Physics II Laboratory Grading Rubric for
Written Reports (5 required). Each experiment will be tallied for
a total of
100 points. Spring 2010
[Note: If a student fails to submit any lab report in a period
greater than 4 weeks one less lab report will be allowed.
DESCRIPTION OF THE EXPERIMENT. 30 points.
Clearly identifies the purpose of the experiment. This should be written in clear, succinct
prose. Use first person or third
person, but should be consistent
- what is being tested?
- what results are predicted?
- discusses the tools and equipment
- uses clear diagrams
- sets the tone of writing for one's
EXPERIMENTAL RESULTS. 40
- Results are presented in clear,
well-labeled graphs. Most experiments use
computer-generated graphs. The computer
generated graphs should have appropriate scales on the axes, points
plotted as a scatter plot with no connecting lines (unless appropriate
to show continuity), a trend line shown when appropriate.
- Appropriate use of the trend line. Sometimes the trend line is inappropriate and
has no relevance to the experiment and should not be included.
- Appropriate use of simple tables. Raw computer data should not be presented in
extensive tables. When tables are used,
the tables should be small and concise and serve to provide a short
summary of the data.
- Calculations should be demonstrated
with a sample calculation. The
calculations may be hand-written, but it is possible with a little more
effort to show the formulas and calculations with an equations editor
on the word processor.
- Units and dimensions should be shown
and correctly derived.
DISCUSSION OF THE RESULTS (this is
often the most difficult part of the report). 30 points.
- The significance of the results is
clearly presented. It basically answers
the purpose of the experiment or why the experiment was done
- The results are compared with the
predictions made before the lab
- Numerical results are presented in a
simple table along with percent differences fom published
results. A comment should be included on the quality of the
results based mostly on the percent differences
- The student clearly explains what she
or he has learned by doing the experiment and that the student
understands the principles presented in the graphs
- The report is basically free from
grammar errors, spelling errors (use of a spell-checker and peer
proofreading is encouraged). Sentences and
paragraphs are succinct and free from run-on errors.
- The report
communicates the physics and the student
clearly shows an understanding of the physics in the whole report.
