Laboratory Practice | Cert 4 |
2012
This subject does not provide a final mark to your course. It is linked to some of the units of competence that comprise
the certificate 4 qualification. These are listed as part of your enrolment / timetable package.
ASSESSMENT DETAILS
LABORATORY WORK HEALTH AND SAFETY (WHS)
Laboratory WHS is a compulsory unit incorporated within Laboratory Practice focusing on
WHS issues within the context of a science laboratory.
Event 1 – Major Assignment
Consists of a take home assignment covering topics relevant to safety in the laboratory. This
will be due for submission on 20 June 2012.
Event 2 – Laboratory WHS Quiz
Closed book assessment of laboratory WHS issues covered throughout semester 1.
LABORATORY PRACTICE
Event 1 – Exams
There will be TWO (2) practical exams and TWO (2) theory exams throughout the year,
assessing important aspects of this subject. These are scheduled in the 2012 program below.
Event 2 – Task Completion
Students are encouraged to undertake and complete ALL programmed laboratory tasks.
Your progress during each entire laboratory task will be closely monitored and recorded as
competent, upon satisfactory completion of all task aspects, including:
written record of prework, observations, results, calculations and task questions as they are
applicable to the task. A 5 min Risk Assessment must also be completed prior to
undertaking every task.
Event 3 – Full Laboratory Reports
A full report structure is required for completion and submission during FOUR (4)
compulsory laboratory tasks, as indicated on the practical timetable. See handout: Logbook /
Full Report Structure for further details.
1
Assessment will be ongoing throughout the entire year. Formal assessment events are described above. Further
observations of your performance in the laboratory, or supporting information will comprise aspects of your
informal assessment. These will also be recorded as part of your teacher’s markbook.
Informal assessment details may include, but not be limited to:





Preparedness for the task (you will receive a practical timetable).
Ability to follow procedures within a laboratory context with efficiency and competence.
Safety awareness in the laboratory.
General tidiness of your work area, during and at the end of the class.
Completion and / or submission of supplementary worksheets and assignments as they are issued.
