Hi jesline,


sorry i dont have that info. But if you are interested someone had posted the results for 2007 and 2008 results.

hi atutor,


Thanks for your input.
My mistake for adding thermos to flask. It was not a vacuum(thermos) flask. it was a flask, diagram (cross section). The walls were hollow and filled with air.
The question was why it could retain heat better than the other container (flask) same material no air in between.

In any case whats with the 1 mark. you either give the 2 marks or nothing at all. Another thing that i have to clarify with her.

cheers

Hi Greg,


From what i gather from my son, its a good school. In sports the girls are more accomplished than the boys. Not sure why.
Generally cedar tends to take part and win more accolades in a more academic competition like math olympiads

More hands on and outdoor interaction. The principal calls it a more Holistics approach. was skeptical at 1st, but since they produce top grades in PSLE i've come to appreciate it.

Attended prize giving ceremony of last year for top students in class. 3 of 5 top winners for P6 were wearing Cedar girls outfit. thought that might interest you. :lol:

atutor2001:

There are other terms that must never be used. Another one is never use \"coldness\" - use loses heat. Oh no, my mind is blank. Will post more when I remembered. :oops:


Another one : Never use \"grow\" for non-living things such as metal when heated or shadow - use \"expands\" for metal and \"become\" for shadow.

Don't use \"soft\" if you need the material to bend - use \"flexible\"
Don't use \"flexible\" if you need the material to stretch - use \"elastic\"

Good list of words. I can see how the students might make the mistakes. Will be very useful for my son doing P3 now. Thanks

For PSLE Science, I remember my dds Science teachers’ telling them not to use “insulator”……

Always use good conductor of heat or poor conductor of heat

or

Object A is a better conductor of heat than object B

Or

Object B is poorer conductor of heat than object A

Thanks Dharma and Haley,

My nephew did his P5 CA2 recently. Some question relating to thermos flask and why they can keep heat longer. He answered it correctly quoting poor conductor of heat. Got one 1 mark out of 2. When my sister asked the teacher. the Teacher told her (very curtly) that the appropriate answer would be to talk about the insulating properties of the flask. My sister has a bone to pick with her since.

being the ignoramus as i was, told her to leave it, as i thought the teacher was right.

Now that i know that its officially discouraged in other schools...... :x. Lets just say the teacher is gonna need all the \"insulation\" she can get her hands on.

Appreciate your timely comments. You people rock!

Hi Niedino

Correct me if i am wrong but i think the reason for Q1 \"metal is a better conductor of heat than plastic, so heat is conducted away faster.\"
should be Metal is a poor insulator of heat so heat is lost to the surrounding faster

Hi,

We do not say that a material is an 'insulator of heat' that would be marked wrong. Nothing is an insulator of heat as everything can conduct heat to a certain degree. So we should say that metal is a better conductor of heat than plastic. If a material is a better conductor of heat, that means heat travels through that material very quickly.

[/quote]Hi Haleycopter and Bigdad

insulator of heat is indeed a valid term. Poor conductors of heat are good insulators of heat and vice versa. i believe it is still covered in the \"o\" level syllabus. \"Plastic\" heat properties question came out 2004 'O' level physics exam. Good Insulator/poor conductor both accepted.:D

I think you may have mistaken insulation to mean stop heat altogether.

definition i found on a website

Substances that do not conduct heat well are called insulators. The word insulator comes from the Latin word insula, which means island. Insulators have a low coefficient of conductivity; they do not conduct heat well. Nonmetals, such as wood, textiles, and plastic, are usually poor conductors. Gases are also poor conductors.

Wow, thread open from 2009. No takers? Anyways my son is a P3 student in this school. Just sending out my signal flare for any cedarian parent. Come rescue me!

Hi Niedino


Need confirmation on the following

A metal cup and a plastic cup both contain hot water of the same temperature. After 15 mins the water in which cup will have a higher temperature. Answer: water in the plastic cup Reason: metal is a better conductor of heat than plastic, so heat is conducted away faster.

What if the water is changed into cold water?
After 15 mins the water in which cup will have a lower temperature.
Answer: water in the plastic cup. Reason: metal is a better conductor of heat so it gain heat faster from the surrounding.

Thank you

Good update on this topic, must be one of those \"headache\" questions children come back from school with :stupid:

Herbie:

Hi i hv one qn.

Anthony asked Gloria, \"Where did you get this lovely shell from?\"
ans: Anthony asked Gloria where she had gotten this lovely shell from.
please advise. Tx

Hi herbie,

Your answer is correct. But I think 'this' needs to change to 'that'.

By the way, I am a bit confused over the answers here, I realized that
you asked about No Sooner, the answers given here is different from the one TAS gave when you asked.

I checked online and it seems the answer is No Sooner is used with than. Anyone wants to verify this? Anyone who had this question done in an exam and the teacher gave the confirmed answer?

So smurfette would be right to use \"than\".

Came across the question recently in another forum. The answer given by the person who posted it was

No sooner after the boy took some money from the drawer, his mother walked in.

:?


Checked with a Prof Michael Swan website : Some examples given were

“No sooner had I put the phone down than it rang again”.

“No sooner had I finished the meal than I started feeling hungry again”.


by the way the Swan guy wrote some books on English language teaching and English Grammar published by Oxford University Press.
