Syllabus Outline
Students enrolled in Physical Chemistry I are, for the most part, junior or senior level chemistry majors. The laboratory section of this course will be presented at a level consistent with an upper-division course designed to allow students to develop expertise in experimental physical chemistry. The experiments chosen are not primarily concerned with "techniques" per se or with the analytical aspects of physical chemistry. Rather, they are chosen (1) to illustrate and test theoretical principles and (2) to help students develop a research orientation by providing basic experience with physical measurements that yield quantitative results of important chemical interest. The course is considered "writing intensive" in that great emphasis is placed on students’ ability to communicate the results of their experimentation in the form of formal laboratory reports.
Chem. 3119 is the first-semester laboratory section of a two-semester sequence in Physical Chemistry and represents an introduction to experimental physical chemistry. Emphasis will be placed upon communication of results and the use of computers in analyzing data. Formal laboratory reports, wherein students must demonstrate an understanding of the principles behind each experiment and explain clearly the results of their measurements when compared with expected values, will be required for each experiment. At the conclusion of this course, students should be able to produce a competent, formal laboratory report, correct in both English grammar and scientific content.
The outcome will be evaluated by the quality of the last two laboratory-reports turned in by students near the end of the semester after the preliminary reports have been graded and the results discussed with the students. This gives students time to correct their procedures and get over any initial writing blocks.
A tentative laboratory schedule is given below with suggested dates on which specific experiments should be performed and laboratory reports submitted. Generally, a four-hour laboratory period is assigned to complete one experiment, although in some cases more time may be required to finish collecting data. Some laboratory periods are designated laboratory-lecture periods where laboratory results are discussed and preliminary laboratory reports are checked. The finished laboratory report will be due approximately two (2) weeks after the laboratory experiment.

The laboratory sessions meet once a week on Wednesday from 2:00 p.m. to 6:00p.m., with the first 50-minutes or so reserved for a laboratory lecture, if needed. Generally, one period will be devoted to collecting data for the experiment and the next period will be devoted to laboratory reports. Students will have two (2) full weeks to submit the finished report and must have preliminary reports available on laboratory-lecture day.
This course is writing-intensive by design. The semester grade is based largely upon the laboratory reports submitted by the student. These reports can be very time consuming and may take up to 20 clock hours to finish. Students are advised not to wait until the night before a report is due to start writing the report. Generally, students will be given two (2) weeks after an experiment has been performed to turn in the completed report. Reports will be accepted up to one (1) week late for half-credit. Zero credit is granted for reports more than one week late.
Department tutors are available during the regular semester in W-105. Their schedules are posted outside of the room. Note that tutors are not very useful for laboratory courses.
There will be no intra-term tests, but students should be prepared for a final examination that is based upon one of the experiments conducted during the semester. One scenario involves providing the students with simulated data from one of the better grasped experiments
The Howard Payne University attendance policy as outlined in the Student Handbook and in the University Catalog states that a student cannot receive a passing grade in a course unless attending 75% or more of the scheduled classes or labs. Students in this course are expected to attend every laboratory session, whether a laboratory lecture or an experiment is scheduled.
Laboratory reports will not be returned to students after they have been graded in order to eliminate "fraternity" files. Graded reports will be discussed with students on an individual basis to correct any mistakes in the reports.
Students who repeatedly violate safety regulations which violations in the sole opinion of the instructor make them a danger to themselves and to other students working in the laboratory will not be allowed to continue in the laboratory. Cheating will not be tolerated in any form. All laboratory reports must be a student's own work, even though laboratory partners may have helped in the collection of data. Students should be totally familiar with the academic and personal integrity statement in the Student Handbook for details.

Emphasis will be placed upon communication of results and the use of computers in analyzing data. Formal laboratory reports will be required for each experiment in which students must demonstrate an understanding of the principles behind each experiment and explain clearly the results of their measurements when compared with expected values. At the conclusion of the course, students should be able to produce a competent formal laboratory report that is grammatically and scientifically correct.
Students are to take the American Chemical Society (ACS) Physical Chemistry examination at the end of the second semester (CHE 3321 & CHE 3129). The scores on this examination, as compared to the nationwide percentiles, will be used to help evaluate the intended purpose and outcome of this course.
Credit form Chemistry 3311, Physical Chemistry I, the lecture section Students dropping Chemistry 3321 before the end of the semester must also drop the laboratory, Chemistry 3129.
A tentative laboratory schedule is given on below with suggested dates on which specific experiments should be performed and laboratory reports submitted. Generally a four-hour laboratory is assigned to complete one experiment, although in some cases more time may be required to finish collecting data. Some laboratory periods are designed laboratory-lecture periods where laboratory results are discussed and preliminary laboratory reports are checked. The finished laboratory reports will be due approximately two (2) weeks after the laboratory experiments.

