My son's SA1 Science Paper had a simple question:

State one similarity between the platypus and the lion.

He answered : Both of them are mammals. The teacher marked him wrong. The answer should be : They are both warm-blooded.

Can anyone please help me understand why my son was marked wrong?

Many thanks Confused

I did a search on wikipedia to prove your son's answer.

So either Wikipedia is wrong or your son's teacher is wrong.




Anyone here that has better knowledge care to comment on why the answer is wrong?

You are expected to describe the characteristics of the two animals and not the groups they belong to.
Expected answers are:

Both have fur or hair. (describe the mammals)
Both animals take care of their young and feed them with milk.
Both animals are warm-blooded.
Both animals are vertebrates / have backbones.

Hi Jeffrey & Tang

Many thanks for both your answers. Big Grin Now I understand and it makes sense.

I was told that in order to excel in science, the child must remember key words or key concepts when answering questions. However, I feel that this method of stressing to the children that key words are very important and must be memorised is not a correct method of teaching. It's like forcing them to study "within the box" Children must be taught (explained) that in science, there are certain ways of answering questions, mainly, (as I was told by an ex-teacher) the answer must have scientific reasoning or as in the case of the question I posed, charateristic is what is expected and not grouping. It's no wonder that others think Singaporeans do not know how to think "outside the box"!

Hi all,
Just re-visiting this question, and after reading the explanations given by all, I still think the teacher is wrong. Question asked simply was "what is the similarity?" Nothing was asked about the group or characteristics of these two animals. So both these animals are similar because they belong to the same group = mammals. Absolutely nothing wrong with this answer. Perhaps you QueeSiang can claim that extra mark from your son's teacher.

i totally agree with QUEESIANG comment,
Science is not about a set of answers fix all solution ,
its about creative learning , giving all possible opinions that are back by facts & new finding ,
we should not penalize a student for giving an answer that is not from the answer sheet guide line, as the teacher for your child definitely do not have passion in teaching.

if you learn thru memorizing, you will definitely forget it,
but if you learn thru experience , you will definitely live to remember it

the Question
My son's SA1 Science Paper had a simple question:
State one similarity between the platypus and the lion.

there are over 100 similarity,
eg answers both animals eat , drink , sleep , hear & etc ,

the problem is the question itself

Sorry for a very late reply. I saw this post only now.
reading this question, there is a dissimilarity if you ans as mammals, as lion give birth to young alive whereas platypus lays eggs then suckles. hence your son's ans could be proved wrong. yet i totally agree that this cant be expected from a p3 grader until they are taught to analyse in such an angle and give the answer.

Yes, both are mammals BUT,
although most mammals give birth to young alive,
the platypus: Eggs
but it still suckles its young
the teacher is wrong

No point arguing if the teacher is right or wrong. teach your child the right way to answer such question and that is to list only the few characteristics they've been taught and told repeatedly in school.
they have hair
they are vertebrates
they are warm blooded
These questions will still come out in the next few years.

Hi all,
Regarding the question about the similarity between the lion and the platypus, the child has answered one of the characteristics. As given by Nicholas, the answer is perfectly correct. It was the teacher who gave this ambiguous question to students to be commented. Poor students!
