Who has got my ears…

Are these animals looking funny. The artist has drawn wrong ears on

the heads of the animals. Give correct ears to the animals in the space

given below.

Different animals have different kinds of ears

We can see the some of the animals ears.

We cannot see some of the amimals ears.

All the animals have ears even though we cannot see the ears.

Observe the animals ears carefully.

An animal with ears like fans

An animal with ears like leaves

An animal with ears on the top of its head

An animal with ears on both sides of its head

You know very well that ears help us to hear. In some animals you can see the ears, in some you can not. 

We can not see a bird’s ears. A bird has tiny holes on both sides of its head. Generally, the holes are covered with feathers. If you look carefully, A bird have tiny hole on each side of its head. The hole are generally covered with feathers.They help the bird to hear.

Animals like lizard crocodile etc also have tiny holes as ears but we cannot see them.

Whose Skin:

Now you know how to recognise animals by their ears. Let us see if we can recognise animals by their skin. The different patterns on the animals are due to the hair on their skin.

Have you ever seen an animal without hair or whose hair have been removed? Imagine how the animal would look if it did not have any hair on its skin. The different patterns on animals skin are due the hair on their skin.

So, what did you note? Those animals whose ears you can see have hair on their body. Then how these animals increase number.

Those animals that whose ears we can see,have hair on their body. These  animals directly give birth to young ones we called them as viviparous.

Ex: cow, dog cat….

These animals give birth to the young ones. Those animals that do not have ears on the outside, do not have hair on their body. These animals lay eggs. We called as oviparous.

Ex: birds, hen, lizard.

GOING TO SCHOOL

ENVIRONMENTAL STUDIES

CLASS IV – CBSE

Let us meet some children and see how they reach school…

Bamboo Bridge - Assam:

It rains so much where we live. Sometimes after the rain, there is knee-high water everywhere. But that does not stop us from getting to school. We hold our books in one hand and bamboo with the other. We quickly cross the bamboo and rope bridge to reach school.

The Trolley- Ladakh:

Everyday we have to cross the river to get to school. The river is wide and deep. There is a strong iron rope across the river. On both the sides it is tied tightly with strong trees or rocks. There is a trolley (an open box made of wood) attached with the rope. Four or five of us sit in the trolley. A pulley helps the trolley to move across the rope. We reach the other side of the river in a short time.

Cement Bridge:

We often need to go across some water bodies, so we use bridges. These are made of cement, bricks and iron rods. The bridgemay also have steps.

In some parts of Kerala, we use a vallam (small wooden boat) to reach school. Kerala.

Camel-cart Rajasthan:

We live in the desert. There is sand all around. It gets very hot in the day. We ride in a camelcart to reach school.

Bullock-cart- Village in the plains:

We ride in our bullockcart, going slowly through the green fields. If it is too sunny or raining, we use our umbrellas. 

Bicycle ride:

We ride our bicycles on the long road to school. At first, girls here did not go to school, because it was too far. But now groups of 7-8 girls easily ride even through the difficult roads.

Jugad - What a Vehicle!

Look at our special transport. It sounds phut-phut-phut when it runs. Is it not something special! The front looks like a motorcycle but the carriage at the back is made out of planks of wood.

Children cross the Jungle:

We have to go through a thick forest to reach school. At some places, it is so thick that even sunlight does not pass through. It is also very silent there, you can only hear the sounds of different birds and other creatures.

Moving on the Snow:

See, how we reach school! We go to school through miles of snow. We

hold hands and walk carefully. If the snow is soft, our feet sink into it. When the snow is frozen, we may slip and fall-Northern Hills.

Rocky Paths- Uttaranchal:

We live in the mountains. The paths are rocky and uneven. The children who live in the plains will find it difficult to walk on these. But we can easily race up and down.
