All assessments submitted late without legitimate cause (see Section 3.3) will be penalized 10% per late day, to a maximum of 50%. After five days, the late work will no longer be accepted and the student will receive a grade of 0 for that assessment.
Section 3.1.1: Lab Notebooks
Students will submit their lab notebooks on the Wednesday (by 4:30 pm) following each experiment week for your group. Notebooks will be evaluated based on the criteria described below, and will be available for pick-up on the following Monday during scheduled lab time. Students are encouraged to keep two separate lab books to allow the GTA sufficient time to grade the lab books. Students may continue to use their lab notebooks from PHYS*2180.
Students should be writing in their lab notebooks as they perform the experiment. Students will be assessed using the following criteria:
1. Materials & Methods (8)
- briefly describe what was done as it is done – you should be able to reproduce the procedure from the notebook without the lab outline!
- logging experimental conditions
- data recording
- dates, run times, file names, etc.
2. Results & Analysis (12)
- raw data (where applicable) and quality of that data
- graphs and brief discussions of the data
- questions asked in the lab outline, including derivations
3. Clarity (2)
- notebook should be legible and reasonable and easily navigable
Please note that your lab notebook does not require a detailed motivation/introduction section for each experiment. A summary of the key points is generally sufficient, however questions in the lab outline should be addressed and derivations should be completed. Much of this work can be done before you begin your experiment! If you are completing your notebook properly, you should only need to generate graphs, perform some calculations, and provide a very brief discussion of the data after the experiment.
Section 3.1.2: Formal Lab – Science Paper
Each student will hand in two written formal lab reports, written in the style of a scientific paper. Formal lab reports are due in the Courselink Dropbox by midnight on the due dates given in the course timetable (see Section 5.1).
Evaluation of the science papers will be based on students’ ability to properly motivate the experiment that was performed, to interpret and discuss their experimental data while using proper scientific writing styles, and to properly discuss experimental limitations within accepted error analysis frameworks. Spelling and grammar will be assessed in these reports. In general, your science papers should not exceed 6-8 pages (1.5 line spacing) for most experiments. Students will be assessed more heavily on the merit of their scientific arguments than was done previously in PHYS*2180.
You cannot submit science papers for experiments that have been submitted as posters – it is a good idea to coordinate with your lab partner!
Section 3.1.3: Formal Lab – Poster (First Draft)
Each student will produce a scientific poster (48” wide by 36” high) summarizing the results of one of their experiments. This poster will be submitted electronically as a PDF document via Dropbox by 4:30 pm on Wednesday, March 14th (Group A) or Wednesday, March 21st (Group B). The poster draft will be assessed by a Teaching Assistant that will provide useful feedback before the final posters are printed to be presented in Week 12. Students are encouraged to browse the scientific posters found throughout the MacNaughton building for guidance. A good principle while designing your poster is to maintain a balance of roughly 30% text, 30% visuals, and 30% empty space.
You cannot submit a poster for experiments that have been submitted as science papers – it is a good idea to coordinate with your lab partner.
Section 3.1.4: Formal Lab – Poster (Presentation)
After feedback has been received, each group will print their posters (this typically costs $30-$40) and present them to their peers in a PHYS*3510/4500 Poster Session scheduled on Monday, April 2nd from 2:30 – 5:20 PM in a room that will be announced on Courselink. Attendance at the poster session is mandatory for all students, so plan your extracurricular activities and jobs accordingly.
Students will be divided into two groups, presenters and evaluators. For the first 90 minutes, the presenters will present their poster in 5 minutes or less (with up to 2 minutes of questions afterwards) to their evaluators, and will be assessed using a provided rubric. After 90 minutes, the student presenter group and evaluator group will switch roles. Students serving as evaluators can form groups of 4 students and visit each poster together to minimize the number of presentations their peers need to give.
Section 3.1.5: Formal Lab – Poster (Peer Evaluation)
Each student will use a provided rubric to grade their peers’ poster presentations. Constructive feedback must be provided, which will be assembled and forwarded to the presenters anonymously. You will be evaluated on the quality of the feedback that you provide your peers.
