MISCONCEPTIONS
JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.
A misconception is a view or
opinion that is incorrect
because it is based on faulty
thinking or understanding.
JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.
COMMON
MISCONCEPTION
SCIENTIFIC CONCEPT
Clouds are made of
water in the gaseous
state, i.e. water
vapour
Clouds are made of tiny
water droplets. It is the
result of condensation
as water vapour changes
to water droplets at a
cooler temperature
JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.
COMMON
MISCONCEPTION
SCIENTIFIC CONCEPT
Photosynthesis takes
place during the day
and respiration takes
place at night
Photosynthesis takes
place in the
presence of light.
Respiration takes
place all the time in
the cells of living
things
JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.
COMMON
MISCONCEPTION
SCIENTIFIC CONCEPT
Coldness travels from
a cube of ice to your
hand, making your
hand feel cold
Heat travels from a
warmer area to a
cooler area. The hand
feels cold because
the hand loses heat
to the ice cube
JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.
COMMON
MISCONCEPTION
SCIENTIFIC CONCEPT
When iodine is dropped
onto some bread, the
bread turns blue.
Iodine is used to test for
the presence of starch.
If iodine, which is
yellow, turns blue,
starch is present in the
item tested.
N.B. When iodine is
dropped onto bread,
the iodine turns blue.

Science is everywhere around us
*Be observant
*Ask questions
*Seek answers together
*Make every journey with your
child a journey of discovery
JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.
*There are many examples of simple everyday
occurrences which pupils need to be observant
about and to relate conceptual knowledge learnt in
school and apply this knowledge to the real world.
*Parents can assist by
-being aware of the syllabus (check MOE website)
-helping to connect the school experience with the
real world experience

STATE Give a concise answer.
No explanation required.
EXPLAIN/DESCRIBE Give relevant details.
Use ‘first’, ‘next’, ‘then’.
WHAT WOULD HAPPEN? Involves scientific reasoning or
reference to science concepts
No one-word answer, can be a 2 mark
question
WHAT DOES THE DATA / EXPERIMENT
TELL YOU?
Analyse and / or interpret information
(inferring)
Use comparatives (largest/most,
smallest/least, etc.) when necessary

Explain clearly how the seed of Plants X and Y are dispersed. [2]
Pupils’ Answer:
Plant X: It can be eaten
Plant Y: It has a wing like structureA need to state the
characteristic of the seed
and how it helps in dispersal
JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.JING SHAN PRIMARY SCHOOL THINKERS. LEARNERS. LEADERS.
Answer
(b) X: It has a fleshy outer covering that can be eaten (½
m) and the seeds are thrown away/passed out with the
animal’s droppings. (½ m)
Y: It has a wing-like structure (½ m) that helps the seed to
stay airborne longer/carried away by the wind. (½ m)

Ravi wants to drain out sweetened milk from a tin into a mug. He
wants to see which way is faster. So, he pokes one hole at the top,
using a can opener for Tin A. For Tin B, he pokes two holes at the
top as shown below. Then he tilted Tin A and Tin B.
Which tin will drain out the sweetened milk faster? [1m]
_____Pupils’ Answer: Tin A Answer: Tin B
b) Explain your answer in (a). [2m]
This is because there are two holes in Tin B. Air will enter through one of
the holes and occupy the space(1m) inside the tin and it will push the milk
out through the other hole.(1m)

What is the difference in the blood at points X and Y in Diagram 2?[1]
Pupils’ Answer:
Blood at point X is rich in carbon dioxide.
Blood at point X contains less oxygen. No comparison
made. Answer:
Blood at point X is rich in carbon dioxide while the blood at point Y is
rich in oxygen.
Blood at point X contains less oxygen than blood at point Y.
Blood at point X is richer in carbon dioxide than blood at point Y.

Gita set up an experiment as shown below using two identical
containers,
A and B. She left both containers under the Sun and measured the
temperature of the air inside each container using dataloggers.
Gita recorded her findings in the table below.

Based on the results above, how does the presence of plants
affect the temperature of the air inside the container?
*Pupils’ Answer:The plants take in light/ The plants absorb
heat.
*Answer: The presence of plants lower the temperature of the
air inside the container.
(Both no link to the decrease in
temperature of air inside the container)

Janet poured water into a container until it reached a height of 10
cm. She then placed the capped container into the freezer. Several
hours later, she removed the capped container from the freezer and
recorded the height of the content in it in the table below.
What is most likely the change of state that the water has gone
through? (1)
Pupils’ Answer: Freezing/Water to solid
Answer: Liquid to Solid
Student should
answer in terms of
the change of state
