Q&A - P3 Science

[HAPPYH]

nms1:

My daughter's teacher recommended that they buy PSLE Ultimate Science guide. It wasn't originally on the book list but she said it is one of the best books available. They can use it from P3-P6. It is thematic and has example questions with hints on how to tackle them. My daughter actually enjoys reading it.

Oh, that's great. I have lower block ultimate science. I like the info too but my DD dont flip the guide as the fonts are very small. I am not sure about PSLE version. Is the font size bigger? I also have PSLE Revision Guide (MPAH) and PSLE guide from Fairfield. We rarely touch them now. Of course, I refer to those if we come across any discrepencies in the answers provided.

Pls refer past papers' answers.
my son just put A.i remember the answers like metal A.
i think plant A should be ok.cos usually they will ask why.so need to answer the reason.

Hi vinegar,


I think B should be the answer.

Recently just attended the workshop organised by the school and the teacher said that answer must be detail and specific.

How does the bread mould get its food?


Thank you

[mother777]

Bread mould is a fungi. So it will get its food by decomposing the bread and absorbing the nutrients.

Dear fellow KSPers,

This question (13b) came from my P3 gal's 1st Science test paper.

I find that the teacher's answer can be made clearer by further highlighting that the goldfish mass will increase faster as more food is given. Or an alternative answer could be: \"The more food given to the goldfish, the faster it will grow.\" or somewhere along this line.

In my opinion, the usage of the word \"increase\" doesn't seem quite appropriate in this case as it usually applies to a comparison of the same subject before and after. In this question, each goldfish is given the same amount of food everyday so there isn't any increase per se.

I would greatly appreciate your views pls. TIA!

for p3, the teacher’s answer should be ok. The qn is what is the relationship between amount of food and the weight.if the food increase the mass incrase. no need to go deeper.They tested that the kids can compare and make a conclusion.just my opinion from my son’s experience.

Hi,

This story is an interesting illustration of the perception of the concept “measurand”.

One perception is “By increasing the amount of food, will the mass of a fish increase?”

The other perception is “By increasing the amount of food, will the mass of a fish increase faster?”

In this case, probably, only “Andy” is unambiguously clear in his mind what he is measuring for or what the “measurand” is.

Therefore, if this question is to test a student ability to compare and infer than both answers should be acceptable.
