MISCONCEPTIONS


A misconception is a view or

opinion that is incorrect

because it is based on faulty

thinking or understanding.


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


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


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


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


*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

Science is everywhere around us.

Remember…

*Be observant and your child will be too

*Ask your child questions

*Seek answers together

*Make every journey with your child a

journey of discovery



1. Read the questions carefully and know the

requirements of the question

2. Study the diagrams / table of results / graphs if

any

3. Identify which topic the question comes under

4. Think of the concept(s) involved

5. Think of the key word(s) to use

6. Write the answer by using key word(s) to express

the concept(s)

7. Be specific in the answer


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


*Pupils do not understand the requirement of the questions

*Poor Answering techniques

- Incomplete answer

- Dependent questions

- Comparison questions

- Not answering directly to the question

- Use of pronouns

- Lack of specific answer


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


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)


hole

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.

ContainerTemperature of air inside the

container (°C)

A 27

B 36


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)


Height of the content

in the capped

container (cm)

Start of experiment 10

End of experiment 12

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
