    Laboratory Log Book - experiment 1
    Type: Field Report
    Learning Objectives Assessed: 2, 4, 5, 6, 7, 8, 10, 11
    Due Date: Mid-Semester
    Weight: 7.5%
    Task Description: Students are required to keep a bound laboratory log book (e.g. spiral bound) in which all pre-work, notes and data readings taken during the experiment must be recorded. Loose pages are not to be used, except for graph paper which must be glued or taped in. Remember, everything goes into your log book. In your laboratory work book you should record
    1. Date of expt., group members listed, calibration checks complete
    2. Full details of the experimental equipment (Model No., Serial No., etc.)
    3. Complete description of the actual procedure used
    4. All raw data from the experiment
    5. Clear description of methods and techniques used to process data
    6. All processed data from experiment
    7. Clear description of theoretical analysis
    8. Discussion of results
    9. Analysis of experimental uncertainties
    10. Conclusions drawn from experiment
    This submission is to assess your log-book entry for experiment 1 and to provide feedback.
     
    Students may perform the experiment in groups of up to three and submit a single log book for assessment. The same criteria will be used in assessing log books from individuals and groups. For students working in groups, Peer Assessment will be used to moderate the marks of individual students based on their individual contributions to the assessment task.
     
    Submit a scanned copy of your Log Book online using the MECH3250 Blackboard site: Go to Assessment>Log Book for Experiment 1.
     
    Only one person in the group is required to submit the Log Book pages electronically. Make sure you are confident that this group member will submit on time. It is the final responsibility of all group members to ensure that the entry is submitted on time.
     
    Ensure that your submission has an assessment submission cover sheet and ensure that all group members sign the cover sheet. If it is not signed, the submission may not be marked.
