Science Fair Help....?
I'm working on my Science Fair project and having some problems. The question I am trying to answer through my experiment is: how does temperature affect the density of a substance? To answer this question, I am using liquids and measuring their densities at certain temperatures. I'm having trouble measuring the density of the liquids. I know the formula for density is mass divided by volume. AND I think I know how to measure the volume of a liquid (but if you could include that in your answer that would be awesome. just so I can make sure.). My real question/problem is how do you find the mass of a liquid. I'm using coke, water, milk, and orange juice AND I just don't know how to calulate their masses so I can find their densities. Any help is appreciated...THANKS =)

The best way of doing this would be to use a graduated cylinder or some other measuring device. If you weigh the cylinder, then add your liquid and weigh that, take the difference of the two and you'll have the mass of the liquid.
As for the volume, if you have a graduated cylinder, you can measure out the amount and convert that to a volume: 1 cubic centimeter equals 1 milliliter.
