Before conducting an investigation, a student measured and recorded the masses of a strip of zinc (Zn) metal and a beaker
of copper sulfate (CuSO4) solution. The student then placed
the strip of shiny, silver-colored zinc metal into the solution
and observed the changes. A visual anchor of the
investigation and her observations are below.
