Q&A - P3 Science

[AgonyMum]

Hi ponyo,

The questions are from Longman assessment book, I think. I cannot recall all these ginger, onion thingy taught in Primary schools. I find all these quite dry and boring

ponyo:

Hi Agony Mum
am surprised these are tested at P3. Remember studying some of these when I was P4/5 decades ago... (how times have changed ).

Just to add on to Champion's reply, both egg white and yolk serve as food for the embryo during incubation. Think it's the albumen in the white that provides nutrients /water to the embryo. However, the white also serve as a protection for the yolk.

Also, regarding the bulb/ginger question, to be more precise a ginger is a rhizome although they (be it bulbs or tubers or rhizomes or stolon/runners) are all broadly categorised as underground stems. But not all underground stems are bulbs. Hope I have not confused you.

btw, just out of curiosity, did you get these questions from assessment books or exam papers?

Cheers
Ponyo

1) Is glass a man-made material or natural material?


Different books state differently. But I will go for man-made material. Glass is a man-made material made up of things that were obtained from the ground.

Again, I am not comfortable just to go and explain this to my DD as teacher may think differently. Hence decided to ask our experienced parents. Please share your views.

2) Metal - man-made material or natural material?

3) Tin - how to explain tin does not refer to coke tin but is a kind of metal?

Thank you in advance.

I have one more question.


State 2 differences between seal and XXX (can not exctly remember what is given here)?

My DD's answer:
1) Seal is a mammal while XXX is a fish
2) Seal has hair as the outer covering and XXX has scales outer covering.

Is this answer acceptable? The reason why I am asking this is because if seal is a mammal, of course its outer covering will be hair. So will the examiner see this as one difference or two differences?

Thank you

I know this question is discussed under Science assessment/guide books section few months ago. But any parent come across this kind of question in the school papers and what is the teacher's preffered answer?

[color=#4040BF]I would explain in term of whole pharses such as, if the question refer to glass material, then it is natural. But if it is refered as glass object ' like glass bottle or spectacles lenses, then it should be man-made.

[/quote]Thank you much. I understand this, but my DD did not catch the ball yet. I try to explain to her again.

For P3, you just need to remember glass, plastic, polylester and fiber are man-made. The above is taken from TLL notes…

This is a common exam question…

I feel this is right.
Glass is not found in nature directly. I can only be made thru a chemical process . So It should be considered a man-made material.
