(b) There should be a single textbook for the entire country to ensure parity and avoid confusion
(c) It should always be borne in mind that textbooks are essentially meant for teachers' usage
(d) There should be opportunities for learners to appreciate how the concepts of science evolve with time
Show Answer & Explanation
Answer: (d) There should be opportunities for learners to appreciate how the concepts of science evolve with time
Explanation:
1. India is diverse, so examples must reflect varied backgrounds, not only middle income families.
2. Textbooks are meant for learners, and a single national textbook is not required.
3. Showing how science evolves is consistent with the nature of science and NCF.
Teacher's Note:
1. NCF 2005 asks for contextual, inclusive and learner-centred books.
2. Avoid options with 'only' and 'always'.

(a) The percolation rate of water in clayey soil is higher than that of loamy soil
(b) The percolation rate of water in loamy soil is higher than that of sandy soil
(c) The percolation rate of water in clayey soil is the same as that of sandy soil
(d) The percolation rate of water in sandy soil is higher than that of clayey soil
Show Answer & Explanation
Answer: (d) The percolation rate of water in sandy soil is higher than that of clayey soil
Explanation:
1. Sandy soil has large particles and big gaps, so water drains quickly.
2. Clayey soil has very fine particles, so it percolates slowly; thus sandy is higher than clayey.
Teacher's Note:
1. Percolation order: sandy > loamy > clayey.
2. Clay holds water, sand drains it.
(a) Scorpion, snake, rat
(b) Frog, snake, hen
(c) Rat, scorpion, penguin
(d) Penguin, frog, kangaroo
Show Answer & Explanation
Answer: (b) Frog, snake, hen
Explanation:
1. Oviparous animals lay eggs: frog, snake and hen do.
2. Rat and kangaroo give birth to young, and scorpions bear live young, so the other sets are wrong.
Teacher's Note:
1. Viviparous: give birth to young ones, e.g. rat, kangaroo.
2. Check each member of a set.
(A) Budding
(B) Binary fission
(a) (A) and (B)
(b) (B) only
(c) (A) only
(d) Neither (A) nor (B)
Show Answer & Explanation
Answer: (a) (A) and (B)
Explanation:
1. Budding (Hydra) and binary fission (Amoeba) both involve a single parent and no gametes.
2. So both are asexual modes.
Teacher's Note:
1. Asexual: one parent, offspring identical.
2. Other modes: fragmentation, regeneration.
(a) It is a non-contact force
(b) It can be attractive as well as repulsive
(c) It is a unique force which only the earth possesses
(d) It is a strong force
Show Answer & Explanation
Answer: (a) It is a non-contact force
Explanation:
1. Gravity acts without the bodies touching, so it is a non-contact force.
2. It is always attractive, acts between all masses, and is the weakest of the fundamental forces.
Teacher's Note:
1. Magnetic and electrostatic forces are other non-contact forces.
2. Gravity is weak but acts over large distances.
(a) It will boil below 100°C
(b) It will boil above 100°C
(c) It will boil at 100°C
(d) It will not boil
Show Answer & Explanation
Answer: (b) It will boil above 100°C
Explanation:
1. Pure water freezes at 0°C, so freezing at -3°C means dissolved impurities lower the freezing point.
2. The same impurities raise the boiling point, so it boils above 100°C.
Teacher's Note:
1. Solutes cause freezing point depression and boiling point elevation.
2. This is why salt is spread on icy roads.
Mouth: Saliva: (i)

(b) (i) Proteins, (ii) Fats, (iii) Digestive juice, (iv) Starch
(c) (i) Starch, (ii) Proteins, (iii) Bile, (iv) Fats
(d) (i) Proteins, (ii) Starch, (iii) Bile, (iv) Sugars
Show Answer & Explanation
Answer: (c) (i) Starch, (ii) Proteins, (iii) Bile, (iv) Fats
Explanation:
1. Saliva acts on starch; gastric juice acts on proteins.
2. The liver secretes bile, which acts on fats.
Teacher's Note:
1. Salivary amylase starts starch digestion; pepsin digests proteins.
2. Insulin is secreted by the pancreas and is not a digestive juice.

