Evaporation and Condensation


Your loving mother put some hot Tiong Bahru Paos (buns) in a transparent plastic hood. After a few minutes , water droplets are observed to be formed on the inner surface of the hood. Is it right to say that hot water vapours from the paos (buns) condensed into water droplets when they touched the cooler interior surface.

Finally, I can find some logical explanation to show where does the water vapour of the paos come from.It may come from the dough used to make the pao skin(water is mixed with flour) and perhaps water used in mixing internal fillings.During the steaming of the paos at an earlier time,water had been absorbed.

Anyone can confirm if this year's PSLE Sci paper will be based on new or old syllabus?

The new sci syllabus omits topics like the Solar System and Simple Machines. So do students need to revise such topics for their PSLE? Anyone has any idea when will PSLE Sci incorporate the new syllabus? :?

PSLE Science 2009 is still using the old syllabus. The Solar system and Simple machines are included.Only P6 students are still using the old textbooks. Those in P5 and below are using the new textbooks(lower block/upper block)

It still the old syllabus. The PSLE 5-year series are out, make sure you get a copy.

So i suppose the new syllabus will take effect in 2010 PSLE?


Aren't P6 students next year be at a disadvantage, since they were not taught the complete new syllabus? Cos they were not aware of the changes made to the current lower block syllabus.

The syllabus for lower block is about the same as what they learnt in P3. The only difference I see is the way in which the topics are structured according to the themes. Syllabus wise, not much of a difference for P3. They started with the few books for lower block in P4.

Accordingly to this MTP session at Tao Nan on 07 Feb 2009, pls refer to http://www.taonan.moe.edu.sg/index.php?option=com_content&view=article&id=273:school-briefing-february-7-2009&catid=84:parents-downloads&Itemid=140 :

Q – Since this year’s P5 is the first batch of students taking the new syllabus for Science for PSLE next year, will they be doing past year papers as their PSLE preparation? Will it be relevant?

A – P5 2009 will be doing the PSLE booklet as P6 2010. They will also be doing past year questions from other schools. They will still be relevant as the question type and skills tested remain the same, though there is some content reduction.

Q – Any changes for exam topics and format as compared to previous years?

A – In 2010, PSLE will have 30 MCQ questions (unchanged) and 14 open-ended questions (changed from 16).

Hope this helps.
