Lab Policy

Lab manuals will be posted on Canvas.

Lab reports are due on Canvas at 6:00 pm Champaign Time on the due date.

All the lab reports should be submitted to Canvas, in .pdf format.

Late lab reports will not be accepted, unless under exceptional circumstances approved by the instructor.

Background and Prelab of a lab manual contains relevant theory and background information of the experiment, which must be done before entering a new lab session.
