[quote=\"janet88\"]hi lee yl,

your daughter's psle is OVER! now you can relax.

Hi Janet,
Just saw your post. One more paper to go tmrr. But DD2’s easily distracted the whole day. Told her she can go and sleep only after 10.30pm. 30 mins more and I will be liberated!!!

lee_yl,
Yr DD2 taking HCL? All the best. Hope she's got good focus & do well. [/quote]Yes, tmrr HCL will be her last paper.

All along, she has short attention span but I think she is taking PSLE seriously cos she can remember many questions, showed she tried her best to read the questions carefully. :xedfingers:

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
