CRITERIA IN SECTION B

Observation

Look at

State the logical observation

State the differences between the pictures given

Picture / figure

Observation

State one observation based this picture

Size of leaves / stem is bigPlant have many leaves

ObservationGlass paper Ceramic plastic

Mass ( g) 10 20 15

Figure 1 shows three glasses that are made of different materials.

The mass of the three glasses are measured with compression

balance. The results of the investigation are recorded in Table 3.

The mass of ceramic glass is more than paper and plastic glass

The mass of glass is different

Give reason for the situation

Inference

Look at

State the differences between the pictures given

State the observation

Picture / figure

Observation and inference

Observation : Size of leaves / stem is big

Inference : The plant get enough fertilizer

Observation : Plant have many leaves

sunlightwaterspace

Observation and inference

Observation : Living things needs water

Inference : To stay alive

Inference : To maintain the body temperature

Observation and inference

State the observation based on this picture

Cow eat grass compared with tigerCow eat grass, tiger eat meat ( other animal)

inference

Cow is hervivores, tiger is carnivores (aras tinggi)

Cow is herbivores compared to tiger (aras rendah)

Condition in the room ( cold / hot)

Number of pupils in the room

Condition in the room

1 Too cold

5 cold

10 hot

15 Too hot

To investigate the relationship between _______ and __________________

To investigate the relationship between number of pupils in the room and the condition of the room

Aim / purpose

What to change

Condition of the plant

To investigate the relationship between number of seedlings in a pot and

the condition of the plants

Identify the variables

What to change

What to observed Height of the plant /

Size of the leaves/ stem

What to keep the same

Place the plant been planted

Type of plant / amount ofwater , fertilizer …

Identify the variables

What to change

What to observed

What to keep the same

Size of magnet

Size of leaves

size of paper clip

Number of paper clip attracted

Pupil Total of steps

Q 35

R 40

S 45

T 50Table 1 shows the total of steps used by five pupils to measure the length

of badminton court

Hypothesis

The (more / less) the _________ themore ( lesser ) the ______________

wtc

wto

The more the height of pupil the lesser the total of steps

The lesser the height of pupil the more the total of steps

If the pupil is shorter, the total steps are the most compared with the tallest pupil.

Aras tinggi

Hypothesis

What to change

What to observed

Size of magnet

Size of leaves

Number of paper clip attracted

The more the size of magnet the more the numberof paper clips

The more the size of magnet the more the numberof paper clips attracted

Length of the string (cm)

10 15 20 25

Number of the pendulum swings 31 26 21 16

The more the length of the string the less the number of pendulum swing.

If the length of the string is increase, then the number of pendulum swing is decrease

Number of pupils in the room

Condition in the room

1 Too cold

5 cold

10 Too hot

15 hot

The more the number of pupils in the room the more hotter the condition in the room.

If the number of pupils in the room increase, the condition in the room is getting hot.

the temperature
