During the lab, the whole purpose of the lab was to determine density of both regular and irregular shaped objects. Throughout the lab I found out that both of the small and large silver rod, do not have the same density, and also found out that the gold rod is not real gold. My hypothesis is that since, the large and small silver rod has about the same density I believe that they would have about the same amount of volume. They both might displace the same amount of water on the graduated cylinder. The Materials we used throughout the lab was:

Metal rods (Gold & Silver)
Wooden block
Water
Scale
Ruler
Procedure thought out the lab:
1. First step we did was get the materials and went to out stations with our partners. 2. Second me and my partner measured the mass of the metal rods and the wooden block and recorded them on the worksheet. 3. After we filled up the graduated cylinder with water and dropped one of the metal rods and the water, the water amount that increased in the cylinder was the volume of the rode that was placed in. 4. We continued to measure and record the volume of each of the metal rods the same way as the first. 5. We measured the length, width, and height of the wooden block and recorded it. Then multiplied them altogether to get the volume of the block. 6. After gaining the measurements of the mass and volume of the...
