Q&A - P3 Science

[janet88]

Hi E3,

I can only give you a guideline what topics were covered during the past 2 years…provided MR Science HOD doesn’t change anything.

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.

Best wishes

Hi tianzhu

What is the difference between the 1st edition and the 2nd edition? I bought the PSLE science guide for my elder boy when he was in P3 2 years ago. Now when my younger one is going to P3 next year, its already 2nd edition.

[quote=\"E3\"]Hi all,


I am not very familiar with the topics for the new syllabus. Does all school start on the same topics at P3? Thanks. :?

No. This is because Science for primary school is divided into lower (P3-4) and upper (P5-6) blocks. Schools can decide the arrangement of topics within each block.

The easiest way to tell which are the topics that will be covered at P3 is to check with the relevant school directly.

Thanks! So as long as all the themes for P3 and P4 are taught within these two years, and the rest taught in P5 and P6, the sequence does not matter?[/quote]Yes E3, that's right.

If you download the <b><a href=\"http://www.moe.gov.sg/education/syllabuses/sciences/files/science-primary-2008.pdf%22%3EPrimary Science Syllabus</a></b>, you will find the topics that will be covered at each block on page 10.

Hope that helps.

Hi sharmila

I am not too sure as I don’t have a copy of the second edition.

Some topics such as The Solar System, Simple Machines, etc are not covered in the new syllabus.

For current students, it’s good to refer to the latest copy of the science guide.

Best wishes

Yes, Uncle tianzhu is right.
The 2nd edition is tailored and reorganised to suit the current PSLE Science syllabus ie section A on the revision notes based on different themes (Lower/Upper blocks).Section B (Process Skills) and Section C (Case studies) remain the same.

Section A (Revision Notes)
Theme: Diversity
Level: Lower Block
Chapter: Classifying Things, Living and Non-Living Things, Plants, Animals, Fungi and Bacteria, Exploring Materials.

Theme: Cycles
Level: Lower Block and Upper Block
Chapter: Life Cycles, Matter And Its Three States, From Parents To Young, Reproduction In Plants, Reproduction In Animals, Water And Changes of State

Theme: Systems
Level: Lower Block and Upper Block
Chapter: What Is A System? Your Amazing Body, The Digestive System, Plants and Their Parts, The Plant Transport System, Air And The Respiratory System, The Human Circulatory System, The Unit Of Life, Electricity

Theme: Interactions
Level: Lower Block and Upper Block
Chapter: Magnets, Forces, Living Together, Characteristics Of The Environment, Food Chains And Food Webs, Adaptations For Survival, Man's Impact On The Environment

Theme: Energy
Level: Lower Block and Upper Block
Chapter: Light, Heat And Temperature, Energy In Food, Forms, Uses And Sources Of Energy

There were some Science guide books and assessment sold at Popular roadshows earlier...bought some of them, thinking I landed a good deal...until I realized they were old syllabus

'Diversity', 'The Solar System' are not taught in upper primary...now stuck with a pile of old books.

Container Y filled with marbles.
Container Z filled with water.

The above is a common diagram found in most P4 past exam papers.

Question: If the water of Container Z is poured into Container Y, some water will be able to flow in. Explain why water can flow in?

My son's ans was: There are spaces between the marbles hence water is able to flow in.

The school marked him wrong and the given answer was Water has replaced the space taken up by the air.

The answer provided by the school is according to PSLE standard...although I do understand what your son is trying to explain...have this problem explaining to son too. School wants PSLE standard answer.

Hi,

Here are my suggested amendments:

There are air spaces between the marbles hence water is able to flow in to take its place.


Keywords -

air between marbles,

water replaces the air or
water takes the place previously occupied by the air
