Course Material Fee
To off set the cost of expendable items of the Physics 111B-Lab course, students of the Physics 111B-Lab must pay a Course Materials Fee (CMF) of $165.00 (now $175). CMF is a kind of fees approved under the authorities contained in the policies of the Office of the President (October 2014) and the Berkeley Campus (October 2009). The fees are assessed after the fifth week of classes in Fall and Spring, and will be included in the students' CARS (Campus Accounts Receivables System) statements.
The goal of the advanced lab is to become familiar with experimental physics research. It is a test run as an experimental physicist with all responsibilities. This includes learning how to conduct meaningful experiments, mastering important experimental instrumentation and methods, analyzing data, drawing meaningful conclusions from them and presenting your results in a succinct manner. For this, you will conduct four experiments chosen from 19 other experiment in the lab and one error-analysis exercise. Every student must complete the Optical Pumping experiment.
Important note: if you repeat this class (including dropping it), you must talk to an instructor about which experiments you should choose. Repeating experiments you have done in a previous semester is not allowed.
Note that there is NO eating or drinking in the 111-Lab anywhere, except in rooms 282 & 286 LeConte on the benches with the BLUE Stripe around it. Thank You from the Staff.
Learn how to think as an experimentalist
What am I trying to find out? Why?
What does my experiment do? What piece of equipment does what? How?
How precisely/accurately do I need to know something in my experiment?
What aspect of my experiment and of the background physics is central, and what is peripheral?
How trustworthy is my measured result?
What might have caused statistical errors in my measurement? What might have caused systematic errors in my measurement? How can I honestly and convincingly estimate the effect of those errors?
Learn how to communicate science
There will be a lot of hard work and frustration, but it is a very rewarding experience, and worth the effort. Often there is no satisfactory solution to a particular problem. Thus you will not be penalized for not getting the correct answer, rather your grade will depend on how systematically you approach the tasks and solve the inevitable problems. The lab is equally challenging to the teaching staff who may not be familiar with all the experiments. Note that the goal of this course is not to teach you the right answer but to instruct you how you can figure out the answers. We are here to help and to guide you in this process. We will teach you problem-solving strategies, for instance, by asking questions rather than giving you the answer you might actually seek.
What you do in this course
Complete 5 assignments (1 EAX exercise, 3 written, 1 oral report) to receive a grade in this course.
EAX: Error analysis exercise
Look for assignment and background materials online
Please read one of the recommended texts on statistics. It will help you immensely in the long run. Do not just be a “write-up reader.”
Complete problem set
- Choose and sign up with your full name for a time slot on an experiment
Read lab manual and background materials, watch videos, go over pre-lab questions before coming to class, look at the apparatus before your first assigned day.
Present the Pre-lab before first day with GSI or Prof. Mid-lab sometimes.
Written reports must be submitted on the due date. Oral report is given to a faculty at your signed-up time slot after the due date.
There are about 20 experiments available for this semester, covering a wide range of fields in Physics, such as atomic physics, condensed-matter physics, optics, nuclear and particle physics. Each experiment has instructions accessible via the navigation bar at the top of the web site but refrain from using them as a recipe. You will be much better off by understanding what you are doing rather than following instructions. You must do four experiments and the exercise on error analysis (the latter in the first week of class) to complete the course requirement. One of the four experiments must be Optical Pumping; The other experiments are divided into two groups based on their overall effort. Please note also that we will take the level of difficulty of the individual experiment into account when we grade; in particular, we expect you to go into much more detail for the "easy" experiments.
You can sign up for the first experiment on the first day of class. For the following labs, we will announce a day from when on you can sign up for the next experiment. Sign up will be by groups as determined on the first day of class. The order of the group will rotate through so that every group will have a good chance to choose at least once their favorite experiment.
