5. Sally wanted to find out which part of a magnet is stronger. She labeled her bar magnet into four different points, A, B, C and D, as in the diagram shown below.

Sally then placed the bar magnet onto a pile of metal paper clips. When she lifted the magnet, she observed that there was different number of paper clips attracted to each of the four points.

Which of the following sets of data would most likely be the result of Sally’s experiment?

JUSTIFICATION OF DISTRACTORS

QUESTION 3

Option Justification

1 Correct answer.

2

Pupils may select this option as both the absorption of water and minerals and the holding and supporting of the

plant are functions of roots of plants that are planted in soil.

However, the plant in this question is water hyacinth, which do not grow in soil but floats on water. Hence, its roots

do not help to hold and support the plant firmly.

Pupils who select this option shows that they have the knowledge and understanding of the functions of roots of

plants grown in soil, but they are not able to apply the concept these understanding to a new situation.

3

Pupils may select this option as they think that water hyacinth, being partially submerged in water, grows/lives in the

same manner as fishes. Hence, they may decide that, like fishes, plants that floats on water also absorbs the

dissolved oxygen present in the water.

4

Pupils may arrive at this option by elimination method.

Firstly, pupils may think that since water hyacinth is already partially submerged in water, it does not need to take in

any more water from its roots. Hence, statement A would be eliminated, and they would then arrive at Option 4.


QUESTION 5

Option Justification

1 Correct answer.

2

Pupils may select this option if they are unaware that there is a difference in strength of attraction at different points

of a magnet. Hence, they may think that the number of paper clips attracted will be random and not follow any

particular pattern. Only this option provides a random number of paper clips attracted at the 4 points.

3

Pupils may select this option as they think that the strength of attraction of a bar magnet is the same at any point of

the magnet. They may think that since the bar magnet was lowered horizontally onto the pile of metal paper clips, the

number of paper clips should be the same at every point.

These pupils have not shown understanding that the two poles of a magnet display the strongest force of attraction.

4

Pupils may select this option if their knowledge of this concept is unclear. They most likely have knowledge that the

strength of attraction is strongest at certain points of the magnet, but are unable to identify that it is the 2 poles.

Also, pupils may select this option if they do not have knowledge of where the poles of the bar magnet is at, and

hence are unable to select the right option.