To which of the following cities can the above chart belong?
(a) New Delhi
(b) Chennai
(c) Bikaner
(d) Shimla
Show Answer & Explanation
Answer: (a) New Delhi
Explanation:
1. A January minimum of 7.7°C and a May maximum near 40°C show a large seasonal range of the northern plains.
2. Heavy July rain (208 mm) is typical of the monsoon in Delhi; Bikaner is much drier, Chennai warmer and Shimla cooler.
Teacher's Note:
1. Coastal cities have a small temperature range.
2. Rainfall of 200 mm or more in July points to a monsoon region.
(a) The eye forms an erect image whereas the camera forms an inverted image
(b) The camera has a concave lens whereas the eye has a convex lens
(c) The eye sees in three dimensions while a camera sees in two dimensions
(d) The focal length of a human eye is fixed and cannot be adjusted even slightly
Show Answer & Explanation
Answer: (c) The eye sees in three dimensions while a camera sees in two dimensions
Explanation:
1. Both the eye and a camera form inverted real images, and both use convex lenses; the eye's lens focal length can be adjusted by ciliary muscles.
2. The eye with two eyes and the brain gives depth (three dimensions), whereas a simple camera records a flat image, so the analogy fails here.
Teacher's Note:
1. The brain turns the inverted retinal image upright.
2. Accommodation is the adjustment of the eye lens's focal length.
(a) it involves all the senses.
(b) it can cater to large groups.
(c) it can be arranged easily and quickly.
(d) it gives individual attention.
Show Answer & Explanation
Answer: (a) it involves all the senses.
Explanation:
1. On a field trip learners see, hear, touch and smell real things, so all the senses are involved.
2. Software is the one that scales easily, is quick to arrange and can give individual attention.
Teacher's Note:
1. Field trips give direct, first-hand experience.
2. Check each option against what software can do equally well.

(a) A and B
(b) B and C
(c) A and C
(d) A, B and C
Show Answer & Explanation
Answer: (d) A, B and C
Explanation:
1. Evaporation of water from leaves cools the plant (A).
2. The suction it creates pulls water and minerals up the xylem to the leaves (B).
3. Stomata that open for transpiration also allow gas exchange (C).
Teacher's Note:
1. Transpiration pull drives water movement in tall plants.
2. Gas exchange is linked to open stomata, though it is not the main function.
(a) Urinary bladder → kidneys → ureters → urethra
(b) Kidneys → urinary bladder → ureters → urethra
(c) Kidneys → ureters → urinary bladder → urethra
(d) Urinary bladder → kidneys → urethra → ureters
Show Answer & Explanation
Answer: (c) Kidneys → ureters → urinary bladder → urethra
Explanation:
1. The kidneys filter blood and make urine.
2. Urine flows down the ureters to the bladder, where it is stored, and leaves through the urethra.
Teacher's Note:
1. Order: kidney, ureter, bladder, urethra.
2. Ureters carry urine from kidneys; the urethra carries it out.
Assertion (A): Refrigerator pipes are painted with a black colour.

(b) Both A and R are true but R is not the correct explanation for A.
(c) A is not correct but R is correct.
(d) Both A and R are not correct.
Show Answer & Explanation
Answer: (a) Both A and R are true and R is the correct explanation for A.
Explanation:
1. Black surfaces are good radiators, and good absorbers are good radiators.
2. So black pipes radiate heat out quickly, helping to cool the refrigerant; R explains A.
Teacher's Note:
1. Black surfaces absorb and emit heat radiation well.
2. Dark objects heat up quickly in sunlight for the same reason.
A. How much do they grow if we double the amount of water?
B. How much are they growing every week?
Which of the following process skills are developed by these questions?
(a) Controlling variables and observation
(b) Classification and observation
(c) Inference and hypothesis
(d) Observation and classification
Show Answer & Explanation
Answer: (a) Controlling variables and observation
Explanation:
1. Question A changes one factor (water) and watches the effect, which is controlling variables.
2. Question B asks students to measure and record growth, which is observation.
Teacher's Note:
1. Controlling variables = change one thing, keep others the same.
2. Neither question asks for grouping, so classification is out.

