Q10: Starting from the first letter, strike out every alternate letter in the given letter group to find out the name of an animal. 
K M T O J S N Q S U P I T T O O P 
Now, select the option which correctly describes how this animal eats its food.
(a) Lapping
(b) Swallowing
(c) Chewing
(d) Sucking

Science Olympiad Model Test Paper - 3 | Science Olympiad for Class 3  View Answer

Ans: (d)

  • To find the animal's name, we take the letters K M T O J S N Q S U P I T T O O P and remove every alternate letter, starting from the first. This gives us the letters O, J, S, Q, U, T, O, O, which spells "octopus".
  • Octopuses are known for their unique way of eating, which involves using their tentacles to bring food to their mouths.
  • The correct option that describes how an octopus eats is sucking, as they use their beak to suck in food.
  • Thus, the answer is (d) Sucking, as it accurately describes the feeding method of the octopus.

(c) Complete digestion of food takes place in the stomach.
(d) Spinal cord is a part of the nervous system.

Science Olympiad Model Test Paper - 3 | Science Olympiad for Class 3  View Answer

Ans: (c)

  • Complete digestion of food does not occur in the stomach; it mainly happens in the small intestine.
  • The stomach is responsible for breaking down food and mixing it with digestive juices, but it does not fully digest it.
  • The small intestine is where most nutrients are absorbed and where the final stages of digestion occur.
  • Therefore, option (c) is the incorrect statement among the choices provided.

Q13: Select the option that accurately matches a planet with a constellation.
(a) Neptune, Moon
(b) Jupiter, Orion
(c) Mars, Uranus
(d) Sun, Scorpius

Science Olympiad Model Test Paper - 3 | Science Olympiad for Class 3  View Answer

Ans: (b)

  • Jupiter is a planet that is often associated with the constellation Orion in various astronomical contexts.
  • The other options do not correctly pair a planet with a recognized constellation.
  • For example, Neptune is not paired with the Moon, and the Sun is not a planet but a star.
  • Thus, the correct pairing is Jupiter with Orion.

Q14: __________ is a standard unit for measuring length.
(a) Handspan
(b) Cubit
(c) Footspan
(d) Metre

Science Olympiad Model Test Paper - 3 | Science Olympiad for Class 3  View Answer
