PC131 Mechanics Lab

Evaluation Methods

• Marking Scheme (from the lab manual)
• Online quizzes
  Several weeks will have post-lab quizzes on MyLearningSpace. Look over the recap section of the lab or exercise before doing the quiz. If you don't get 100% on the quiz, reread the material to correct your mistakes and retake the quiz.
  The purpose of the quizzes is to help you retain the material and to prepare you for the lab test at the end of the term.
• Lab Reports
  • Lab checklist
  • Lab checklist explanations [ May 15, 2014 ]
  • Sample lab report [ January 26, 2011 ]
  • Sample lab (to go with sample report) [ May 21, 2010 ]
  • Another sample lab report [ November 9, 2010 ]

	Processing Uncertainties Writing a Lab Report
Oct. 5	Exercise Background: Processing Uncertainties Lab Exercise: Processing Uncertainties Can be done independently. You can start it ahead of time, and get as much done as possible, and then bring what you have to you lab period. The more you have done already, the less time you'll need to spend in the lab. You'll need to have Uncertain Results available, in print or electronically Make an appointment with the Writing Centre The window for appointments is Oct. 8 to Oct. 27 if your lab is Tuesday; the window for appointments is Oct. 9 to Oct. 28 if your lab is Wednesday. Remember you'll have to write up your lab report to take it with you to the Writing Centre. They can only advise you on what you have.