2. White blood cells change shape; muscle cells are long and thin; skin cells are flat.
Teacher's Note:
1. Shape suits function.
2. Neurons carry signals over long distances through branches.
(a) Only salt
(b) Only water
(c) Salt, water and heat
(d) Salt and water
Show Answer & Explanation
Answer: (c) Salt, water and heat
Explanation:
1. Neutralisation gives a salt and water.
2. The reaction is exothermic, so heat is also released; option c is the complete answer.
Teacher's Note:
1. Acid + base → salt + water + heat.
2. Option d is incomplete since heat is also evolved.
(a) gravitational force only
(b) gravitational force and air resistance
(c) gravitational force, air resistance and force of propulsion exerted by the thrower
(d) air resistance only
Show Answer & Explanation
Answer: (b) gravitational force and air resistance
Explanation:
1. Once the ball leaves the hand, the thrower's push stops acting.
2. Gravity and air resistance act on it while it moves.
Teacher's Note:
1. A force is not needed to keep an object moving.
2. Common misconception: a force of the throw continues acting.

2. Average speed = 2182/39.33 = 55.5 km/h.
Teacher's Note:
1. Average speed = total distance divided by total time.
2. Convert minutes to a fraction of an hour (20 min = 1/3 h).
When a disease-carrying microbe enters our body, the body produces ____(i)____ to fight the invader. If dead or weakened microbes are introduced in a healthy body, the body fights and kills them, producing these. This is how a ____(ii)____ works to prevent diseases like ____(iii)____.
(a) Antigens, antibiotic, diabetes
(b) Antibodies, antibiotic, arthritis
(c) Antibodies, vaccine, tuberculosis
(d) Antibiotics, vaccine, arthritis
Show Answer & Explanation
Answer: (c) Antibodies, vaccine, tuberculosis
Explanation:
1. The body makes antibodies against invading microbes.
2. Introducing dead or weakened microbes is vaccination, which prevents infectious diseases such as tuberculosis (BCG).
Teacher's Note:
1. Diabetes and arthritis are not infectious, so vaccines do not prevent them.
2. Antibiotics kill bacteria; vaccines build immunity.

(b) (A) and (C)
(c) (B) and (C)
(d) (A) and (D)
Show Answer & Explanation
Answer: (c) (B) and (C)
Explanation:
1. LPG and diesel are fractions obtained on refining petroleum.
2. Coal gas comes from coal, and CNG is mainly natural gas (methane), so it is not a refinery fraction.
Teacher's Note:
1. Petroleum products: petrol, diesel, kerosene, LPG, lubricating oil, paraffin wax.
2. Natural gas occurs with petroleum but is compressed directly as CNG.
(a) Observation
(b) Inference

Explanation:
1. Observation is what is seen directly, whereas this is a general conclusion drawn from observing that magnets repel.
2. Drawing a conclusion from observations is an inference.
Teacher's Note:
1. Observation: seen. Inference: concluded. Prediction: future event.
2. The words 'sure test' signal a conclusion.
(a) Sharing information about the concept
(b) Defining the term 'friction'
(c) Exploring students' existing ideas
(d) Reading the related text
Show Answer & Explanation
Answer: (c) Exploring students' existing ideas
Explanation:
1. Learners already have everyday experiences of friction, such as rubbing or sliding.
2. Exploring these existing ideas is the constructivist starting point for new learning.
Teacher's Note:
1. Prior knowledge is the base for new knowledge.
2. Starting with definitions or reading is a transmission approach.
(a) smog.
(b) excessive use of fertilizers in agriculture.
(c) discharge of industrial waste in rivers.
(d) acid rain.
Show Answer & Explanation
Answer: (a) smog.
Explanation:
1. Smog is smoke plus fog and carries fine particles and irritant gases.
2. Breathing it irritates the airways and causes bronchitis and asthma attacks.
3. Fertilizers and river waste pollute soil and water, not the air we breathe.
Teacher's Note:
1. Match the pollutant to the medium it pollutes: air, water or soil.
2. Acid rain mainly damages buildings, soil and aquatic life.
(a) Increasing the length
(b) Increasing the amplitude
(c) Decreasing the mass of bob
(d) Increasing the mass of bob
Show Answer & Explanation
Answer: (a) Increasing the length
Explanation:
1. The time period is T = 2π√(L/g).
2. T depends only on the length L and g, so increasing L increases T.
3. Mass of the bob and (small) amplitude do not affect T.
Teacher's Note:
1. Remember that T is independent of mass, material and amplitude (for small swings).
2. A common mistake is to think a heavier bob swings more slowly.