In Fall 2018, we have the following sign-up days and orders:
lab #1: August 22 for groups A (1 pm), B (3 pm). August 23 for groups C (1 pm), D (3 pm)
lab #2: September 4 for groups B (1 pm), C (3 pm). September 5 for groups D (1 pm), A (3 pm)
lab #3: September 25 for groups C (1 pm), D (3 pm). September 26 for groups A (1 pm), B (3 pm)
lab #4: October 16 for groups D (1 pm), A (3 pm). October 17 for groups B (1 pm), C (3 pm)
- You perform experiments with a lab partner. You work together on the experiment. However, the main part of your data analysis and all or your written/oral report must be your own work.
- You must sign up to do an experiment in one of the assigned slots. You cannot split your time between multiple slots. The sign-up list is in LeConte 286 next to the door.
- You sign up for Lab 1 on the first day. You sign up for later labs on later days (it will be announced).
- You sign up by sign-up groups see above
- Some of you will have to start Lab N before turning in the report for Lab N-1.
- If you turn in EAX or a lab report after its due date, you will incur a late penalty.
Reasons for failing this course
- The main reason for failing this course is lack of time management resulting in not turning in all reports and/or too many late penalties. A late report will likely mean that the next report will be also late as you will be busy writing the already late report. So please avoid turning in reports late; it does not pay off.
Preparation for each experiment
- Prepare to do the pre-lab at least one day prior to starting your experiment. Otherwise you might loose valuable experimenting time.
- Download the write-up of the experiment from the wen site page.
- Read some of the references and the write-up.
- Watch the appropriate videos for the experiment and any lecture series or safety videos that are available. Attention: some of the videos may be out of date and the apparatus and the procedure may have changed. However, the key is to learn the concepts and experimentation.
- For some experiments, either a laser or radiation safety training is required. Take the required training course and the quiz.
The pre-lab questions are there to help you to identify the most critical concepts for successful experimentation. Use them as a guide of what to read about. Prepare to answer the pre-lab questions orally in the lab. Do not hesitate to contact the staff in the lab if you encounter difficulties with the subject. We might not answer your questions directly but we will help you to find the answers. The better you can describe your problems, the better we can help. Thus: think and discuss among yourselves first before you ask.
In the Laboratory
For successful experimentation, you must have a good understanding of the underlying physics. The pre-lab questions are there to guide you towards the important concepts and we require you to go over them with the teaching staff before starting to do the experiment. You do need to turn in and show your written answers to the pre-lab questions. You must demonstrate a sufficient understanding of the physics related to the questions, otherwise you will not be allowed to start the experiment.
- Get familiar with the apparatus.
- Ask yourself questions before taking any action.
- Be patient and careful. Safety is essential.
- DO NOT ABUSE any piece of equipment.
- If there is any issue, talk to the teaching staff or Win.
- You must be proactive when working together.
- Plan ahead: take some measurements and quickly analyze the data to get some idea whether you are heading in the right direction, then take more data.
You must complete one oral report per semester on an experiment see Oral Report Guidelines and view the How to do an Oral Report Video. All other reports are in written format (see Written Report Guidelines).
All written reports must be submitted online through Bcourses.
Oral report (20 minutes presentation + ~10 minutes questions)
- You must give only one oral report for one of the first three labs.
- You must sign up for which lab you will do the oral report during the first week(s) of the semester.
- Watch the video on how to prepare an oral report.
- Hand in the signed pre-lab page and show the faculty instructor copies of your data and analysis.
- You can either use the white board or any kind of software tool for presentation.
- 10 points will be deduced for every 10 minutes late for giving your oral report.
- While we expect a coherent and well-structured presentation, be prepared that questions wil be discussed as they come up during your presentation.
Written report (less than 15 double-spaced pages): Note All reports must be submitted online through Bcourses.
Please read here: http://experimentationlab.berkeley.edu/ReportGuidelines
Some advice on writing the report:
- Latex is a free powerful word processor that is popular among the physicists and mathematicians. Thus, we encourage you to use it to write your report, but we accept any reasonable format.
- We encourage you to analyze your data with MATLAB which is available in the lab; otherwise consider Octave or Python as an alternative to MATLAB. Excel for performing fits is strongly discouraged.
- You don't need to provide long derivations.
- You should cite references in the text. For example, to cite a paper: J. Last, Phys. Rev. Lett. volume number, page number (2013); to cite a book: J. Last, title of the book, page, publisher (2012).
