Hypothesis:
Makle a prediction about the densities of the unknown solid and the 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
