Option One: Density Measurements Virtual Lab
Instructions: For this investigative phenomenon, you will need to determine the densities of an
unknown solid and liquid using different methods of measurement to determine if the solid will
float on water. Record your observations and test measurements in the lab report below. You will
submit your completed report.
Title: density measurement virtual lab
Objective(s): find density of unknown solid and liquid
Hypothesis:
Make a prediction about the densities of the unknown solid and liquid. How will mass affect the
volume of the solid, and how will volume affect the mass of the liquid?
Procedure:
Access the virtual lab and complete Part I and Part II trials of the experiment. Because this lab is
virtual, summarize the steps in which data were collected for the samples. In addition, list and
explain your controlled variables, independent variable, and dependent variable for this lab.
Materials:
Laboratory Techniques Virtual Lab
Variables:
Remember, controlled variables are factors that remain the same throughout the
experiment. An independent (test) variable changes so that the experimenter can see the
effect on other variables. The dependent (outcome) variable will change in response to
the test variable.
Controlled variables: volume of liquids
Independent variable: empty graduate cylinder
Dependent variable: Mass of graduated cylinder and liquid, volume of water and solid