- Your should only provide relevant information: think what a student in your position needs to know to understand what you did.
If you encounter difficulties with the analysis or physics, do not hesitate to contact the staff in the lab; we are there to help you.
Use common sense and think before acting.
- No food or drink is allowed in the lab except for the specified area marked with blue tapes.
- Some experiments that use radiation or lasers will require safety training.
- View the Radiation Safety Video on YouTube. Then get a pink Radiation Safety form from a 111-Lab staff person. Fill it out & sign the form for getting a Radiation Ring. Also, complete the Radiation Safety Training. After completion of the training, turn in all forms to Winthrop Williams or teaching staff.
- View the Laser Safety video here.
- Complete the read and sign laser training Laser Safety Training
- Spill of any chemical see the Chemical Data Sheets Campus MSDS;
Any Questions contact Lab Staff and or call EHS 642-3073 between 8AM and 5PM after hours
call from cell UC Police 642-3333 or 911 from campus phone
Your final semester grade will be determined from the total points you receive for the reports where we will take the difficulty of each experiment into account. Each of the four lab-reports is graded on a 0 to 100 point basis, while for the error analysis report you can receive up to 50 points. There are many factors that go into determining the grade that a report receives, but we offer the following rough grading guidelines, where >50% is considered a passing grade:
- Excellent (80% - 100%): Student completed most parts of the experiment, and report demonstrates a clear understanding of each part and the overall picture. The report is easy to follow (would be clear to another student), and is complete without being padded. Report contains complete error analysis, and contains no or few mistakes.
- Average (60% - 80%): Student completed most parts of the experiment, and report demonstrates a general understanding although student may appear confused over some points. Analysis is difficult to follow, and conclusions drawn from the data are not clearly stated.
- Poor (40% - 60%): Student completed major parts of the experiment, but fails to draw conclusions from the data. Report is difficult to follow, and contains many errors.
- Insufficient (0% - 40%): Student fails to demonstrate an understanding of what the experiment is about and/or major parts of the report are missing.
You must have given an oral report. Remember that students who are missing work will be assigned a grade of "F" for the semester, and that no report will be accepted after the last due date.
Note also that you must have turned in all four reports and the error analysis report by the deadline of the last report.
Pick up your report in the lab. We try to return your graded report in a timely fashion, i.e. in two weeks. For feed-back on presentation style, we encourage you to go through the report together with the GSI/faculty who graded it.
10 points will be deduced for every 10 minutes late for giving your oral report at your sign-up time. All written reports are due by 11:00 pm except the last one on the due date. Ten (10) points will be deduced for each started week past the due date. No report will be accepted past 08:00 am on the due date of the last lab report, no exceptions. Getting a late start on your report is no excuse for turning in the report late.
Both the University and the 111 Lab staff take the subject of plagiarism very seriously. Please make sure you understand completely the following and ask questions if ever in doubt: "All data that you present in your reports must be your own. All written work that you submit, except for acknowledged quotations, is to be in your own words. Work copied from a book, webpages (including the experimental instructions), from another student's report, or from any other source without proper citation will, under University rules, earn the student a grade of 'F' for the semester, and possible disciplinary action by the Student Conduct Committee." Note that a proper citation requires that you mark clearly which text/illustration has been copied from as well as the source of it. This is most easily done by adding a note of the form "Illustration taken from Ref. [<number>] below the illustration indicating which reference this excerpt belongs to. In case you quote a text, put the quoted text in quotation marks and add the reference number after the text.
You will probably take your data with a partner, and may work together on analyzing these data. But each person must write his or her own report and submit it to 111-Lab Staff for grading. The text of your report, graphs, figures, and derivations of equations must be your own. (This includes graphs generated using standard software: you must each make your own). Please be sure to acknowledge any sources that you use in your reports, and be careful not to copy another's work.
End of the semester
All materials and reports are due by the last due day, no exceptions. Any graded Lab Reports not picked up by the first week of the subsequent semester will be thrown away. Please make sure you return your radiation ring if you use one. Please let us know how we can make improvements by completing the course evaluation at the link
