Measuring Mass, Calculating Density • Activity 9
Part C: Using Density to Identify Materials
9. Now that you have calculated the density of several objects, you will use
this to identify the material each of the objects is made from. In your
science notebook, make a table similar to Table 2, “Identifying Objects’
Material Using Density.”
Table 2: Identifying Objects’ Material Using Density
Name of object Density calculated Closest density from Table 3 Object’s material
10. In your new table, fill in the name and density calculated for each
object from Table 1, “Mass, Volume, and Density of Six Objects.”
11. Compare the densities you calculated in Table 2 with the densities shown
in Table 3, “Densities of Selected Solids,” on the next page. Find the
density closest to the density of each object, and enter that in Table 2.
12. Identify the material that might make up each of the six objects.
Hint: Look for the material that has a density closest to the density that
you determined for each object. Write the density and the material of
this object in Table 2.
This bowling ball and balloon
have very similar volumes,
but because the bowling ball
has more mass per volume,
it is more dense.
