results if they follow your description.
Formal Technical Report
Results and Discussion
• Present the significant experiment results
required in the Lab Manual in words and graphs.

Oral Presentation
– Each group is required to deliver one oral presentation
based on the lab they have performed.
– The content of the presentation should include
introduction of the lab, theories and/or principles,
objectives of the lab, experimental procedures, data
collection, data processing, results and discussion,
conclusion and recommendation.
– The duration of the presentation is 13 -15 minutes.
– All the students in the same group will work
collaboratively, and will be evaluated as a group.
– All students must attend the group presentations and
participate the grading. Irresponsible grading will lead to
reduce of the overall marks.
