Density Rainbow Lab Conclusion

During this experiment, we ranked four solid blocks and seven different colored solutions from least dense to most dense while creating a density rainbow. However, during the creation of the density rainbow, two of the blocks stuck together and broke the seal between two colors, causing the colors to blend together. Introduction: Density is the amount of mass per unit volume, or how solid an object is. Density is found by dividing mass by volume. Density is very important in life as it determines characteristics of an object, such as if it is able to float or not. Hypothesis: If I correctly calculate the densities, then I will see a proper density rainbow because substances will separate by their densities. Materials: Separatory Funnel Weighboat…show more content…
Each solution that was added to the rainbow pushed the previous solutions or solids up because the solution had a higher density than the previous solutions or solids. For example, when the orange solution was added, it pushed both the red solution and the wood block up because the density of the orange solution was greater than both the red solution and the wood block. Using our calculations and the rainbow, how could we predict what we saw in this activity? We could predict what we saw in this activity by ranking the densities of the solutions and the solids from least dense. Solutions and solids with a lower density will be at the top of the rainbow, while solutions and solids with a higher density will be near near the bottom. If you know the density of all the solutions and solids, you would be able to predict how the order of the rainbow would look. Use a Known Densities of Substances chart to predict what the four unknown solids actually are? The metal block or Solid 1 is Aluminum. This has a density of 2.996 g/cm3. The clear block or Solid 2 is Nylon. This has a density of 1.216
