The purpose of this experiment was to introduce the concept of measurements, error, and graphing that we will use in future in experiments. We used a meter stick, vernier caliper, triple-beam balance, and graduated cup with water to calculate our measurements. Our data concluded that the density of the aluminum to be 2.79 g/cm 3 calculated from the slope of mass versus volume graph. Comparing the actual density of aluminum which is 2.70 g/cm 3 to our calculated density, our percent error was 3.3%. Data and Equations: Data: Table 1.
