Pre-Lab Study Questions
1. What property of oil makes it float on water?
Water has more density than oil
There is more water mass than oil per unit volume
2. Why would heating the gas in a hot air balloon make the balloon rise?
Because there is hot air inside the baloon (from the heater/bun
and it makes is less dense than the air of the outside the
baloon
3. What is the difference between density and specific gravity?
Ratios of each other. Density is the measure of the
amount of mass per volume. Specific gravity is a measure
of density relative to the density of a reference substance

Purpose - Part 2: The second purpose is to determine the relationship between the ml, g,
and cm³ of the same amount of water.
Procedure - Part 2:
1. Using a ruler, measure the length and the width of the inside of your box to the nearest 0.1 cm. Record the
values in the table below.
2. Each person in your group chooses a value between 20 and 100. Record everyone's value in the last
column.
3. Carefully place the box and water on the balance. Measure the mass of the box and water and record the
value on your data page.
4.
Fill the graduated cylinder with the amount of water you wrote in the first row of the last column. Pour that
water into your box. Using a balance, measure the mass of your box to the nearest 0.1 g. Record the
value on your data page.
5. Subtract the mass of the box to determine the mass of the water.
6. Measure the height of the water inside the box.
7. Find the Volume of the box by multiplying length x width x height.

7. Analyze: Drag objects C and E into the water. Estimate the percentage of these objects that are submerged
below the waterline. List these estimates below:
Object C: |
Object E:
How do these estimates relate to the densities you calculated above?
8. Think and discuss: Why can't you use this Gizmo to measure the densities of objects B, D, and F? If
possible, discuss your answer with your classmates and teacher.
B,D,F do not float so we cannot find their mass based on water displaced
9. Challenge: What can you say about the densities of objects B, D, and F? Is there a way to compare the
relative densities of these three objects? Explain.
