Grading and Notebook Policies
Professor Forrest
Your grade will be based on a 1000 point scale broken down as follows:
Lab Reports
Pre-Lab Assignments
Lab etiquette/practices
= 600 pts.
= 140 pts.
= 260 pts.
1000 pts.


There will be a pre-lab assignment each week. Come prepared!
Unless otherwise noted, lab reports will be worth 50 points each and pre-lab assignments
will be worth 10 points each.
Lab Etiquette/Practices
Each week you will be graded on your overall work in the laboratory and awarded a score out of
20 points. Some of the ways you can lose points are as follows:






Repeatedly not wearing safety goggles.
Making a mess and not cleaning it up.
Careless or unsafe practices.
Pouring chemicals back into the
bottles.
Leaving equipment or chemicals out.
Misuse of the balances and equipment





Breakage of eqipment or glassware
Not returning your drawer key.
Showing up late.
Showing up dressed improperly.
Not coming prepared for the
experiment.
Lab Reports
1. Pre-Lab exercises are due when you come to lab. If it is not done by the beginning of lab
or you are late, you will receive no points for the pre-lab. However, I may still require
that you complete it before beginning the experiment. All pre-lab assignments should
also be turned in with the completed report so the score can be added to the report total.
2. Lab Reports are due the same day, before you leave lab, unless otherwise stated.
3. Keep it neat and orderly. If I have difficult time finding or reading the information in
your report, you will lose points. If you make a lot of mistakes in your writing, do not
write in pen. Use a pencil instead.
4. Organize the data and calculations in an easily read format. That often means tables.
5. Include units with all numerical data and calculated values.
6. Record all numerical data to the proper number of significant figures. Use all the
precision your equipment will allow you.
7. Show all calculations clearly! If you need to perform a series of the same calculation on
repeat trials of the same measurements, you only need to show one calculation and the
results from the rest.
8. Explain your answers and write in complete sentences when answering discussion
questions.
9. When making observations be as specific as possible. Answer the questions –Where?
When? and What? Simply stating “It turned blue” is not sufficient. A better observation
would be, “The solution turned blue instantly upon adding the hydrochloric acid.”
10. In some cases you will be asked to write out your procedure. Be as specific as possible
as to what actions were, or are to be performed. I should be able to read your procedure
and repeat exactly what you did.
11. DO NOT write on ANYTHING other than your lab notebook pages. Do not record data
anywhere else. Do not write calculations, procedures, or observation on another sheet of
paper first and then copy them into your lab report. If I catch you doing this I will take
away the paper and you will lose 10 lab practice points.
Absence Policy
You are expected to attend ALL the labs. At some point this semester something may arise, such
as an illness, that may result in you missing lab. If this should happen, talk to me a soon as
possible. If it is an excusable absence, than a makeup time for the lab will be scheduled. If this
is not possible than other arrangements will be made so that you will not get a zero for that
particular lab.

Absences require a doctor’s note or other documentation verifying the reason for your
absence.

If the absence is not excusable or you fail to talk to me about it, than you will receive a zero
for the lab report that you missed.

Performing an experiment at a time other than your regularly scheduled lab time without my
permission will result in an unexcused absence and a zero for that experiment

Should you miss lab for any reason and not make it up, you will forfeit your lab practices
grade for that experiment. Should you make up the lab with another instructor you will lose
½ of your pts because I cannot witness your performance.

If you miss more than 2 labs for any reason you may receive an F in the course.
