Activity A (continued from previous page)4. Analyze: Look carefully for patterns in your data.A. Does mass alone determine whether an object will float or sink?Explain:B. Does volume alone determine whether an object will float or sink?Explain:C. Compare the mass and volume of each object. What is true of the mass and volumeof all the floating objects?D. What is true of the mass and volume of all the sinking objects?5. Calculate: The density of an object is its mass per unit of volume. Dense objects feel veryheavy for their size, while objects with low density feel very light for their size.To calculate density, divide the mass by volume: D = m/N. If mass is measured in gramsand volume in cubic centimeters, the unit of density is grams per cubic centimeter (g/cm)Calculate the density of each object, and record the answers in the last column of your datatable. Label this column "Density (g/cm³)."6. Analyze: Compare the density of each object to the density of the liquid, 1.0 g/mL. This isthe density of water.A. What do you notice about the density of the floating objects?B. What do you notice about the density of the sinking objects?7. Draw conclusions: If you know the mass and volume of an object, how can you predictwhether it will float or sink in water?

Solution: 4(A). The mass alone does not give the idea of whether it will sink or float. The density…