The laboratory session meet once a week, on Wednesday, from 2:00 p.m. to 6:00 p.m., with the first 50 minutes or so reserved for a laboratory lecture, if needed. Generally, one period will be devoted to collecting data for the experiment and the next period will be devoted to laboratory reports. Students will have two (2) full weeks to submit the finished report.
This course is writing intensive by design. The semester grade is based entirely on the laboratory reports turned in by the student. These reports can be very time consuming and may take up to 20 clock hours to finish. Students are advised not to wait until the night before a report is due to start writing the report. Generally, students will be given two (2) weeks after an experiment has been performed to turn in a completed report.
Dr. Smith is available according to the schedules posted by his office door.
The bulk of the term grade is based upon the reports presented at the conclusion of each experiment. Each student will be graded upon his fulfillment of the assigned role during the course of the experiment. Therefore, there is no certainty that all students will receive the same grade for a given experiment. Each student’s efficacy will be assessed by personal observation and polling among the members of the group. A final examination that reviews the principles and techniques investigated will be given in accordance with the Final Examination schedule.
1. course grade
The semester grade will be determined using the following weighted sections:
|
Laboratory Reports |
75% |
|
Final Examination |
25% |
2. laboratory report
a) title page and abstract.
The front page of the report should display a title, name, name of laboratory partners, date report submitted, and an abstract. The abstract is typically 50 to 150 words long and should summarize the results of the experiments and state any significant conclusions. Numerical results with confidence limits should be included.
b) introduction
This section should state the purpose of the experiment and give a very brief outline of the necessary theory. The introduction should be as concise as possible—between 100 and 300 words.
c) experimental method
This section is usually brief and merely cites the appropriate references, which describe the details of the experimental procedure. A summary statement or condensed derivation of the phenomenological equations used to analyze the raw data should be given. A statement of the number of runs made and the conditions under which they were carried out should always be included at the end of this session.
d) results
This section should present the experimental results in full detail, making use of tables and graphs where appropriate. No result should be excluded merely because it is unexpected or inconsistent with other data or theoretical models. If one or more computer programs have been used in processing the data, they should be cited in the reference section. If appropriate, provide a complete listing of the program in an appendix.
e) error analysis
An error analysis dealing with the uncertainty in the final results due to random errors in the measurements will normally be part of the results section. Because of the emphasis in this course on data analysis, Error Analysis could be summarized in its own section. The type of error analysis undertaken will depend a great deal on the nature of the experiment.
f) discussion
This is the most flexible part of the laboratory report, and students must depend heavily on their judgment for the choice of topics for discussion. The final results of the experiment must be clearly presented. A comparison, often in a tabular or graphic form, between the results and theoretical expectations or experimental value from the literature should be made, and any discrepancies must be commented upon.
g) references
All outside references must be cited in this section. Students who look up a value in a handbook, for example, must cite that Handbook as the source. Two sources that must be cited in the report are the laboratory textbook and the lecture text.
The Howard Payne University attendance policy as outlined in the student handbook and in the university catalog states that a student cannot receive a passing grade in the course unless attending 75% or more of the scheduled classes or laboratories. Students in this course are expected to attend every laboratory session, whether a laboratory lecture or an experiment is scheduled. It is possible, however, for students to perform an experiment, i.e. collect data, on a day other than Wednesday with the laboratory instructor's advance approval. The only criterion in this case is that the laboratory report must be submitted on time, i.e., the date given on page 2 of this syllabus.
Since all students are expected to record observations and write reports in the laboratory notebook, all work will be recorded and retained by the students at the conclusion of the semester.
Students who repeatedly violate safety regulations, which breach in the sole opinion of the instructor makes them a danger to themselves and to other students working in the laboratory, will not be allowed to continue in the laboratory. CHEATING WILL NOT BE TOLERATED IN ANY FORM. All laboratory reports must be a student’s own work, even though laboratory partners may have helped in the collection of data. Students should be totally familiar with the academic and personal integrity statement in the Student Handbook for details.
