Q&A - P3 Science

[nsmom]

Hi


My child in p4 seems to know the science well but has not scored well in SA1 (same last year science year also). He has done particularly bad in Section A (MCQ type). ANy help/advice/suggestions.. :?

thx in advance

My girl in P3 scored 95.5 in SA1 esp all correct in MCQ. I thk it because I had print out more than 20 past school exam papers for her to practice & she had done 3 to 4 assessment books to improve herself. No matter how bad, I still think that practice made perfect.

feels better to know other parents are facing the same problem .

Honestly, if we parents are here discussing about all these science questions meant for 9 to 10 yr olds, can we imagine what is going through the minds of our kids? what is MOE trying to proof by raising the level of science (and math) to such a level that is almost killing the kid's interest?

I think what is being taught is fair, but the way the questions are asked, it's beyond the cognitive level of a 9/10 year old.

if the only way of mastering the subject is by doing 30 to 40 past test papers and assessment books, MOE has to realise that the original intention of getting our kids to think critically has failed.

any idea how we can have a dialogue with MOE? going through the schools is useless. :?:

pardon my mini outburst here.

Hi

I can't think of any heading to describe the cahracteristics of the materials.
Option 3 and 4 are out.

Between 1 and 2, I'll go for (1).At this juncture, I can't think of any science concepts to back up my answer.

Option (3) is a logical choice.A metal gate has to be strong, able to withstand the environmental conditions, and should be able to conduct heat so that it would be comfortable for us to touch.

I'm not sure if I'm right, but this is my conclusion:

Answer: Option 1
Reason:
Items in group A are all made of ONE MATERIAL ONLY (stated specifically for each item):
cotton towel - cotton
plastic box - plastic
paper bag - paper
Metal spoon is made of 1 material only (as stated specifically, METAL spoon).

Items in group B are made of 2 or more materials:
bicycle - metal, rubber
watch - metal, plastic, sometimes glass
umbrella - metal, fabric (nylon)
Television is made of more than 1 material (metal parts, plastic, glass)

Hope my answer is logical

I beg to differ (but I may be wrong!).

Option 1 is my choice. Though option 3 is a real strong fight.

My reason:
Gates (assuming they are out in the sun/rain & not the type in HDB flats that hardly see 'sunlight') should not be able to conduct heat well.

Imagine this:
Hot day, sun beating down on the gate. The gate is a good conductor of heat, therefore will absorb heat energy fast. When you come home & decide to open the gate, it is HOT & you can't open it without 'burning' your hands.

The questions asks for SUITABLE PROPERTIES. Therefore, we should choose properties that are most desirable.

However, in real life, our gates are made of metal which is a good conductor of heat. But is that a desirable property? Do we love it when our gates are hot to touch & opening it is like 'torture' (you know it's hot but you just have to touch it!).

A poor conductor of heat will not be so hot & will not heat up so quickly also
