Title: Measuring the Density of Various Objects
Problem Statement:
How do the densities of the objects compare?
Method and Materials:
Measure the mass of each object with the balance. Measure the volume of each object by
filling a graduated cylinder with water to a set level. Drop the object into the cylinder
with the water and measure how much the water level rises. That is the volume of the
object. Density = mass divided by volume.
Hypothesis: (List the objects in the order that you think will
be from most dense to least dense.)

Part 2:
Measure the density of a rubber stopper, then and measure the density of
two rubber stoppers.
Hypothesis:
How do you think the density of one rubber stopper will compare to
the density of two rubber stoppers?

Part 3:
Measure the density of water:
(You have to figure out how.)
Mass (g)
Water
Discussion Questions: (Type and attach)
1. Explain why the results for the rubber stoppers came out the way they did.
Make sure that you use the formula for density in your answer.
2. Explain the method you used to measure the density of water?
3. If an object has a density of 1.9 g/ml would it float or sink in water?
Explain.
Conclusion: List the objects from most to least dense
