PHYSICS 25200 SYLLABUS Course Coordinator: Dr. Andrzej (Andrew) Lewicki - room PHYS 142, lewicki@purdue.edu office hours: T, W, Th 10:00-11:00 AM Lab Manual: Physics 21900, 22100 and 25200 Laboratory Manual, 2014/2015, Andrzej (Andrew) Lewicki, LAD Custom Publishing, 2014. Associated Textbook: College Physics Reasoning and Relationships, Volume Two, Ed. 2, Nicholas Giordano, Brooks/Cole, Cengage Learning, 2013. (Not required, but recommended) General description: Physics 25200 CRN numbers for the two laboratory sections are: 46547 and 59632. Physics 25200 is a one-credit physics laboratory course. Physics 25200 curriculum includes laboratory experiments demonstrating the following concepts: electrostatics, DC circuits, AC circuits, magnetic field, electromagnetic induction, geometrical optics, diffraction and photoelectric effect. Labs meet once per week for two hours. Physics 25200 starts with an introduction to the course and includes ten experiments plus three lab makeups. Physics 25200 experiments are identical to experiments performed by Physics 22100 students at West Lafayette campus. There are no exams for this course. The final, letter grade will be assigned based on the combined total number of points for the lab data, for answers to the conceptual questions and for the prelaboratory questions. Physics 25200 pre-requisite (or co-requisite) course is Physics 24100. In other words, you have to get a passing grade in Physics 24100 or take it at the same time as Physics 25200. Physics 25200 students will use the following lab manual: Physics 21900, 22100 and 25200 Laboratory Manual, 2014/2015, Andrzej (Andrew) Lewicki, LAD Custom Publishing, 2014. This lab manual is available from local bookstores and is required for all Physics 25200 students. Do not buy any previous editions of the lab manual as it has changed! Each experiment in the lab manual starts with a brief theory section, which contains a summary of physics concepts related to the experiment. However, students who need more in-depth information about the investigated concepts should refer to the associated 1
textbook (not required): College Physics Reasoning and Relationships, Volume Two, Nicholas Giordano, Brooks/Cole, Cengage Learning, edition 2. Physics 25200 labs meet in room PHYS 150 in the Physics Building. Lab reports are usually due at the beginning of the next experiment. For the exact dates, see the lab schedule at the end of this syllabus. Always bring a calculator with you to the lab. Do NOT bring drinks or food to the lab! Physics 25200 students have access to the same help center as Physics 22100 students. The help center is located in room 11 of the Physics Building. The help center schedule is available at the following address: http://www.physics.purdue.edu/academic-programs/courses/help_center.html CHIP main page: http://chip.physics.purdue.edu Lab procedures: Before coming to lab, you must answer all prelaboratory questions scheduled for that week. These questions are closely related to the activities and measurements you will do in lab. The prelaboratory questions typically require 30 minutes of effort. The prelaboratory questions are your individual work, so everyone is expected to complete them. The prelaboratory questions must be answered on-line using the Computerized Homework in Physics (CHIP). CHIP is accessible to any computer running popular web browser software, e.g., Firefox, Safari or Internet Explorer. Use your Purdue career account login and password to access CHIP for Physics 25200. Remember to review the theory section of each lab. If you exceed the number of allowed attempts for a prelab question, then you would not get credit for that question. In other words, no partial credit above the allowed number of attempts. All lab scores including points for prelaboratory questions (prelabs) and points for lab reports will be stored on CHIP. The prelabs of CHIP are due before the deadlines, which are set exactly at 10 minutes before the beginning of the scheduled lab time. For instance, if the lab is scheduled on Wednesday at 11:30 AM, the deadline for prelabs is at 11:20 AM on that day. After deadlines, CHIP would not assign any points for the prelabs (no credit for late prelabs). Physics 25200 students will be able to access their gradebooks (using CHIP) and check the latest scores. You will find more information about accessing and using CHIP on a separate handout available in the lab or from Undergrad Office in room PHYS 144. 2
