I was right.
Thought the 4th cube was copper, I was right. Thought the 5th cube was acrylic, I was wrong, it really was nylon. I thought the 6th cube was pine, I was wrong, it was really oak. I thought the 7th cube was PVC, was right. Thought the 8th cube was oak, I was wrong, it was really pine. I thought the 9th cube was poplar I was right. Thought the 10th cube was nylon, I was wrong, it was acrylic.
Conclusion To calculate density you divide the objects mass by its volume. The units I used or volume were CM, for mass g, for density g/cam. When the cubes are placed in water the one that will sink first is the black cube because it has the most mass and is the most dense.
The ranking in cubes from lightest to heaviest is; dark wood, white plastic, light wood, medium wood, clear block, gray plastic, shiny solid gray, gold colored cube, dull penny, and the black. No, it is not necessarily true that the object with the most mass has the most density, because the volume could vary.But, in this situation the object with the most mass is the cost dense because all of the volume’s are the same. Discussion During my density lab I made a make a big mistake. This mistake was calculating the density wrong, because my volume measurement was incorrect my density measurement was also incorrect. The reason that my volume was wrong was because my partners and I used the wrong side of the ruler and just estimated the value in centimeters.
But, at the end of my project when i figured out my volume was wrong I rewrote my graph using the correct volume. My project is now fixed!
