group’s findings compared to those of the second group testing the same materials did not support our claim. In our experiment we measured two set of densities, one for the calipers and the other for the graduated cylinder. Using the measurements obtained from the calipers the first group obtained a density for the cube of 1.99 g/cm³, a black cylinder of 2.11 g/cm³ and a blue cylinder of 1.93 g/cm³. On the other hand, using a 10 mL graduated cylinder a density for the cube of 1.40 g/mL, a black cylinder density of 1.42 g/mL, and blue cylinder density of 1.87 g/mL was collected. After finding the objects density the first group compared their measurements to the second group and their findings. For example, their density for the cube using the calipers was 1.228 g/cm³, for the black cylinder was 1.392 g/cm³, and for the blue cylinder it was 1.094 g/cm³. By using the graduated cylinder their results happened to be a cube with a density of 1.20 g/mL, a black cylinder with a density of 1.4 g/mL, and a blue cylinder with a density of 1.1 g/mL. Examination of similarities between the second group and the first group reveals that the objects are not the same material but within the first group, it signifies that they are. One difficulty the first group had in resolving the data for density is determining the amount of sig figs. They rounded every measurement; volume, and density with the exception of the objects mass to three sig figs, rather than just rounding its density when all was gathered.
