  1. DATA AND OBSERVATIONS DATA TABLE 1PART A: DENSITY OF WATERMass of empty graduated cylinder (g)Mass of graduated cylinder and water (g)Mass of water (g)Volume of water (mL)Density of water

  2. DATA TABLE 2 PART B: DENSITY OF A RUBBER STOPPER Mass of a rubber stopper (g) Initial volume of water in graduated cylinder (mL) Final volume of water in graduated cylinder (after placing the rubber stopper) in mL. Volume of the rubber stopper (mL) Density of the rubber stoppe (g/mL)

  3. DATA TABLE 3 PART C: DENSITY OF MARBLE Mass of marble (g) Initial volume of water in graduated cylinder (mL) Final volume of water in graduated cylinder (after placing the marble) in mL Volume of marble (mL) Density of marble (g/mL)

  4. ANALYZE AND CONCLUDE Using Numbers Use the mass and volume data to calculate the densities of water, the nail, and marble. Record these values in the data tables. Observing and Inferring Did the volume of water change when an object was placed into a graduated cylinder that was half-filled with water? Predicting Would you expect the densities of various fruit juices to all be the same? Explain.

  5.   Drawing conclusions When you use the terms heavier and lighter to compare objects with the same volume, what property of the objects are you actually comparing? Connection: Real World Chemistry How can the concept of density be used to differentiate between a genuine gold and an imitation gold?
