January 31, 2007 Physics Lab 124-021 Alexander Hyatt Abstract The experiment carried out in the lab involved measuring the dimensions of and massing several different types of aluminum objects. The out of class assignment was to organize the data collected into a table and to make a graph that showed the relationship between mass and volume. This relationship between the two subjects is density. Also, a graph that showed the relationship between the Fahrenheit and Celsius scales was made in the same way. Finally, percent difference calculations were calculated to show the difference between measurements of the same value. All in all, this experiment helped to determine the relationship between mass and volume to be density, and to get us to correctly graph and perform calculations, specifically error calculations, in a lab report.

January 31, 2007 Physics Lab 124-021 Alexander Hyatt The table above (Table 1) is a listing of the measured dimensions for each aluminum object, with exception to the volume, which was calculated using the appropriate formula for the shape of the object. The only exception to the volume being calculated is the hexagonal bar’s volume, which was calculated by finding its displacement of water in a graduated cylinder. Also, the mass of each of the