Section 3.1.6: Group Project – Essay
During the first 5 weeks of the semester, students will work in groups of two or three students, randomly assigned by the course instructor. Each group will submit a collaborative essay, aimed at their peers in the style of a Scientific American article, describing a famous physics experiment or experiments. This essay will provide an overview of the relevant physics, particularly the experimental considerations, and describe the impact of that experiment on physical theories and understanding.
Suitable historical experiments include:
- invention of masers and lasers by Townes
- Michelson-Morley experiment testing the luminiferous aether
- Davisson-Germer experiment proving the de Broglie hypothesis
- Stern-Gerlach experiment and the discovery of spin angular momentum
- observation of quantized energy states in atoms by Franck and Hertz
Nuclear and Subatomic Physics
- Rutherford’s alpha-particle scattering experiment
- Chadwick’s discovery of the neutron OR discovery of nuclear fission by Fermi, Hahn, Strasser, Meitner, and Frisch OR discovery of artificial radioactivity by the Joliot-Curies (relevant to BMPH majors)
Biophysics and Soft Matter Physics
- Franklin’s X-ray crystallography experiments with DNA
- Pockels-Langmuir-Blodgett trough experiments
- Perrin’s study of colloidal suspensions
Electricity & Magnetism
- discovery of electromagnetic waves by Hertz
Condensed Matter Physics
- discovery of the transistor by Bardeen, Brattain, and Shockley
- experiments revealing the thermoelectric effect by Seebeck and Peltier
Students who wish to discuss a different project or experiment can do so if they receive permission from the instructor. Student topics must be unique to avoid overlap with other groups in the class. Students should avoid choosing essay topics that are closely related to previous summer research projects.
Essays will be submitted via Dropbox as PDF documents by midnight on Monday, February 5th (Group A students) or Monday, February 12th (Group B students). Do not leave your essay to the last minute: weeks 5 and 6 are typically very busy, whereas the workload in the first three weeks of the semester is relatively light.
Section 3.1.7: Group Project – Oral Presentation
Each group will present their chosen topic to their peers. The presentations will be no longer than 15 minutes, with 5 minutes for questions. Oral presentations will be held from 2:30 – 5:20 pm on Monday, February 5th (Group A students) and Monday, February 12th (Group B students). The location will be announced on Courselink.
All students are expected to attend the full 3 hours of the presentation day they sign up for. The presentations will be held during scheduled class time, so students must arrange their extracurricular activities and jobs accordingly.
Section 3.1.8: Group Project – Peer Evaluation
Each student will use a provided rubric to grade the oral presentations of their peers. Constructive feedback must be provided, which will be assembled and forwarded to the presenters anonymously. You will be evaluated on the quality of the feedback that you provide your peers.
Section 3.1.9: Lab Skills & Performance
Throughout the semester, the instructor and teaching assistant will be monitoring student attitudes and initiative in the laboratory. Students will be assessed on their willingness to try to understand experiments on their own (within reason – we do not want students wasting their time when they have no idea what to do next and we certainly do not want equipment to be damaged), their preparedness for labs throughout the semester, and their ability to adhere to established lab safety protocols (e.g. no food or drink of any type in the lab room!). Students are required to attend the lab during the assigned lab periods (2:30 – 5:20 pm on Mondays and Wednesdays), and attendance will be factored into this grade.
Section 3.2: Time Conflicts Between Courses
Sometimes students will have a time conflict between a midterm exam in another course and either a lecture or a lab in this course. The University has a very clear policy to cover this situation: the regularly-scheduled lecture or lab holds priority. In other words, it is the responsibility of the faculty member who has scheduled the midterm exam to make special arrangements with students who have conflicts.
Section 3.3: Course Grading Policies
Section 3.3.1: Missed Assessments
If you are unable to meet an in-course requirement due to medical, psychological, or compassionate reasons, please email the course instructor or TA. See the undergraduate calendar for information on Regulations and Procedures for Academic Consideration.
Section 3.3.2: Accommodation of Religious Obligations
If you are unable to meet an in-course requirement due to religious obligations, please email the course instructor within two weeks of the start of the semester to make alternate arrangements. See the undergraduate calendar for information on regulations and procedures for Academic Accommodation of Religious Obligations.
