Density Lab x axis being mass on the graph and y axis being volume Measured density of aluminum, brass, steel, copper, nylon, glass 1.What does a steeper line on your graph mean? a.higher density b.lower density c.no change in density d.unrelated to density 2.What is the dependent variable in this experiment? a.mass b.volume c.density d.time 3.Two equal sized metal rods are being compared. The brass rod has a mass of 3 kg and the titanium rod has a mass of 2 kg. Which rod is more dense? a.brass b.titanium c.both have the same density . 4.If the experiment were changed so that you were given equal volume pieces of each material (volume becomes independent variable) and had to measure the mass (mass becomes dependent variable), how would the graphs change? a. The new graph would have a negative slope b.The new graph would have zero slope c.Both graphs are similar in shape and have positive slope d.It doesn't change the graphs at all 5.How would the graphs change if the material being measured was not uniform? (Non-uniform materials have varying density from piece to piece.) a.The graph would curve upward in a smooth curve b.The graph would not change c.The points on the graph would be scattered around d.The graph would curve downward in a smooth curve
