Lab Report Standards of Excellence
Introduction/ Objective/ Problem Statement:
 A problem statement is written which identifies the independent and dependent
variables in the experiment. (3 points)
 What was the objective of these labs?
 Independent variable  The form that copper takes (i.e copper
hydroxide, copper oxide, etc)
 Dependent variable  Amount of copper
 Background scientific concepts are included and explained. (1 point)
 What is the Law of Conservation of Matter?
 A hypothesis is included indicating the predicted results. (1 point)
 Predict what you think will happen to the amount of copper if you
change it’s form through several chemical reactions.
_____ out of 5
Experimental Design:
 Materials are listed. (1 point)
 Numbered steps of procedure are clearly stated. “Gather materials” & “Clean
up” are not necessary. (1 point)
 Could be used to reproduce the experiment; specific measurements and
techniques are evident. (1 point)

Conclusion:
 Begins by restating the objective/problem statement from introduction.
(1 point)
 Is a summary of the general trend you observed from your data. (1 point)
 Was the mass of the copper the same in the beginning as it was for
your final measurement?
 Includes a few specific examples from your data to support this summary.
 Thoughtful comments about your confidence in your results are included.
Specific explanations of errors made which may have impacted your results are
discussed. (1 point)
 Relevant improvements to reduce these errors are suggested. (1 point)
 A suggestion for further investigation is made to expand upon the original
problem/objective/hypothesis. (1 point)
 What else could you do to investigate the conservation of matter?
_____ out of 6
Writing Quality:
 Writing quality meets the standards of the KHS writing rubric. (1 point)
 Writing is formal; no “I” statements, no commentary that includes feelings
about the experience. (1 point)
