Questions and Solutions

Question 1

The artist has drawn wrong ears on the heads of the animals. Give correct ears to the animal in the spaces given below.

Animal Ears Animal Ear

Elephant Mouse Dog Rabbit Buffalo Mouse Deer Giraffe

Giraffe Elephant

Solution:

This question requires matching the correct ears to the respective animals. Let's provide the correct pairings:

Elephant: Large, fan-like ears.

Mouse: Small, rounded ears.

Dog: Ears can vary, but typically floppy or pointed, located on the sides of the head.

Rabbit: Long, leaf-shaped ears that stand upright.

Buffalo: Medium-sized ears, often broad.

Deer: Large, mobile ears, often pointed.

Giraffe: Horn-like ossicones and small ears located on top of the head.

The provided answer in the source lists the animals and their ears. We will present it in a clearer format:

Animal: Ears

  • Elephant: Large, fan-like ears
  • Mouse: Small, rounded ears
  • Dog: Ears on the sides of the head
  • Rabbit: Long, leaf-shaped ears
  • Buffalo: Broad ears
  • Deer: Large, pointed ears
  • Giraffe: Small ears on top of the head

Question 2

Different animals have different kinds of ears. Among the animals given below, which ones have ears that you can see? In which animal can you not see the ears? Write in the table.

Deer Frog Fish Ant Crow

Tiger Sparrow Buffalo Snake Lizard

Duck Giraffe Elephant Cat

Solution:

We can observe that some animals have prominent external ears that are easily visible, while others have ears that are not easily seen, often being small or hidden under their skin or feathers.

Animals with ears that we can see:

  • Deer
  • Tiger
  • Buffalo
  • Giraffe
  • Elephant
  • Cat
  • Dog (implied from previous question)
  • Rabbit (implied from previous question)

Animals with ears that we cannot see (or are not easily visible):

  • Frog
  • Fish
  • Ant
  • Crow
  • Sparrow
  • Snake
  • Lizard
  • Pig
  • Duck

Question 3

Do you think that the animals whose ears we cannot see really do not have ears?
Solution:

No, it is incorrect to assume that animals whose ears are not visible do not have ears at all. Most animals have ears, but their structure and location can vary greatly. For animals like birds, fish, frogs, and reptiles, their ears are often internal or covered by small openings that are not easily noticeable. These hidden ears function perfectly well for hearing.

Question 4

Name the animals in the picture.

(Picture is not provided in the text, but common animals found in such contexts are listed.)

Solution:

Based on the context of typical EVS lessons and the animals mentioned later in the chapter, the animals likely depicted in the picture are:

  • Hen
  • Sparrow
  • Duck
  • Parrot
  • Crow
  • Frog

Question 5

Can you see their ears?
Solution:

No, for most of the animals listed (like hen, sparrow, duck, parrot, crow, and frog), their ears are not visible externally. They have small ear openings that are usually hidden by feathers or skin.

Question 6

Find out some other animals which have ears that we cannot see. Write their names.
Solution:

There are many animals whose ears are not easily visible. Some examples include:

  • Swan
  • Fish
  • Fly
  • Mosquito
  • Crocodile
  • Snake
  • Lizard
  • Ant
  • Termite
  • Whale

These animals have ears that are either internal or are small openings that are not externally prominent.

Question 7

An animal with ears like fans:
Solution:

The animal with ears that are large and spread out like fans is the Elephant. These large ears help the elephant to radiate heat and keep its body cool.

Question 8

An animal with ears like leaves
Solution:

The animal described as having ears shaped like leaves is the Rabbit. Its long, upright ears resemble the shape of leaves and are very sensitive to sound.

Question 9

An animal with ears on the top of its head.
Solution:

While rabbits have ears that stand upright, the description "on the top of its head" could also apply to animals like the Giraffe, which has small ears and ossicones located on the top of its head. However, if the context implies ears that are prominent and leaf-like, then Rabbit is also a fitting answer as its ears are positioned on top of its head and stand erect.

Question 10

An animal with ears on both sides of its head.
Solution:

Animals that have ears located on the sides of their heads are very common. A typical example is the Dog. Many mammals, including dogs, cats, horses, and humans, have ears positioned on the sides of their heads, allowing for directional hearing.

Question 11

Now you know how to recognize animals by their ears. Let us see if we can recognize animals by their skin. Match the animals shown here with the pictures of their skin. Make the correct pattern of the skin on the picture of each animal.

(Note: This question requires visual matching of animal images with skin patterns, which cannot be performed with text alone. The solution describes the general concept.)

Solution:

This exercise is about observing the unique patterns on the skin or fur of different animals and matching them to the correct animal. For example:

  • A tiger has stripes.
  • A zebra has black and white stripes.
  • A leopard or cheetah has spots.
  • A cow or buffalo has a patterned hide.
  • A snake has scales with patterns.

To answer this question, one would look at the distinct patterns (stripes, spots, patches, scales) on the animal's skin or fur and match it to the corresponding image of the skin pattern provided. The goal is to understand that each animal has a unique skin covering that helps in its identification.

Common mistakes

  • Confusing animals with similar-looking ears.
  • Assuming animals without visible ears do not have ears at all.
  • Difficulty in matching animals to their correct skin patterns.

Revision tips

  • Draw different animal ears and try to identify the animals.
  • Create a chart comparing animals with visible and hidden ears.
  • Practice matching animal pictures with their skin patterns.
  • Discuss with friends or family about the ears of animals you see around.
