Density of Liquids

In our most recent lab, we tested the density of certain liquids and we had to create the procedure. Our teacher gave us observations such as "When poured correctly, the liquids won't mix and will layer" or " The liquids are poured at an angle" and we also had to fill out the data chart. Some of the liquids that we used were, corn syrup, ketchup, and alcohols. It was really cool to see the different layers of liquids form.(although the ketchup was kind of disgusting) I reallly didn't think that it would actually work because, I have never seen any liquids layer up on each other, and I never hear of it. But I was surprised and not surprised to see it work the older kids probaly already did this so I kind of knew that it was going to work. First, my group tested the density of each liquid. I thought that the ketchup was going to be the densist, but when we tested the density, we found out that the corn syrup was the densist. Then we tested the density's of the alcohols. Our group found that E was the densist after D. But then, E and A had the same density. So we ( our group) randomly chose E to get poured on to d first, then we poured on A, and it worked!! We wrote our procedure, and it was, first, measure 15 mL of substance G. Pour into cup. Then measure15 mL of substance D, and pour at an angle slowly. Next, reapeat steps for E, A, B, in that order.When we were all finished, I thought that our lab was really disgusting. It was all ketchuppy. (it smelled like ketchup and our lab was red) But at the end, it was a really cool lab!!!
