... The purpose of this lab was to find the density of different objects byfinding their mass and volumes. I believe that, if the mass increases,then the density will increase. To investigate this hypothesis, my groupused a triple beam balance, a graduated cylinder, and a . We hadfive samples. These included aluminum, lead, copper, tin, and zinc. Webegan by testing the mass of the samples using a triple beam balance.Next, to get the volumes, we had to get the height and the radius ofeach sample. The final densities are found by dividing the masses andthe volumes. In this experiment, our independent variable was the typeof each sample and our dependent variable was the calculated densities. The first sample, aluminum, had a mass of 28.29 g, a volume of 10.5 cm,,and a density of 2.75 Dcal. The second sample, which was lead, had amass of 28.79 g, a volume of 2.68 cm,, and a density of 11.1 Dcal. Forour third sample, we used copper. The mass of the copper was 28.93 g.The volume was 3.54 cm, and the density was 8.17 Dcal. In the fourthsample, tin, the mass was 28.99 g, the volume was 4.15 cm,, and thedensity was 6.99 Dcal. For our final sample, we calculated 29.01 g forthe mass, 4.43 cm, for the volume, and 6.55 Dcal for the density.
