Yea. Overall paper need some thinking processing. Adaptation qn was challenging. MCQ was quite ok. There was one mcq about pollination. Something about what Z is being pollinated by...anyone have any idea?

I think I remembered that question now. My answer is pollinated by insects , two flowers

Yes. My DD also put the same answer. She say she don’t know what the qn wanted. Almost entire class people all have choices 1,2,3,4 as the answer. Confused.

Confused.[/quote]My reasoning is that the flower has strong smell thus attract insects. Some flowers adapt themselves to avoid self pollination by having pistil and stamen maturing at different time, which is so for this question, therefore is pollinated by two flowers . Not sure if I’m correct

Another question- how an insect that secretes sugary substance but cannot move much will benefit the ants? How will the ants benefit the insect.

[MdmLily]

The answer- the ants eat the sugary secretion while they protect the insect from predators like lady beetle as the insect cannot move further to escape.

What is the answer for the question on the magnet 'ding' and 'dong'?

According to my DS, there are 3 parts to this question.
a) When the circuit is closed, the coiled rod will be magnetised and attract the iron rod which will move and hit the bell, making Ding sound.
b) 2 ways to make Ding sound louder: (1) increase the number of coils (2) increase the number of cells.
3) Dong sound is made when the iron rod moves away from the bell and hit the plate which is on an opposite side. How to make Dong sound louder without changing iron rod or plate: The answer has to do with the spring attached to the iron rod. DS's answer is to use a shorter spring. Not sure if correct.

I’m not sure if part (c) is to use longer or shorter spring or whether to mover the plate further or nearer. Anyone knows

There was one question that my girl and her friend got different answers. The MCQ question was about three solids X, Y, Z.

Two statements were given:
A. The material making solids X and Y is the same
B. The materials making Y and Z were different

Which of the statement(s) could be concluded from the above experiment?

1). Both A and B
2). B only
3). A only
4). Neither A nor B

B, as Y and Z is definitely different in density given both are solid.
X and Y can be same material or different material, no way to tell with this experiment hence statement is in correct

There is a question in Paper 2 on Bird B leaving its eggs (which look similar) in nest of Bird A. Similar situation to a past PSLE question but the questions are different.

Hi parents! My daughter said that this time the science paper was slightly tough, and she rushed through the questions. There was one qn in the MCQ about the fertiliser in the pond. My daughter put first the amount of light is lesser, then the oxygen level decreases then the plants n fish decrease. But my daughter says that her friends all put an answer diff from her. For those who want to know what the qn is, the qn is about a farmer using fertiliser that would allow the floating plants to grow faster. Then there are a few options like the amount of light, fish decrease, submerged plants decrease, oxygen level decrease, and amount of light decrease. Then they asked for the sequence in which these would happen. Anyone, help? My DD says she already lost 4-6 marks.

I haven't seen the question yet but base on the above,

amt of light decrease->submerged plants->decrease->oxygen level decrease-> fish decrease

congrats leeyl for having another psle done

Lee_yl....envious of you ah. No more PSLE liao. :rahrah:
