How Differentiated
Curriculum Had Helped the
Pupils
• Teachers are able to be more focused in providing the
appropriate help to the class.
• All the pupils can learn as a class at the correct pace for
every subject.
• Every pupil can be equally challenged by their
peers within the class.
• Every child’s social circle is widen as they get to make
more friends from different classes
One area of concern
Pupil’s weaknesses in :
• analyzing Science questions & diagrams
with understanding
• answering questions specifically with
correct keywords in scientific terms and
concept(s)
• Being specific with phrasing of answers eg.
Use of “It” or “They”.

Misconception/Incorrect Answers
(Qns on “How”)
How – Explain the process / methods / way
sunlight
• Qn 31b:How does the condition stated in (a) help the plant
and animals to survive?
• Pupil’s Answer:
The plant can photosynthesise to make food in the presence
of sunlight and give out oxygen.
• Correct Answer:
The plant photosynthesises in the presence of sunlight
and produces oxygen for the animals/lizard and flies to
respire.
(Processes ‘photosynthesis’ and ‘respiration’ must be stated.)

(Qns on “How”)
How – Explain the process / methods / way
sunlight
• Qn 31b:How does the condition stated in (a) help the plant
and animals to survive?
• Pupil’s Answer:
The plant can photosynthesise to make food in the presence
of sunlight and give out oxygen.
• Correct Answer:
The plant photosynthesises in the presence of sunlight
and produces oxygen for the animals/lizard and flies to
respire.
(Processes ‘photosynthesis’ and ‘respiration’ must be stated.)
Misconception/Incorrect Answers
(Qns on “What”)
What – Refers to a specific noun (object, events,
actions)
• Qn 31c: What is the purpose of the limewater in
the experiment?
• Pupil’s Answer: To test for the presence of
carbon dioxide.
• Correct Answer: To test if carbon dioxide is
produced by the animals (lizards and flies).
(Based on the diagram shown.)
Misconception/Incorrect Answers
(Qns on “Why”)
Why – reason / cause and effect
• Qn 38b: Explain why the ball slowed down and
eventually came to a stop on its own.
• Pupil’s Answer: Frictional force slowed down the ball
(merely stating a fact without any explanation of
scientific concepts as reasons)
• Correct Answer: Frictional force between the moving
ball and the surface of the floor slowed down the
ball and caused it to come to a stop on its own.
Misconception/Incorrect Answers
(Qns on “How”)
How – Explain the process / methods / way
• Qn 33a: Animals like the frog and crab can live both on land
and in water.
Write in the boxes providing the details on how these
animals are adapted to breathe in water and on land.
• Pupil’s Answer: Frogs breathe through gills in water and
skin on land (adult frogs don’t have gills anymore,
confused knowledge with tadpoles)
• Correct Answer: Frogs breathe through its skin, taking in
dissolved oxygen in water. On land, frogs breathe in
air through its lungs and moist skin.
(Avoid one-word answer, elaborate on the details)
Misconception/Incorrect Answers
(Qns that requires Comparison)
• Qn 40a. Sean and Ahmad were each given a ball of plasticine
during an art lesson. They made the following statements
after playing with the plasticine.
Sean: A force caused my plasticine to become smaller.
Ahmad: A force helped me turn the ball of plasticine into a cube.
Whose statement(s) about force is correct? Explain why.
• Pupil’s Answer: A force can change a ball of plasticine into a
cube
• Correct Answer: A force changes the shape of an
object but it does not reduce the mass/ size of an object.
Misconception/Incorrect Answers
(Qns on Diagrams/Analytical Qns)
• Qn 40b:Mr Tan was driving in Car B at 60 km/h on a
rainy day. He stepped on the brakes that were in good
working condition. The car skidded and crashed into
Car A as shown below. The front parts of both cars were
badly damaged.
Misconception/Incorrect Answers
(Qns on Diagrams/Analytical Qns)
• Qn 40b:
i) Why did Mr Tan’s car skid?
• Pupil’s Answer: Tyres are worn out / road is
slippery (stating a fact, not explaining)
• Correct Answer: Water reduces the friction
between the tyres and the road / brakes and
wheels that cause the car to skid.
Misconception/Incorrect Answers
(Qns on Diagrams/Analytical Qns)
• Qn 40b: ii) If Mr Tan were to drive at 100 km/h,
compare the damage on the 2 cars. Explain your
answer.
• Pupil’s Answer: Cars are badly damaged.
(Pupils did not make comparison)
• Correct Answer: Increasing the car’s speed
increases the impact / force on the cars and the
damage will be greater/ worse.
Pre-PSLE Science Preparation for each pupil
• Assess which topic(s) that you don’t understand.
• Re-learn / revise that topic(s) via AsknLearn portal,
past Textbks or from Internet websites.
• Practice and try to complete at least one whole Science
exam paper within 1 h 45 mins per week at home
(without any breaks in-between)
• Aim to score full marks (60/60) for Section A by
reading the 4 given options carefully and choosing the
most suitable answer.
• For Section B, read through quickly ALL 14 questions.
Answer ALL those you can answer confidently FIRST.
• Then with the remaining time, ponder and answer
those more difficult ones.
Other “Home-based” Science
Enrichment
• Watch Documentary shows (e.g. “Animal Planet”,
“Animal Night / World”)
• Subscribe to Science magazines (e.g. National
Geographic or Young Scientist magazines)
• Observe the different types of items in a
supermarket (e.g. fish, fruits, vegetables, spices)
• Go for nature walks (e.g. parks, beaches)
• Talk to your child about Science all the time.
All Parents, please take note:
•Topics covered in P3, P4, P5 and
P6 will be tested in PSLE and
Prelim.
