The first meeting on Monday will consist of a lecture. The second meeting on Friday will be entirely dedicated to the lab. The lab experiments are quite extensive and time consuming. Attendance and arriving in time will be mandatory for the class. There will be no eating or drinking allowed in the class. Students must make an effort to keep their workspace clean and organized. Students failing to clean up after themselves will be penalized on their lab reports after a verbal warning from one of the TAs or instructor. Experiments will be conducted in groups. There will be two-three students per group. Students will take data in their groups; however, each student must turn in individual reports. It is strongly recommended to write the reports separately to avoid the temptation to copy and paste a partner’s report. Reports that are found to be near verbatim copies of one another will be considered as plagiarized and both students will face severe consequences. These can range from failure of the assignment, failure of the course, and for extreme cases dismissal from the university. Lab reports will be quite different from the reports that were required in previous physics labs. Physics 482 is designed to not only imbue the student with the ability to apply experimental techniques to problems on their own, but to teach them how to write in a concise manner about scientific matters. Reports must be typewritten, double spaced, and in 12-point font. A small portion of each lab grade will depend upon spelling and grammar. Errors such as these are inexcusable and would look quite unprofessional in the workplace. Graphs and plots must be done using the analysis framework taught (ROOT) or similar computing software, and must follow the provided format. Hand-drawn plots will not be accepted. A detailed report format guide is provided in this manual. The report format and guidelines are not negotiable and will be strictly enforced. Laboratory Report Format Lab reports are to be a professionally written with proper grammar and no spelling errors. Modern word processors have excellent spelling and grammar checkers. However it is still a good idea to read through your report and not trust what your program tells you. Variables and parameters must be italicized and an equation editor such as MS Equation is mandatory for reproduction of formulas in the report. Do not handwrite equations in your report. Each report must contain a separate cover sheet stating the following: name, partner’s name, experiment title, and date. The lab reports will contain six specific areas: an abstract, history, introduction, results & discussion, a conclusion, and references. Attendance: Attendance is compulsory. Common sense dictates that data cannot be taken if the student does not show up to class. Coming late to the class for every 15 minutes on Monday or Friday will result in losing 10% of the full points for that experiment. Missing the class on Monday (Friday) will result in losing 30% (70%) of the full points for that experiment. The instructor reserves the right to require you work on your own or deny your access to the lab should you arrive too late to the class. Abstract (5%): The abstract will be a brief statement that informs the reader about the contents of the report. What did you do? Why did you do it? What are your most important results? The abstract should be no more than five sentences long. Introduction (15%): What is the context of the report with respect to the class? Describe the situation that you are examining either experimentally or computationally. Start with a figure of your experimental set up. Use a paint program to design the figures. Hand drawn figures are not acceptable. Describe the details of the figure and add material as needed to aid in the reader’s grasp of the system, actual photos of the set up work well here. Describe the equipment in detail. What is the model number of the system, who makes it? Include the specifications of the equipment (power, wavelength, etc.). Describe the theoretical basis for the experiment. Develop the appropriate equations, explain the symbols contained in each equation. Do not simply quote the equations. Important equations should have an equation number. Equations should always be part of a grammatically correct sentence. Results and Discussion (50%): Provide a detailed discussion of what was actually done during the experiment. This does not mean a laundry list of steps. As with the other sections, the results and discussion section must be written in paragraph form. If data can be included in a table within this section, do so. Otherwise larger, more extensive data tables can be attached to the report as separate pages. Include discussions of properly formatted graphs. A good way to start writing this section is to produce the graphs that you need to explain the importance of the work, and then write a paragraph about each graph. If you have many similar plots describe the differences and similarities between them. An uncertainty or error analysis is usually included in this section of the report. The uncertainty analysis is not a list of all of the mistakes that were made in the laboratory. If mistakes were made, then the proper procedure is to go back and do the laboratory over. Rather, the uncertainty analysis is where you provide quantitative arguments about the quality and validity of your results. A very instructive way to do the uncertainty analysis is to consider how certain you are of each individual measurement that is used in determining final results. State the basis for each of the individual uncertainties. Never use human error. Mistakes are not uncertainties. Then explain how the uncertainty in each individual measurement impacts the uncertainty in the final results for the laboratory. There are other, often statistical, methods for doing an uncertainty analysis. While other methods might be more traditional in the professional literature, they also assume the author has a detailed understanding of the statistics. The method that is suggested here will help you better understand the statistical methods when you encounter them. Conclusion (20%): A conclusion should never include comments about whether you liked or disliked the experiment. It is not a summary of the report as a whole. It should include your important numerical results (compare this to most important numerical results in the abstract). It may also include qualitative results. References* (10%): This section will include the references you used in the introduction section. Books and journal articles must be reported using the proper format. *Notice For Electronics Lab Reports, Results and Discussions are 60%. You don’t need References. Graph Format As stated previously all plots are to be created using the ROOT framework or similar computing software. Plots should be readable: labels are to be made with at least 12-point font. Each plot must contain an appropriate title (Current vs. Voltage). The axes must be labeled appropriately with proper units (Current (A), Voltage (V)). The independent variable must be situated on the x-axis. A good example of a properly formatted plot can be seen below. Laboratory Equipment It is important to keep your workstation neat and orderly. Be sure to turn off all electronics you used during the lab and to return all equipment back to the place where it belongs. Any student found guilty of wanton negligence or abuse of lab equipment (such as leaving an oscilloscope on, touching equipment that we are not using in lab, blowing circuits on purpose, making hazardous circuits, etc.) will be removed from the class. THIS IS YOUR OOPORTUNITY TO LEARN HOW TO PROPERLY USE THE SKILLS AND TOOLS OF YOUR CHOSEN FUTURE PROFESSION. Laboratory Reports The students will be required to complete reports for all the electronics labs, advanced physics labs, and final project. The reports will be due by 12:00pm on FRIDAY the next week after the completion of the experiment, either in Prof. Ye’s mailbox in Physics Main Office SES 2236 or by email to Prof. Ye. Reports that are turned in late will lose 15% of the full points for each additional day (including weekends) that the reports are late, after the total number of days being late for all the turned-in reports exceeds 14. One project will be chosen to include also an oral presentation, to be done during the week of May 4-8 and must be approximately thirty minutes in length for each presentation (24 minutes for the oral talk, and 6 minutes for Q&A). A laptop and projector will be provided. Grading Policy Laboratory report and presentation grades will be basis for the course grade determination. A single letter grade of A, B, C, D, or F is assigned at the end of the semester according to the total score each student has earned. The relative weights of the lab reports, final exam and presentation are: report for electronic lab 1-5: 6%; report for 1-week advanced experiment 1-2: 8%; report for 2-week advanced experiment 3-5: 10%; presentation: 12%; exam: 12%.
