I'm a student.


Can anyone tell me what is going to happen for Science when I am P3? :?

Nothing, except you have an additional subject called Science to study for exam. :lol:
You will be studying the lower block Science which is meant for p3 and p4.

Thank you for telling me.

Question: Heather and kate were discussing if the clock is a living thing. Kate felt that the clock is a living thing because it is able to move on its own. Was Kate correct? Give a reason for your answer. (1mark)


Child’s Answer: No. Because a clock does not need air, food or water. All living things need air, food and water to survive.

Answer Key: No. Because the clock does not reproduce, grow and does not need air, food and water.



When answering such above questions as in defining what is a living thing, is it mandatory to list down all characteristics of Living things to get full marks? If yes, should we also include clock cannot response to changes around them and clock cannot die?

Child's answer for
(b) A is a non-living thing while D is a living thing.
(c) It needs air, food and water and it grows.


Answer key for
(b) A does not grow but D can grow.
(c) C grows but does not move freely.



Both questions did not state, \"from the flow chart above\" in their question, so is it wrong to infer/conclude that A is a non-living thing and D is a living thing based on the flowchart? Or should all such questions be answered in accordance to what is stated in the flowchart?

Hi

Q20 tells a student to study the flowchart below.

Therefore, one should derive the differences in characteristics from the given chart instead of relying on prior knowledge.

Hello....I need help to understand the concept and why the expected answer to the question for part (b) below.


This is how the question goes:
http://postimage.org/image/2673bkczo/

This is the given answer :
http://postimage.org/image/2jfzm7tc4/

With reference to part (b), the answer seems to be just repeating what the graph is showing instead of explaining why organ S has the most amount of food digested. Is this the expectation in an answer for all such questions? ** Please help ****

Hi usaik


In PSLE Science, students learned that the digestive system comprises the:

-Mouth
-Gullet
-Stomach
-Small intestine
-Large intestine
-Anus

Digestion begins in the mouth. It is completed in the small intestine.

The question asks a student to explain why and one is expected to give the reason/cause on why something happened.

My suggestion is to keep within the syllabus. I think it’s good enough to explain that more digested juices are added in the small intestine and digestion is completed in the small intestine.

(My answer is based on information from the old edition of PSLE Science Guide, please refer to your current textbook/guidebook to see if more information is added)

Merry Christmas and a Happy New Year.

Hi Tianzhu,


Thank you so much for taking time to provide all the explanation. Looks like the answer key is not to be trusted fully.

MERRY XMAS & A HAPPY NEW YEAR TO YOU TOO!!!
