COURSE GOALS AND STUDENT OUTCOME OBJECTIVES: Students will participate in the processes
of scientific inquiry, and will be able to demonstrate chemical facts from which chemical principles are
deduced. The student will be able to perform basic laboratory techniques and procedures. Concepts taught in
the introductory Chemistry lecture courses (CHEM 105 and 106) will be reinforced through the laboratory
experience. The laboratory is designed to develop skills that will build student confidence. Specific learning
objectives for each experiment are given in the supplements as described above
Student Outcome Objectives. At the end of this course, students will be able to
●
●
●
Use common laboratory equipment properly and safely
Maintain laboratory notebooks and write reports adhering to generally accepted scientific practices and
formats
Demonstrate a basic understanding of general chemistry principles covered in the laboratory
experiments. Specific learning objectives are provided in each experiment
Course Content The following topics will be addressed in the experiments.
● Accuracy and Precision
● Graphing Techniques: manual and computer-aided (Excel)
● Making Solutions
● Thermochemistry (Reaction calorimetry)
● Kinetics
● Acid-Base Equilibria
● Synthesis (Soap and Aspirin)
● Electrochemistry
METHOD OF EVALUATION: Your overall grade will be obtained from averaging the following categories:
Lab reports (50%), Mid-term (25%) and Final Exam (25%)
Grading scale - A= 90 - 100%; B= 80 - 89%; C= 70 - 79%; D= 60- 69%; F= below 59%.
1) Laboratory Reports - For each experiment you will submit a lab report. The report consists of the following:
Notebook pages in proper format (see below for notebook guidlines); Post-lab questions; Pre-lab
questions and assignment. Unless otherwise specified, reports are due on the next class period after
completion of the experiment. There is a 2 pt penalty for every school day the report is late.
2) Mid-term exam -written exam that consists of material over the lecture and experiments performed since the
first day of class. This exam will be given in class at midterm.
2) Final exam - written/practical exam including material from all experiments performed. This exam will be
given in class on or around last week of classes.
MAKE-UP POLICY:
NONE .You must complete all experiments. The only way to complete all
experiments is to attend lab regularly.
ACADEMIC HONESTY POLICY: Cheating or scholastic dishonesty will not be tolerated. In cases of
academic dishonesty the instructor may dispose of the matter by invoking a maximum sanction of immediate
expulsion from the course and the issuance of a failing grade. You work in groups for the experiment, but you
write individual lab reports. Similar lab reports will be considered cheating.
ACADEMIC DISABILITY POLICY: If you have a documented disability that requires assistance, you will
need to register with the Office of Disability Services for coordination of your academic accommodations. The
Office of Disability Services is located in Peltier Hall, Room 100-A. The phone number is (985) 448-4430
(TDD 449-7002).
CLASS DISRUPTIONS: Are not tolerated. The use of cell phones, pager and/or any other electronic personal
devise in class is prohibited. Any infractions will result in the dismissal from class.
CONTINUED LEARNING FOLLOWING AN EXTREME EMERGENCY:
In order to make continued learning possible following an extreme emergency, students are responsible for:
●
reading regular emergency notifications on the NSU website
●
knowing how to use and access Blackboard (or university designated electronic delivery system)
●
being familiar with emergency guidelines
●
evacuating textbooks and other course materials
●
knowing their Blackboard (or designated system) student login and password
●
contacting faculty regarding their intentions for completing the course
Faculty are responsible for:
●
their development in the use of the Blackboard (or designated) software
●
having a plan for continuing their courses using only Blackboard and email
●
continuing their course in whatever way suits the completion of the course best, and being creative in the
continuation of these courses
●
making adjustments or compensations to a student’s progress in special programs with labs, clinical
sequences or the like only in the immediate semester following the emergency.
***THIS SYLLABUS IS NOT A CONTRACT AND IS SUBJECT TO CHANGE.***
Students will be informed in class or via electronic means of any necessary changes in a timely fashion.
SAFETY GOGGLES WILL BE WORN AT ALL TIMES IN THE LABORATORY

COURSE REQUIREMENTS
LAB NOTEBOOK:
The laboratory notebook must be a permanently bound book with alternating white and yellow quadrille ruled
sheets. The yellow sheets will be used to make carbon copies of the original white sheets. The ORIGINAL
white sheets are to be handed in as the lab report.
RULES FOR LAB NOTEBOOK
a.) ALL DATA IS TO BE RECORDED IN (Black) INK DIRECTLY IN THE NOTEBOOK!!!!
b.) Label and date all entries.
c.) An error should be lined through with a single horizontal line, initialed and briefly explained.
d.) A single diagonal line should be drawn across any page that is to be ignored, initialed and briefly explained.
This includes completely blank pages.
e.) Number all pages in the notebook in the upper right hand corner of the page. The yellow carbon copies must
bear the same number as the white originals.
f.) Use page 1 for the TABLE OF CONTENTS. This should be maintained on a current basis at all times.
NOTEBOOK FORMAT - Begin each experiment on a new page.
1.) Title and Introduction (done before class)
Give the title of the experiment and a 1 or 2 sentence description of the experiment. This should be done
in your own words -- do not copy from the manuals. Important chemical reactions should also be
included here.
2.) Experimental Plan (done before class)
Provide a summary of the experimental procedure and cite the source of the experimental procedure.
Read the lab and be familiar with what will be happening. Summarize the steps; do not write a verbatim
quote of the procedure from the lab manual. You will not be allowed to perform the experiment without
this.
3.) Procedure and Data.
This section is the laboratory "diary" in which you write a step-by-step description of what you do in the
lab. Enter data as it is collected. Any observations are to be recorded here also (colors, odors,
temperature, apparatus used, amounts of reagents, etc.). Draw pictures if appropriate, use tables, graphs,
equations, etc. Record applicable details such as instrument name and maker, model number and serial
number, chemical manufacturer, grade, lot number and expiration date, etc.
4.) Calculations
Give one example of each type of calculation used in the experiment that has not been included in the
previous section. In general, this section will deal with the calculation of the final results. Be sure to
include a set-up with all appropriate units. Whenever multiple samples of the unknown are analyzed, the
average and the standard deviation (s) should be calculated.
5.) Discussion / Conclusions
Using past-tense, write a paragraph addressing the question of what was learned in the experiment. Interpret the
results and summarize the major findings of the experiment. What do the results mean? Do the findings conform
to or contradict with the accepted view? Are the results what you expected? What are the implications of the
results? What are the sources of error? What kinds of improvements could be done for future investigations?
6.) Post-Lab Questions
Be sure to answer all assigned questions. This can be source of easy points if take the time to do them. Be
specific and logical in your response.
