Instructions (source cover)
1\. Do not turnover this page until you are told to do so.
2\. Write your ID Number and Seat Number on the space provided.
3\. Follow all the instructions carefully.
4\. Write your answer only on the separate answer sheet. There are 5 pages in the answer sheet.
5\. There are two experiments in this test. Make sure to answer BOTH papers to get full points.
6\. For the group experiment: ONLY the procedure of the experiment is done by group. The paper must be answered individually.
7\. Complete all the sections in English. There are Section I, II and III for the Group Experiment and Section I and II for the individual experiment.
8\. The marks awarded for each section or question is shown in brackets, [ ].
9\. There are 5 printed pages in this booklet, excluding this cover page.
10\. You have 120 minutes to complete this test.
Editorial navigation: the 120 minutes cover both experiments together. Vietnamese is a study translation; the original instruction to answer in English is preserved. No candidate ID or work is included.
INDIVIDUAL EXPERIMENT · Which Magnet is Stronger?
There are only a few things which are attracted to a magnet, iron and steel being the main ones. Very few other metals do, and no non-metals like plastic, wood, glass, and cloth are attracted. The main strength of a magnet is at the poles which lie at each end of a magnet, or each side of a circular magnet.
Objective: To develop a plan to find the strongest magnet.
Materials: Each student will need:
- two bar magnets
- plotting compass
- ruler
- several paper clips
- a ballhead pin
Procedure
From the given materials, devise ways on determining the strength of the magnet provided. You must draw and label your own procedure, create a data table, and gather necessary observations or results. Limit the number of methods into three only.
Section I: Data Tables

[6 marks]
Section II: Guide Questions
1\. Based on the three methods you devised, what variables did you look for when choosing the stronger magnet? [1.5 marks]
2\. How do you know which magnet is strongest for each method you devised? Explain. [1.5 marks]
3\. Which of the methods you devised is most reliable? Explain. [1 mark]
