Adjusting the jaws and turning the screw clap appropriately until the jaws were securely fastened around either the diameter, or the height of the object was the apparatus used to properly obtain the measurements needed. This procedure can be quite meticulous and due to its delicate and sensitive nature, may easily introduce error into the measurements, ultimately effecting the integrity of the results from the experiment. Nonetheless, the utilization of this technique would ultimately assist in determining the volume by providing accurate measurements to insert into the appropriate formula.

The calculated volume would then be used, in conjunction with the mass, to determine the density Of the metal in question. In order to measure the mass of the object being experimented on, a balance beam was used. Placing the object on the scale and measuring the exact mass of the object was quite challenging in the sense that factors such as swaying or pushing a weight too far down the scale had a considerable effect on the accuracy of the measurements, introducing further possibilities for error.

This could prove to e a problem when taking multiple measurements of the mass of each object. However, becoming further acclimated and comfortable using the equipment over multiple experiments also helped decrease the chance of repeating the same mistake while taking a measurement. The measurements received from these tools enabled the proper calculation of both volume and ultimately density. The results yielded a density of 2. 79 g/com, which is a fairly accurate calculation, given the fact that the accepted value for the density of aluminum is 2. 1 g/com. Using the percent error formula yielded an answer that indicated the result achieved in he experiment had a percent error of less than 3%, further affirming the proper execution and completion of the assigned experiment. Conclusion The ultimate objective of the experiment was to determine accurate measurements of the diameter, height, mass and volume of these metal cylinders. By gaining this information, it then becomes possible to calculate the density of the aluminum metals.

Although the conceptual aspect of this experiment is easy to grasp, the method of execution offers a variety of ways to inadvertently introduce error into the experiment. From malfunctions Of he fernier caliper, such as not having the jaws securely around the object, to slight inconsistencies, such as reading on the wrong side of the sliding weighing indicator on the balance beam when measuring the mass, the opportunities for error to influence the results becomes a prominent concern.

As the results indicate, although not exact, the measurements discovered in the experiment conducted were very close to the accepted value. These findings coupled with the relative consistency with these findings in comparison with the accepted values all confirmed the notion that the experiment was conducted properly and executed fully.
