Tutor Niedino: Pri Science Questions and Concepts
-
How do you answer this question on Heat and Temperature the Singapore PSLE way?
Scenario : John nd Mary walked into an air-conditioned shopping centre during the daytime. They made the following comments:
Mary : Brr … it’s freezing cold in here.
John : Are you kidding? It’s so hot!
Q1. One of the teenagers above had just spent an hour packing frozen meat in the coldroom of a meat factory next to the shopping centre. Who is it?
Ans: John (easy enough)
Q2. Explain your answer.
The answer given in the assessment book is : "Since John packed frozen meat in a coldroom, he would feel very cold. When he next walked into the shopping centre, he could feel the effect of the increase in temperature more intensely. This made him feel hotter than it actually was."
But my daughter said her science teacher said science questions must be answered the science way : meaning the words ‘heat gain’ and ‘heat loss’ must be used.
How would you answer this question to the satisfaction of the graders? Pls help. -
Heat travels from a region of higher temperature to a region of lower temperature.Since John was in the cold room (lower temperature) before going to the shopping mall(higher temperature), he would gain heat from the surrounding in the shopping mall.Thus, he feels hot.

My apologies for the extended delay in responding to the forum topics. I was caught up with work and a toddler approaching his terrible twos and really couldnt spare time to visit the forum. But thanks again to the moderators not deleting the topic.
I'll try to answer as many backlogged questions as possible. -

Personally, I like the PSLE Ultimate Science Guide by EPH for the following reasons.
1. It is comprehensive (it is a giant book and for $19.90 you can certainly use it for at least 4 years, if you purchase it for your primary 3 child)
2. It has concept maps and examination tips, 2 things that you need in emergency preparations for exams.
3. A glossary, which your child can use to remember definitions.
There are more books but this is just my personal preference.
Hope this was helpful! -

Key words are important in answering Science questions. Try getting your child to underline or highlight the key words in her open-ended answers. If she cannot find key words such as heat gain or heat loss etc... she's probably too general in her statements.
E.g. Answer: John's body temperature was lower than Mary and the surrounding temperature (Must show comparision) so he experienced heat gain from the surroundings unlike Mary who experienced heat loss to the surroundings. -
Hi Niedino,
What are some of the better science assessment books out there? -

Hi Kayelinht, you may refer to a separate thread on Science Assessment Books: http://www.kiasuparents.com/kiasu/forum/viewtopic.php?f=27&t=19568&p=411345&hilit=science+assessment#p411345Hi Niedino,
What are some of the better science assessment books out there?
For me, I like Teachers@work.

For guide books, I prefer the My Pals PSLE Guide as it is in line with the texts and activity books that most schools are using.

Hi moderators and monitors,
I was looking through the posts and it has deviated somewhat from my original intentions. I was and am still a newbie at forum posting. I find it a little difficult now to post up new misconceptions about Science as I do not want them get lost. Should I blog or submit articles instead?
