                           Laboratory syllabus for CHE 141

The schedule for lab sections is as follows:

                 Section    Time     Day Location Instructor
                  Lab A  8-10:55 AM   F  HSB 328    Bapat
                  Lab B  12-2:55 PM   F  HSB 328    Morsch
                  Lab C 3:30-6:30 PM R HSB 328      Bapat
                  Lab D 3:30-6:30 PM R HSB 324 Klingshirn
                  Lab E  8-10:55 AM   F  HSB 324   Dungey

•   Make sure that you show up for your lab section on time and prepared.
•   You must follow all safety rules and regulations, there are no exceptions.
•   Pay attention to your instructor as there might be section specific information that
    they will pass on to you.

Required material:
Lab manual: “Lab Manual for Principles of Chemistry” by various authors, 2008.
Thomson Custom Publishing. Available only at the UIS bookstore.
Lab goggles: You must wear departmentally approved lab goggles while in lab. These
should also be purchased at the UIS bookstore. There are NO RENTALS available in
the lab.
Notebook: A spiral bound notebook, a black or blue pen.
Dress code: Make sure that you are properly dressed. SHORTS, MIDRIFF BEARING
SHIRTS OR TANK TOPS will not be allowed in lab. Your shoes must completely cover
your feet.
If you do not comply your instructor will send you home to change and then come back.

Preparing for the lab:
Lab will be a very enjoyable experience if you come prepared for it.
• Read the lab that you are supposed to do before you come in to lab. There will be
   UNANNOUNCED quizzes given at the beginning of the lab. Each quiz will be based
   on the material covered in the lab.
• Answer any pre-lab questions (in full sentences only) and the problem set before you
   come in and turn them in to your instructor at the beginning of lab.
• Perform only the assigned experiment in lab and clean up after you are done.
• Write (with a pen, no pencils please) all your observations in your spiral bound
   notebook and get the notebook signed by your instructor before you leave. It is your
   responsibility to get this done, before you leave. This is your rough data sheet and is
   proof that you actually showed up and did the lab.

Problem set: I will assign a problem set that you need to finish before coming to lab and
turn in to your instructor. There will be a maximum of 10 problem sets in the course of
the semester and most of these will be worth 20 points. Each problem set will be based
on the chapter/lab being covered in that week. These will be posted on Blackboard at the
beginning of the week.

Laboratory syllabus

Make-up lab:

A make-up lab section (only for those students who miss a lab and have a valid excuse)
will be offered, most probably on Monday afternoon. The make-up section will be
offered only once. If you can’t make it to the make-up section you will receive a grade of
zero for that lab.

Lab report:

It is quite important to be able to summarize and report the results of any experiment that
you perform and to draw well informed conclusions from your experiment. The purpose
of the lab report is to achieve just this. You will have one week to complete your lab
Even though you will be working with a lab partner, each of you needs to write his/her
own lab report. Here is what I expect all of you to have in your lab reports:

•   A cover sheet with your name and your lab partner’s name, the title of the
    experiment, the date the experiment was performed.
•   Your lab report will consist of the following sections with the section headings;
    Introduction, Procedure and Conclusions which must be typed using common fonts
    such as Times New Roman and a size of 12. Give each section a heading and make it
•   Please write these sections in the past tense and in the third person. Avoid using
    words such as I, our, we etc. For example; instead of writing “I weighed a sample of
    copper wire on an analytical balance”, write “A sample of copper wire was weighed
    on an analytical balance”.

Introduction: In your own words describe what you learned by performing this
particular experiment. Do not simply repeat the title of the experiment.
You may address key skills learned, concepts from lecture that are related etc. At the
most half a page of single spaced information will be sufficient here.

Procedure: You may write the following sentence and then write any modifications
(additions/subtractions) made as necessary.

       The procedure for the experiment “Determination of density” from the lab manual
       for CHE 141 was followed.
       There were no modifications made to this procedure.

Conclusions: In this section which will be of a reflective nature you should address how
doing the experiment helped you understand the underlying concepts or how you learned
new techniques or new ideas. Don’t just summarize your results here.

Print and staple all the pages together.

Laboratory syllabus

 • This will constitute a complete lab report which will be graded out of 20 points.
   Include your data sheet, results sheet and answer all post-lab questions. Do not forget
   to include your signed rough data sheet.
 • Make any graphs in Excel®, print and attach them to your report.
 • For all post lab questions you may use the space that is provided on the sheet and
   write your answers neatly in complete sentences. If you wish to answer these
   questions on a separate sheet of paper there is no need to rewrite the questions.

Lab Sequence for CHE 141

All of these labs are hands-on labs where you will perform these experiments in our labs
using the necessary equipment, chemicals and glassware.