Section 3.3.3: Mark Adjustments
If you have questions about any grade, please inquire promptly after the material has been returned to you. Students are ultimately responsible for ensuring that the grades on all submitted material were entered properly in Courselink – check the entered grades frequently throughout the semester and report any discrepancies to your teaching assistant or course instructor.
Section 4: Aims and Course Objectives
Section 4.1: Calendar Description
This is a modular course for students in any physics-related major in which techniques of nuclear, solid state and molecular physics will be studied.
Section 4.2: Course Aims
This course allows students to perform some basic but important experiments that illustrate topics discussed in third and fourth year physics courses. The students will obtain experience using modern laboratory instruments and practice methods of data acquisition and analysis. The student’s scientific communication skills and ability to search the scientific literature will be developed.
Section 4.3: Learning Objectives
At the successful completion of this course, the student will have:
- become proficient with various experimental physics tools, including multimeters, oscilloscopes and multichannel analyzers.
- Learned to operate relatively independently in an experimental physics setting.
- mastered the analysis of experimental data, using accepted error analysis methodologies, to verify theoretical predictions.
- built upon their experience in PHYS*2180 to develop proper scientific lab notebook protocols.
- demonstrated intermediate proficiency with laboratory and radiation safety protocols, including proper handling of sealed gamma-ray emitting sources.
- Further developed the written and verbal skills introduced in PHYS*2180 to disseminate experimental results to a variety of audiences via scientific papers, posters, and oral presentations.
- identified and synthesized relevant scientific literature to present a coherent scientific argument at a level appropriate to their peers.
- demonstrated proficiency at incorporating theoretical knowledge developed in other physics courses and the scientific literature to draw appropriate inferences and conclusions from experimental results.
Section 4.4: Instructor’s Role and Responsibility to Students
The instructor’s role is to aid students in their performance of various experiments and provide guidance as students develop their mastery of the underlying physical concepts associated with these experiments.
Every student has the right to participate and contribute in the laboratory and other course activities. If a student feels that there is something preventing their full contribution, they must notify the course instructor or teaching assistants as soon as possible. We cannot fix problems that we are not aware of!
The instructor will ensure that the learning environment is free from harassment of any form. Offensive or inappropriate (homophobic, racist, sexist, etc.) comments are strictly prohibited. Offending students will be required to leave the lab or class, and a mark of zero will be given for any assessments arising from that course activity. More serious cases will also be forwarded to the University of Guelph Judicial Committee, where the maximum penalty is suspension or expulsion from the University of Guelph. For more details, students should consult the University of Guelph’s current Policy on Non-Academic Misconduct.
Section 4.5: Students’ Learning Responsibility
Students are expected to take advantage of the assigned laboratory hours, as these are the only hours where students are guaranteed access to the course instructor and teaching assistant. All students are expected to attend the assigned classes and the lab performance grade will be based on assessments of student performance during these time periods.
Students who do (or may) fall behind due to illness, work, or extra-curricular activities (including varsity sports, student leadership activities, etc.) are advised to keep the instructor informed such that extra resources or accommodation can be provided, if appropriate.
Students are expected to complete their lab notebooks, formal lab reports and term projects in a timely fashion. Students are provided with deadlines for course materials at the beginning of the semester and are expected to work towards those deadlines accordingly. Extensions will not be granted except in exceptional medical or compassionate circumstances. Students should not wait until the deadlines to complete their coursework, as other course deadlines will start to interfere with the posted deadlines in PHYS*3510.
Section 4.6: Relationship With Other Courses & Labs
Section 4.6.1: Prerequisite Courses
Students must have completed PHYS*2180.
Section 4.6.2: Restrictions
Section 4.6.3: Follow-on Courses
Experiments in PHYS*3510 complement lecture material in other third year courses, most notably PHYS*3000 and PHYS*4040. Experimental concepts introduced in PHYS*3510 will be built upon in PHYS*3170, PHYS*4120, PHYS*4130, PHYS*4150, PHYS*4070, and PHYS*4500. Lab notebook and scientific presentation (both verbal and written) skills developed in this course will be mastered in PHYS*4500 and PHYS*4001/4002.

