What did ya'll put for the magnet question in pp2 and pp1 the question where there were 3 containers ,one with a plant ,one with carbon dioxide and the last one air ?

the one with plant is the least and the one with carbon dioxide is the most.

Decomposer question:


Apart from scavengers i put put in a warm place as it encouages the growth of decomposers on the leaf.

The elphant question:

A the environment is hot so more heat must be lost to keep itself cool .


B the environment is quite cool due to the trees thus if it lose alot of heat its body temperture will be lower than normal causing it to die.


A few in my school also found it easy. Yeah the question like the windscreen were asked by my teacher efore p5 for me and my few friends qho pestered him untill he gave us remedial after every friday

just want to share my ds answer to the decomposition question - add WORMS!!

Hi, for the question about how he should obtain water, I put that he should tie up some leaves in a plastic bag with the string. "coz the concept behind my answer is the same as the concept behind part (a). I believe that both answers should be related and most of the people I know put the answer above.

There is a similar concept as this in the PSLE specimen paper in the Five Year Series, question 39, so those students who did the Five Year series faithfully should be able to explain the concept right.

So happy for all PSLE pupils. HMT not critical for most. Kids can hit their favourite games now.

For the elephant question, I put :

The big ears help to trap air which is a poor conductor of heat.Thus,keeping the elephant cool. Wonder if it is correct!!! :?: :!:
