Virtual Sink or SwimName Montana RogersINTRODUCTION:You may remember being fooled as a child by the riddle, “which weighs more, a pound of feathers, or a pound of bricks?” Hopefully, you know by now that the answer lies in examining the differences in mass/volume ratios, or density. This lab is designed to provide other situations where the results may beunexpected.The density of a material depends partly on how closely the molecules of that material are packed. As molecules are more tightly arranged, a material becomes more dense. For objects within a fluid, substances that are more dense will sink to the bottom, while things that are less dense float to the top. For example, a rock sinks in water, but a piece of wood will float. Density is equal to mass/volume.PROCEDURE:PART A: Open the Virtual Physics Lab and select the Density module. Use the table below to calculate thedensity of the three given solids. You can calculate mass by taring the scale, and then dragging a mass