Section 5.2: Experiment Scheduling
Students will be asked to split into two equal groups, Group A and Group B. Those in Group A will begin experiments in Week 2 and will have one week to complete the data collection for that experiment. Students in Group B will then have access to the equipment in Week 3, for one week. The two groups will alternate in this fashion throughout the semester with Group A doing experiments during the even weeks and Group B doing experiments during the odd weeks. All experiments should be completed by Week 11.
Students are required to complete the experiments during the assigned lab periods. Students requiring additional time to complete an experiment may sign out keys to MacNaughton 417 from the course instructor (see Section 6.3) in the rare occasions that an experiment cannot be completed in the allotted 6 hours of lab time.
Each student will be required to do 5 of the labs listed below:
- Electron Spin Resonance
- Zeeman Effect
- Millikan Oil Drop Experiment
- X-Ray Fluorescence: Moseley’s Law
- Gamma-Ray Spectroscopy Using a NaI(Tl) Detector
- High-Resolution Gamma-Ray Spectroscopy
- The Speed of Photons: Galileo’s Technique Modernized
Solid State Physics
- X-Ray Diffraction (ask for permission – currently under repair)
- The Hall Effect and Semiconductor Band Gap
Thermodynamics and Statistical Physics

Waves and Optics
- The Velocity of Sound: The Debye-Sears Experiment
- The Transmission Line
- Fourier Optics
- Physics of Ultrasound
Section 5.3: Signing Up for Experiments
Students can sign up for experiments using the Google Sheets link provided on Courselink. Please do not sign up for experiments outside of your assigned weeks unless all the groups for that week have already signed up for an experiment. Do not sign up for the same experiment as another group in the same week! Experiments are assigned on a first-come, first-served basis.
Section 5.4: Other Important Dates
Friday March 9th is the fortieth class day, the last day to drop one semester courses.
Section 6: Lab Safety
Section 6.1: Department of Physics Laboratory Safety Policy
The Department of Physics is committed to ensuring a safe working and learning environment for all students, staff and faculty. As a student in a laboratory course, you are responsible for taking all reasonable safety precautions and following the lab safety rules specific to the lab you are working in. In addition, students are responsible for reporting all safety issues to the graduate teaching assistant or course instructor as soon as possible. Students are not required to work in an environment that they deem to be unsafe. If you have any concerns whatsoever, please consult your teaching assistant or course instructors!
In this course, students may be exposed to the following potential hazards:
- \(\gamma\)-radiation and x-ray sources
- intense light, including laser light and strobe lights
- voltages and currents that can be harmful if proper precautions are not taken
- compressed gases
- cryogenic liquids: liquid nitrogen and liquid helium
All experiments have been designed such that students have minimal (but not zero!) risk if proper laboratory protocols are followed. At all times, students must be aware of the risks of their experiment and the positioning of their fellow students and behave accordingly.
Section 6.2: Food and Drink in the Laboratory
As with all laboratories on the University of Guelph campus, ALL food and drink is strictly prohibited in the laboratory. This applies to all faculty, staff, and students. In the PHYS*3510 laboratory, this rule is strictly enforced as a criterion for lab certification with the Radiation Safety Office at the University of Guelph. Students must not, under any circumstances, bring any food or drink into the laboratory. If students have water bottles or food in their backpacks, these must be left at the front of the room and not be accessed within the room at any time.
Section 6.3: After-Hours Access to the Laboratory
Students who need to work on their experiment outside normal course hours may sign out a key to MacNaughton 417 from the course instructor, on a case-by-case basis. Students must ensure that they are never in the laboratory alone, and must obey all safety rules. Should a course instructor, teaching assistant or lab supervisor come across students with food or drink in the laboratory, the offenders will be removed from the lab and receive a mark of 0 on that experiment.
