Density Lab
Measurement and Density
Your Name: ____________________________________________________________
__ Purpose of this Lab
What is the goal of this lab? What question are you trying to answer, or what problem are you trying to explain?
Hypothesis
After reading the lab instructions - but before starting the lab - record your best “educated guess” about each experiment: Experiment 1: Which method of finding the density give you the least percent error and why? Experiment 2: After completing the first experiment, answer this question. Which block do you think has the highest density and why?
Experimental Design
List the materials used in this lab, and write a brief explanation of the procedures you followed. (You do not need to retype the procedure; simply summarize your procedures you used.) Procedures: Materials:

Show all work in all questions requiring calculations. Use the following density table when needed. Density Table Substance Aluminum Oak Pine Polypropylene PVC Steel Water Lead Bismuth Density (g/cm3) 2.70 0.75 0.42 0.92 1.40 7.9 1.0 11.4 9.78
1. Suppose you were asked to find the density of a metal object that appears to be a cube. You notice that the metal looks old and has a few chips in it. Without any other information, would it be correct to measure 1 side of the object and cube (^3) the value to determine the volume? Explain.
2. Suppose you determined the density of a cube to be 1.40 g/cm3. Would the density of the cube be different if you had a cube made of the same material with twice as much mass? Explain.
3. A cube with a mass of 0.0084 kilograms has a volume of 20.0 cm3. Using the density table above, identify the object. Don’t forget to convert if needed.
4. A cube of lead is 7.00 centimeters per side. What is the mass of the cube? (See table for density of
