Conclusion/ Evaluation
Using the densities I calculated in the lab I identified 8 of the 9 objects. They are as follows: Object 1: ????? - Object 6: Cork Object 2: Brass - Object 7: Wood Object 3: Acrylic - Object 8: Rubber Object 4: Aluminum - Object 9: Iron Object 5: Nickle I was able to correctly identify some of the objects, but in most cases my densities were slightly different for that object. If I could do this again I would re-calibrate the scales every use and try to cut out human error by having more than two people collecting data.
