Hi Tianzhu,

Thanks for the links.
They mostly indicate the platypus live on the banks, technically, not in water. So i think our answer of 1 should be correct.

Hi teh_oh


I think you can take it that they can live in water.

Here’s another link.

Hi, can anyone here advise me?


My son’s recent CA’s question:

Dave set up the experiment as shown below and left them untouched for one week.

It show 4 different experiment setups. I will describe as below.

SetupA: 1 grasshopper in a tank with leaves and cover with a lid with holes.
SetupB: 1 grasshopper in a tank with leaves and cover with enclosed lid (without holes).
SetupC: 1 grasshopper in a tank and cover with a lid with holes.
SetupD: 1 grasshopper in a tank and cover with enclosed lid (without holes)

One of the question was asked:

What does Dave’s experiment shows that living things need ________ to survive.

They are supposed to put a tick on the correct boxes for the above question.

Air
food
water
space

My son : indicate 2 ticks on the above question : He tick for AIR and FOOD.

But the teacher answer it as : Air, Food and Water.

My son told me this question is so unfair. cos’ the question asked "From Dave’s experiment. And in the experiment, there isn’t any WATER??? If the question asked in a more general way like "what does living things need _____ to survive, it it more straight forward. But it indicate as "Dave’s experiment", isn’t I suppose to based on the experiment?

What do you think? I felt my boy is correct too…

Hi,

Did the question state what happen to all the grasshoppers after a week?

Hi Tianzhu,
Thanks for your replies.
While some website state that they live in water, some said that they actually live near the river banks.
http://en.wikipedia.org/wiki/Platypus
When not in the water, the platypus retires to a short, straight resting burrow of oval cross-section, nearly always in the riverbank not far above water level, and often hidden under a protective tangle of roots.

Because unlike whales and dolphins which are mammals designed to breathe underwater, we felt that platypus are consider 'land' animals'; just our opinions. Ultimately, schools should not set such questions; they could have state 'They can swim' instead of 'Live in Water' for the last item in the table.

thanks again.

My son told me this question is so unfair. cos' the question asked \"From Dave's experiment. And in the experiment, there isn't any WATER!!!!? If the question asked in a more general way like \"what does living things need _____ to survive, it it more straight forward. But it indicate as \"Dave's experiment\", isn't I suppose to based on the experiment?

What do you think? I felt my boy is correct too...

I suppose the teacher's argument would be that the student should infer that \"water\" comes from the leaves. Then again, if this is so, the question should indicate that the leaves are juicy and succulent and provides all the necessary nutrients and moisture needed to keep the grasshopper's skin smooth and soft so that it feels that life is still worth living.

Hi 2bbtang,
Is the above the entire question? Sometime the questions may have been broken into parts and the student may infer from the different questions/parts leading this this one question.

However, having said that, some of the school question can be rather \"unfair\" but I understand from this forum that in PSLE there will be more stringent quality assurance process in setting questions so such ambiguous question I guess would be filtered out.

There are 3 questions under this.

Q1: (a) Which setup(s) will the grasshopper survive after 1 week?
Q2: (b) Explain your answer in (a)
Q3: (c) \"Third question is the one stated above\"

Anyway, I have checked with the teacher, the answer is the \"water\" is from the leaves. So there is water in the setup.

Sigh. Think, no point to argue. But my son feels is still unfair.

Hope, there will not be any ambiguous question like this in future.
Thanks to all.
