establishes the central question
of the experiment, provides a
testable hypothesis, and outlines
a method for achieving these
goals
The extent to which the report
demonstrates an accurate,
clear, and organized
presentation of the information
gathered during the lab
procedure

demonstrates a thorough analysis
of the results, identifies key results
or trends in the data, includes
graphs (if applicable), and utilizes
logic and reasoning to explain
results
The extent to which the report
addresses the hypotheses based
on data and offers ways in which
the experiment might be
improved

the hypothesis to be tested
during the lab are clearly
identified and stated. Procedures
are listed in clear steps. Each step
is a complete sentence.
Very Effective

presented accurately and
clearly, and organized in a
logical fashion. The
presentation of the results is
very concise and focused.
Very Effective

Graphs (if applicable) are labeled
properly and neatly displayed. All
important trends or patterns in
the data are identified and
discussed. A reasonable and
focused discussion is provided in a
logical order.
Very Effective
The hypotheses are evaluated
effectively, and data and results
are used to support the
conclusion. Recommendations
on how to improve the
experiment are included, and
demonstrate an excellent
understanding of the experiment
and procedure.

during the lab are clearly
identified and stated. Procedures
are listed in a logical order, but
steps are not in complete
sentences.
Good
All data and observations are
presented accurately and
clearly, and organized in a
logical fashion. The
presentation of the results is
not concise or lacks focus.
Good
All key results are identified.
Graphs (if applicable) may have
minor problems with labeling or
neatness. Most trends or patterns
in the data are correctly identified
and discussed. A reasonable and
focused discussion is provided in a
logical order.
Good
The hypotheses are evaluated
effectively, and data and results
are used to support the
conclusion. Some general
recommendations on how to
improve the experiment are
included without supporting
explanation.
Good
