd place with that one.

You didn't say what grade your hoping for or what age. But from the sounds of it compared to the examples you gave I would suggest going for one of my classic favorites. Putting an egg or old chicken bones in vinigar to see the effect. They become rubbery and effectively cartilage

if u have awhile until its due I would suggest getting daisys and putting food coloring in their water and monitor the progression. Its easy and requires almost no effort

Hard-boiled eggs will float in really salty water, but not in tap water. It's because of densities.
But don't quote me.
