For which object does the method of volume by displacement give an inaccurate result? Why? A4. Calculate the density of each object (use the volume by displacement determination of the volume for each object except the wooden sphere; for the wooden sphere use the volume calculated from the diameter). Show all work with units and record your answers in the table below to the correct number of significant figures and with proper units. Show work: Table 2: Density Results Object Calculated Density lead sphere iron sphere wood sphere unknown sphere gold nugget A5. Predict the identity of the substance of your unknown sphere by comparing its density to those in reference Table 3.

Density Name Date PART A: DENSITY OF REGULAR AND IRREGULAR SOLIDS Note: Remember to record all measurements with their associated units and to the correct place value. Procedure: Measurements and Observations: 1. Open the online simulation software from Sapling Learning. Object 2. Measure and record the mass in grams of each solid object on the workbench. Note that the analytical balance used in this activity is precise to the thousandths place. Don't forget to also include units in all Mass lead sphere 47,460g 263.60g 79.1709 31,3809 31.1009 iron sphere wood sphere measurements. unknown sphere 3. Measure the diameter of each spherical object using the ruler provided. Slide each object over the ruler until one edge is on the zero marking and the middle of the sphere overlays the ruler markings (the diameter is the maximum width). Read and record the diameter of each sphere to the correct place value and with the proper units. (In the data analysis section, you will use the formula for the volume of a sphere (V = TdP/6) to determine the volume of each sphere.) gold nugget Object Diameter 2.00CM 4.00CM 6.00CM 2.00 CM lead sphere iron sphere wood sphere unknown sphere 4. Measure the volume of water displaced by each object by placing each object separately into the graduated cylinder provided. Record the initial water level and final water level for each to the correct place value and with units.
