Density Lab Part II

All of your data is aggregated on this spreadsheet.  Look at the tab labelled "Part I consolidated data" and on the individual tab for your material.  I have added data from previous years as many of the data sets provided were incomplete or contained significant errors.   

As with the part 1, you can copy the data into a new tab or spreadsheet to manipulate.  The master sheets are protected.  

For Part I

• Compare the values used to determine the volume of the cylinder.  
• How would you describe the precision of these measurements?  
• Which is better, height or radius?
• How does this effect the calculation for the volume?
• How do the measurements for the Sphere compare to those for the cylinder?
• What is the resolution for your vernier caliper?  The balance?  How is this reflected in your calculation?

For Part II  Look at the tab for the type of metal you used.  You can make a copy of this lab if you wish to manipulate the data, otherwise do the work in your notebook.

• Plot the Mass versus Volume for all of the data shown.  
• Which has a higher precision, mass or volume measurements?  Explain your answer.
• Is there a relationship between the accuracy of the results and the size of the object?  Explain.