During the two-hour laboratory period, students will observe phenomena, manipulate the lab apparatus, collect data and ask questions. Be on time for the lab. Remember to sign the lab attendance list! Your lab TA will briefly review the theory behind the experiment and describe the lab equipment to be used. Before leaving the laboratory room, make sure that your TA has initialed your data sheets. The minimum penalty for the lab reports without TA s initials is 2 points. TA may even refuse to accept lab reports without initials. During the two-hour laboratory period, you will observe phenomena, manipulate the lab apparatus, collect data and ask questions. Be on time for the lab. Remember to sign the lab attendance list! Your lab TA will briefly review the theory behind the experiment and describe the lab equipment to be used. In the Physics 25200 lab, you will work with a lab partner. In all data sheets, you will find a pair of parentheses with an empty space in between them: ( ). You are required to write appropriate unit in that space, e.g., ( Ω ). Results without units are not complete! Before leaving the laboratory room, make sure to complete all calculations, prepare the required graphs and return data sheets to the lab TA! During the week that follows each lab experiment, you should type the answers to the two Conceptual Questions located at the end of each experiment (after the data sheets). Usually, you will not find the answers to conceptual questions in the lab manual. Instead, you should search textbook, other books available in libraries and online resources. However, keep in mind that "copy and paste" method is not allowed! You are encouraged to search answers wherever you like, but you have to write answers in your own words. Simple "copy and paste" from internet will lead to a penalty. In addition to answering Conceptual Questions, you are asked to write (typed) a short discussion of physics concepts related to the experiment. Briefly describe major physics principles, concepts and formulas that were applied or illustrated in this experiments. You should write how these concepts and physics principles apply to the measurements done this week. Do not simply write a report of what you did in the lab. Instead, focus on the concept summary, i.e., the message that should be remembered from this experiment. If the experiment included testing formulas, then discuss predictions of the formula with changing conditions (for example, explain how the results would change with an increase of velocity or decrease of the moving object mass, etc.) The whole text should not exceed one page and is due at the beginning of the next experiment. Answers to the Conceptual Questions and the discussion of physics concepts are due at the beginning of the next lab and must be submitted individually by each student. 3
Grading practice: Each laboratory experiment (including prelabs) is worth 12 points. We have ten laboratory experiments (E2 - E11) in Physics 25200 curriculum (10 labs*12 points = 120 points maximum). The final, letter grade will be assigned based on the sum of your points earned for Physics 25200 (prelabs + lab reports). The letter grade scheme is based on the percentage of the perfect score: 90% (=108 points) A 100% 80% (=96 points) B < 90% 65% (=78 points) C < 80% 50% (=60 points) D < 65% F < 50% If you have missed an experiment for a valid reason (e.g., illness): Give a written documentation to your lab TA during the next lab or bring it to his office and ask permission to make-up the missed lab. If you have not turned in the answers to the Conceptual Questions from the previous lab, turn it in during the first day after your absence to the drop slot located below mailboxes between rooms PHYS 146 and PHYS 150 (make sure that your lab TA s name is written clearly on the cover page). All lab make-ups are done in room PHYS 150 (Physics 21900, 22100, 25200 lab room) at the same day and time as regular classes. Prelabs for the make-up labs must be submitted on paper during the make-up session (CHIP is not set up to handle make-ups). If you have more questions about make-ups, please ask the lab coordinator. Subtracting 1 point per school day will penalize late submissions of the answers to the Conceptual Questions and the discussion of physics concepts. Your lab TA will set the due dates for make-ups. Students are not allowed to make up more than one experiment during the scheduled lab make-up time. Re-doing labs is not possible. Make-ups are only for those who missed labs for a legitimate reason and got TA s permission to make-up labs. Prelabs for the make-up labs must be submitted on paper (CHIP is not set up to handle make-ups). Students are not allowed to copy answers, use files, or allow your answers to be copied, by any other students (except of your lab partner). Any violation of the above standards will subject the offender to penalties allowed by the Purdue University. If you wonder whether a 4
course of action violates this policy, simply ask in advance. Any attempt to forge data (e.g., copying data from previous semesters or from other students) or to forge your TA s initials will be penalized! In a case of a long illness, (e.g., two or more weeks in a hospital) you need to get permission from the course coordinator to make up the missed labs. If you have any questions concerning the lab policies, please ask the course coordinator. Keep all graded lab reports until the end of semester. After 5:00 PM on December 15, 2014, we will not accept any lab-related documents (answers to conceptual questions or physics concept discussions). 5
