Required Lab Manual, WebAssign and Canvas Webpage

Because you will record your experimental results in the manual, you must have an unused copy of the current manual to participate in the class:

Physics 118: General Physics Laboratory - Heat and Electricity, Winter, Spring & Summer 2017 by the Faculty of the Department of Physics, published by Fountainhead Press (ISBN 978-1-68036-494-1). It may be purchased at the University Bookstore for about $16.00.

Online homework (Pre-Labs and Post-Labs) are done on WebAssign Look here for information about getting on to WebAssign and what to do if you are having trouble with WebAssign access or need to contact someone to solve a WebAssign use problem.

Connect to WebAssign:

Attendance to the lab sections is recorded on the UW Canvas system, not WebAssign. Contact your instructor to obtain the web address of your Canvas lab course, or look for it on MyUW.

Course Structure and Grades

The lab course has two required parts: (1) a weekly two-hour lab session and (2) online homework with both Pre-Lab and Post-Lab components. This link describes the course structure in detail.

Physics 118 is a credit/no-credit (C/NC) course. To obtain credit a student must pass both the In-Class and the Homework parts of the lab course. To pass the In-Class part of the lab the student must attend all In-Class sessions (either as regularly scheduled or as make-up), that is, get 80/80 In-Class points. To pass the Homework part the student must earn at least 50%, or a minimum of 50/100 of the lab Homework points. Failure of either part of the lab will result in no credit for physics 118.

Due Dates and Make-up Work

Assignment Due date & time Make up policy
Online Pre-Lab Sunday night, 11:59 PM before lab session begins. Never.
In-class session Attendance required at scheduled time for section. Attend another session during week, or attend make-up week session.
Online Post-Lab Sunday night, 11:59 PM, following lab session. Automatic request from WebAssign for one 24 hr period within 7 days of due date. A 40% penalty is applied. After 7 day period, no make-up allowed.

Attendance is required to the regularly scheduled lab section. The TA will initial the lab papers at the end of the In-Class session and record satisfactory completion of the In-Class part. Students must have the TA's final initials in order to assure credit for attending the session.

Make-ups are allowed during another session in the same week, or one lab may be made-up during the make-up week without special permission(plus one more with special permission).

In some cases, missed work may be excused. This link explains the policies.
