[quote=\"Supitsme\"]Anybody can give all the options for q15

It's a graph right???

Quite hard to draw it here....

But I remember

Option 2 was number of plants.
Option 3 was about oxygen
Option.4 was about nutrients.

I thought nutrients should increase as fertilizers is nutrients? Option 4 states a decrease in fertiliser. I chose increase in bacteria. please explain. Thank you[/quote]Option 1 is nutrients, option 4 is bacteria.

After the point of G the water plants in the river start to die. So it's decrease of nutrients.

The only thing I'm unsure is why there was an increase in the graph after a period of time, and that happen to all graphs which bewilders me.

Is it correct?

What's the answer for q30 and the wheel chair question a?

Gravity pulls the wheelchair down so more electrical energy was needed to move the wheelchair up. (something like that)

My answer was:the wheelchair was moving up and against gravitational force so more electrical energy was needed to pull the wheelchair up. Not sure if. It is right :please:
Btw what is question 30 about

Hi everyone!


It's the officially the end of PSLE! (for some of you) Give yourself a pat on the back for 6 years of hard work! My opinion on Science is that if you are careful, the paper should be all right. I think booklet B was tougher than booklet A. Also, a few of the questions I did in the PSLE BOOK (2008-2012) came out!! :boogie: :rahrah:
For the condensation question, I put cold steel.

The force question I put option 1 (Blocking out sunlight)

Anyone knows the answer to the question on the curved metal pipe?

Also, I put: \"The person on the wheelchair is going against gravity, thus he needs to overcome the pull of gravity when going up while when he is going down, he is going with the direction of gravity pull\" for the wheelchair question @NerdyMath

In a nutshell, this paper was definitely harder than the qn I had seen in the previous years. Good luck for those taking HMT tomorrow! Add oil Add oil :rahrah: :rahrah: :rahrah:
