# Activity Name Hours per Week Sessions per Week Weeks per Semester
1 Lecture 2.00 2 13
2 Tutorial 2.00 2 13
3 Independent Study 2.00 1 13
4 Laboratory 3.00 1 2
5 Presentation 4.00 1 1
T&L Activities: Tutorial: After each lecture, there will be 2-hour tutorial on Thursday. Students will solve various problems relevant to the topics of the lecture.

Independent Study: Students are expected to spend about 3-4 hours of ‘self directed learning’ outside the specified contact periods.

Laboratory: Groups will be allocated in week 4. Each group will conduct 2 experiments. The report should be submitted after two weeks. There will be oral presentation for one of the experiments.

Presentation: Each group will present the outcomes of their research and experimental work. It is expected that each group conduct a critical thinking and analyse the data acquired from the experiments and discuss the errors.

Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.
