5. Assign 1 mark for each correct answer.

A. Jaws like in Picture 1 are good for eating flesh while jaws like in Picture 2 are good for

eating plants.

B. Answers may vary. Sample answer:

A hen gives us eggs and meat whereas a cow gives us milk.

C. A swing shows oscillatory and periodic motion whereas the movement of the Earth

around the sun shows circular and periodic motion.

6. The plants are beneficial to us because the plants provide us food, air, rainfall, timber and other products are obtained from them. The plants help us in fighting with global warming and also provide rainfall to us. It also helps us in fighting against many harmful diseases by providing herbal plants. It also provide us timber for making furniture and other household goods and also help in providing sports equipments

CRITERIA MARKS

A. Correctly identifies the motion (0.5 marks each)

Correctly writes the difference between the two types of motion (1 mark) 2

B. Correctly identifies the motion (0.5 marks each)

Correctly writes the difference between the two types of motion (1 mark) 2

TOTAL (4 Marks) 4

A.

Examples a. A car turning at a cross

road b. A train moving on a

straight track

Type of motion (Rectilinear/Curvilinear)

Curvilinear Rectilinear

1 difference between these two types of motion

Curvilinear motion is the motion along a curved path

while rectilinear motion is the motion along a straight

path.

B.

Examples a. Motion of a fan b. Motion of the moon

around the Earth

Type of motion (Rotational/Circular)

Rotational Circular

1 difference between these two types of motion

Rotational motion is the motion around a fixed axis

while circular motion is the motion of a body in a

circular path.

2 + 2 = 4

PART II – Long Answer Questions 30 Marks


CRITERIA MARKS

A. Correctly writes 1 nutrient (0.5 marks each)

Writes a logical reason (1 mark each) 3

B. Correctly predicts the results for each test (1 mark each)

Writes the correct conclusion (1 mark) 4

TOTAL (7 Marks) 7

A. Answers may vary. Sample answer:

a. The labourer should eat more carbohydrates because they provide energy to do

physical work.

b. The boy should eat more proteins because they help in the proper growth of the

body.

B. a.

Test Observations

Starch No change in colour/Blue-black colour is not observed

Proteins Violet colour is observed

Fats No oil marks are observed on paper

b. Egg white is rich in protein.

Writes a logical reason (1 mark) 1.5

B. Correctly identifies the conversion of units (0.5 marks each)

Correctly calculates the mass of objects (0.5 marks each)

Writes correct SI units of the converted mass (0.5 marks each)

4.5

C. Correctly predicts the effect 1

TOTAL (7 Marks) 7

1.5 + 4.5 + 1 = 7

3 + 4 = 7



7

A. Weight is not a fundamental quantity because it is dependent on the mass of an object.

B.

Object Mass of the object in SI unit

A 2000 grams brick

1 gram = 1

1000 grams

Mass of brick = 2000 grams

= 2000

1000 kilograms

= 2 kg

A 2 tonnes wooden log

1 tonne = 1000 kilograms

Mass of wooden log = 2 tonnes

= 2 × 1000 kilograms

= 2000 kg

A 450 quintals rice bag

1 quintal = 100 kilograms

Mass of rice bag = 450 quintals

= 450 × 100 kilograms

= 45000 kg

C. The weight of the stone will increase by 2.5 times on Jupiter.


CRITERIA MARKS

A. Correctly explains the types of nutrition (1 mark each) 4

B. Correctly writes how autotrophic nutrition happens (1 mark)

Correctly writes how heterotrophic nutrition happens (1 mark) 2

TOTAL (6 Marks) 6

A.

Type of nutrition How do the plants obtain nutrition?

Photosynthesis A green plant gets its nutrition by making its own food

using sunlight, water and carbon dioxide.

Parasitism A cuscuta plant derives its nutrition from the host plant

by attaching itself to the host with its hook-like

structures.

Saprophytic nutrition Mushrooms feed on dead organic matter by releasing

4 + 2 = 6



8

digestive juices that break it down to simpler

substances.

Insectivorous nutrition A Venus flytrap plant feeds on insects by trapping

them using its leaves.

B. A Venus flytrap shows autotrophic nutrition because it has green leaves. It also shows

heterotrophic nutrition because it feeds on other organisms like insects to obtain

nitrogen.


CRITERIA MARKS

A. a. Correctly writes the difference in the experiments (1 mark each)

b. Correctly identifies the experiment (1 mark)

Writes the correct reason (1 mark)

4

B. Correctly predicts the results (1 mark each)

Writes a logical reason for the prediction (1 mark each) 4

C. Correctly writes the answer 2

TOTAL (10 Marks) 10

A. a.

Experiment 1 Experiment 2

In this experiment, current is passed

through the iron nail to make it into an

artificial magnet.

In this experiment, the iron nail is

rubbed with a magnet several times to

make it into an artificial magnet.

b. Experiment 1 will result in a temporary magnet because the iron nail will lose its

magnetism as soon as the current flow stops.

4 + 4 + 2 = 10



9

B.

Experiments What will happen? Why will it happen?

The 2 magnets will repel or

move away from each

other.

This happens because like

poles of two magnets

always repel.

The iron nail will get

attracted to the magnet.

This is because iron is a

magnetic material.

C. When a magnet is freely suspended, it will spin and come to rest in a north-south

direction. This means that the north pole of the magnet points to the geographic north

and the south pole of the magnet points to the geographic south; thus, helping us to

know the directions.
