The purpose of this experiment is to compare the different densities of different liquids. Density is a comparison between an object's mass and volume. Density = Mass divided by Volume. If the weight (or mass) of something increases but the volume stays the same, the density has to go up. If the mass decreases but the volume stays the same, the density has to go down. This experiment will show how the weight of certain liquids react to each other.

The seven liquids I have chosen for the experiment have different weights and textures. My hypothesis is that the liquids that have more density, even though I am using the same amount of liquid, will be on the bottom of the column. The liquids that are less dense will then layer on top of the more dense liquid. They will create a layer of seven different liquids one on top of the other.

Most of the research I did for this experiment was online. I found a lot of different information about the densities of different liquids. One web site that was most helpful was stevespanglerscience.com. I learned how different liquids have different densities. The same amount of oil has a different density than the same amount of water, for example. I also watched a video on youtube.com showing how the experiment works. Some liquids that have different densities are baby oil, vegetable oil, water, milk, dawn dish soap and maple syrup. Each one can be measured out in the same amount, but will have different densities.