Section 7: Academic Misconduct and Collaboration
Section 7.1: Collaboration
Collaboration and communication are essential for progress and advancement; much of modern society is built upon these skills. Students are encouraged to collaborate and discuss course concepts! However, all material submitted for grading must be each student's own work. Plagiarism is a form of academic misconduct, and will not be tolerated.
A good guideline when it comes to crossing the line from collaboration to academic misconduct (see next section) is that a student must never look at another student’s written work. For the vast majority of students, they will be incapable at arriving at their own form of a derivation or analysis after they have looked at another student’s work. For students seeking help from their peers, ask conceptual questions as opposed to, “How do you derive Equation 4?” For student helping their peers, never give the answer explicitly, but explain your reasoning.
Section 7.2: Academic Misconduct
The University of Guelph is committed to upholding the highest standards of academic integrity and it is the responsibility of all members of the University community – faculty, staff, and students – to be aware of what constitutes academic misconduct and to do as much as possible to prevent academic offences from occurring. University of Guelph students have the responsibility of abiding by the University's policy on academic misconduct regardless of their location of study; faculty, staff and students have the responsibility of supporting an environment that discourages misconduct. Students need to remain aware that instructors have access to and the right to use electronic and other means of detection.
Please note: Whether or not a student intended to commit academic misconduct is not relevant for a finding of guilt. Hurried or careless submission of assignments does not excuse students from responsibility for verifying the academic integrity of their work before submitting it. Students who are in any doubt as to whether an action on their part could be construed as an academic offence should consult with a faculty member or faculty advisor. The Academic Misconduct Policy is detailed in the Undergraduate Calendar.
Section 7.3 Turnitin
In this course, your instructor will be using Turnitin, integrated with the CourseLink Dropbox tool, to detect possible plagiarism, unauthorized collaboration or copying as part of the ongoing efforts to maintain academic integrity at the University of Guelph.
All submitted assignments will be included as source documents in the Turnitin.com reference database solely for the purpose of detecting plagiarism of such papers. Use of the Turnitin.com service is subject to the Usage Policy posted on the Turnitin.com site.
A major benefit of using Turnitin is that students will be able to educate and empower themselves in preventing academic misconduct. In this course, you may screen your own assignments through Turnitin as many times as you wish before the due date. You will be able to see and print reports that show you exactly where you have properly and improperly referenced the outside sources and materials in your assignment.
Section 8: Accessibility
Section 8.1: Accessibility
The University of Guelph is committed to creating a barrier-free environment. Providing services for students is a shared responsibility among students, faculty and administrators. This relationship is based on respect of individual rights, the dignity of the individual and the University community's shared commitment to an open and supportive learning environment. Students requiring service or accommodation, whether due to an identified, ongoing disability or a short-term disability should contact the Student Accessibility Services as soon as possible.
Section 8.2: Electronic Recording of Classes
The electronic recording of classes is expressly forbidden without the prior consent of the instructor. This prohibition extends to all components of courses, including, but not limited to, lectures, tutorials, and lab instruction, whether conducted by the instructor or teaching assistant, or other designated person. When recordings are permitted they are solely for the use of the authorized student and may not be reproduced, or transmitted to others, without the express written consent of the instructor.
Section 8.3: Posting Course Materials on Websites
Posting any course materials, including lecture notes or experiment outlines, is strictly prohibited. These materials are copyright of the course instructors, Department of Physics and University of Guelph.
Section 9: Course Evaluation
Section 9.1: Course Evaluation
The Department of Physics requires student assessment of all courses taught by the Department. These assessments provide essential feedback to faculty on their teaching by identifying both strengths and possible areas of improvement. In addition, annual student assessment of teaching provides part of the information used by the Department’s Tenure and Promotion Committee in evaluating the faculty member's contribution in the area of teaching.
The Department's teaching evaluation questionnaire invites student response both through numerically quantifiable data, and written student comments. In conformity with University of Guelph Faculty Policy, the Department’s Tenure and Promotions Committee only considers comments signed by students (choosing "I agree" in question 14). Your instructor will see all signed and unsigned comments after final grades are submitted. Written student comments may also be used in support of a nomination for internal and external teaching awards.
Note: No information will be passed on to the instructor until after the final grades have been submitted.
