Kirkup, L Experimental Methods for Science and Engineering Students (2nd Edition) (Wiley) is recommended for the practical work.

Reference books include:

• Giancoli, D. C. Physics for Scientists and Engineers with Modern Physics, Pearson New International Edition, 4th edition (Pearson Prentice Hall).
• Halliday, D, Resnick, R and Walker, J Fundamentals of Physics (11th Australian & New Zealand Edition)
• Tipler, P Physics for Scientists and Engineers (6th Edition)
• Ohanian, Physics: readable and has “interludes” or “essays” reflecting interests often expressed by students
• Marion and Hornyak, Physics for Science and Engineering: is more mathematical than required for our courses
• Serway, Physics for Scientists and Engineers with Modern Physics

MyUni: Teaching materials and course documentation will be posted on the MyUni website ().

This course will be delivered by the following means:

• 3 lectures of 1 hour per week
• 1 workshop of 1 hour per week
• 1 practical of 3 hours per fortnight

A student enrolled in a 3 unit course, such as this, should expect to spend, on average 12 hours per week on the studies required. This includes both the formal contact time required to the course (e.g., lectures and practicals), as well as non-contact time (e.g., reading and revision).

The course content will include the following:

Coursework Content

To obtain a grade of Pass or better in this course, a student must achieve a result of at least 30% in each practical and an overall result of 40% for the practical component and attend the final examination.

The coursework result comprises a contribution from your preparation for tutorials with the remainder from the in-semester tests and your written examination. The MyUNI quiz and the experimental work contribute to the result for practical work.

Workshop preparation and participation
Workshops are held weekly, starting in the second week. The grade for the workshop is based on the student’s preparation and participation during the workshop.

Practical work
There are five practical sessions which are all compulsory. For each practical, the student must obtain a Satisfactory result in the preparatory work, attend the practical session and submit the logbook for assessment. During the practical sessions, students work in groups of 2 or 3. The students in each group will select one of their completed experiments and cooperate to prepare a scientific poster which is presented in the final practical session. This poster will count for 25% of the practical assessment component.

In – Semester Tests
Up to 4 tests will occur throughout the semester.

Examination
The final examination will be based primarily on lecture/workshop material.

Submission of Assigned Work
Coversheets must be completed and attached to all submitted work. Coversheets can be obtained from the School Office (room G33 Physics) or from MyUNI. Work should be submitted via the assignment drop box at the School Office.

Extensions for Assessment Tasks
Extensions of deadlines for assessment tasks may be allowed for reasonable causes. Such situations would include compassionate and medical grounds of the severity that would justify the awarding of a supplementary examination. Evidence for the grounds must be provided when an extension is requested. Students are required to apply for an extension to the Course Coordinator before the assessment task is due. Extensions will not be provided on the grounds of poor prioritising of time. The assessment extension application form can be obtained from:  

Late submission of assessments
If an extension is not applied for, or not granted then a penalty for late submission will apply.  A penalty of 10% of the value of the assignment for each calendar day that the assignment is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days late or more without an approved extension can only receive a maximum of 50% of the marks available for that assignment.
