Lab Structure:

·         All PY 209 labs are completed by each student in WebAssign.

You MUST use the NC State Specific webpage for webassign login :

The labs are mostly ‘stand-alone.’ Students should be able read through and complete the labs with only the information given in WebAssign. Addition assistance will be given via Piazza (see below).

·         Students will collect/analyze data for each lab from online videos

o   This will include the use of software mentioned below

·         For each lab, there will be a short introduction video given by a Teaching Assistant (TA) that is meant to re-familiarize each student with the material for the lab as well as point out common mistakes, areas where students may have difficulty, and errors in WebAssign.

General Schedule:

·         Labs will be become available at 8:00 AM on the day the lab is officially scheduled in MyPack. Example; a Monday 3:00 PM lab and a Monday 12:50 PM lab will both become available at 8:00 AM Monday. Labs are due at 8:00 AM 7 days later.  Example; Monday labs are due 8:00 AM the following Monday.

·         Refer to the Lab Schedule link at the top of this page for the complete schedule.


·         Students will be able ask lab content questions in Piazza.

·         Piazza is an online forum where questions can be answered by lab TAs, course instructors, as well as other students.

·         Questions can be submitted publicly or privately. The intent of public questions is to encourage students to work together as well as to avoid the same questions being asked and answered multiple times. Please take a few minutes to read through previously submitted questions to see if yours has already been asked.

·         Questions may be submitted at any time, but your lab TA will be “on duty” Tuesdays and Thursdays 10:00 am – 12:00 pm and 4:00 pm – 6:00 pm.  During this time, your TA will respond very quickly to questions.

·         Director of Undergraduate Physics Laboratory: Robert Egler egler@ncsu.edu.

A WebAssign account is REQUIRED for every student in Physics lab.  Go to www.webassign.net/ncsu . The WebAssign license for lab assignments should be purchased from WebAssign at https://www.webassign.net/ncsu.  All lab instructions are imbedded in the lab assignments, so a separate lab manual is not required.

Adding a lab section after the 'Last day to add a course without permission of instructor' is NOT allowed.  Adding or switching a lab section for any reason after the University's Drop/Add Deadline it must be approved by the Assistant Department Head: Keith Warren, keith_warren@ncsu.edu.

Missing an assignment:  All assignments will count, i.e. none are automatically dropped. 

An extension will be given only when a student has a documented excuse that complies with the university policy described here: http://policies.ncsu.edu/regulation/reg-02-20-03, such as a documented illness or a family emergency. 


Expectations of All Lab Students

Plagiarism and Working Together:  You should complete all WebAssign free response questions on your own. Data collected from previous semesters (even if it was collected by YOU) or data that is collected by your group members while you were not present, or an answer with wording essentially identical to someone else in your lab group is not acceptable.  All suspected plagiarism will be evaluated and action will be taken to punish the violators. Supporting Fellow

Students in Distress: As members of the NC State Wolfpack community, we each share a personal responsibility to express concern for one another and to ensure that this classroom and the campus as a whole remains a safe environment for learning.  Occasionally, you may come across a fellow classmate whose personal behavior concerns or worries you. When this is the case, we encourage you to report this behavior to the NC State Students of Concern website: studentsofconcern.ncsu.edu/.  Although you can report anonymously, it is preferred that you share your contact information so they can follow-up with you personally.


Accommodations for students with disabilities:  Reasonable accommodations will be made for students with verifiable disabilities, registered with NC State Disability Services for Students, room 1900 Student Health Center.  The University policy on Working with Students with Disabilities is available on-line at:



WebAssign will automatically grade your assignment after the completion deadline has passed with the exception of short response questions. Your TA will grade the short response as well as check WebAssign’s ‘automatic grading’ a few days after the completion deadline.


It is YOUR responsibility to email your TA if you have any questions or concerns about your grade and or assignment deadlines.  However, please submit all lab content questions through Piazza.


ALL LAB GRADES ARE CONSIDERED FINAL at 11:59 PM on the last day that classes meet.  ALL discrepancies in grades should be brought to your Lab TA’s attention BEFORE that time.

Grades are calculated based on the un-weighted average of the lab and attendance scores.


Each lab is equally weighted.

Final lab scores will be rounded to the nearest whole number, such that fractions equal to or greater than 0.5 will be rounded up to the next whole number, and fractions less than 0.5 will be rounded down to the next whole number.  For example, 79.45 rounds to 79.5 which rounds to 80, which is a B-, and 79.44 rounds to 79.4 which rounds to 79, which is a C+.  The grading scale is as follows:

      A+ = 97 and up                       A = 93 to 96                            A- = 90 to 92
      B+ = 87 to 89                           B = 83 to 86                            B- = 80 to 82
      C+ = 77 to 79                           C = 73 to 76                            C- = 70 to 72
      D+ = 67 to 69                           D = 63 to 66                            D- = 60 to 62
      F = < 60

While PY 206 typically accompanies PY 205, PY 206 is a separate one credit course, and the lab grade in PY 206 does not affect the course grade in PY 205.
