* The nature of different
environments-Forests, Plains, Hills, Ponds, Rivers, Seas and Deserts
Our earth has different land forms and
water bodies like forests, plains, mountains, hills, deserts, rivers and seas.
There was a big celebration in school for
the National Children‛s Science Congress. Everybody
was excited. Students had come from many schools from all over India. They introduced themselves
and spoke about the places they had come from.
Daniel said,”I live near a forest.
A forest has a large number of trees. The ground is covered with bushes and grass. Streams and ponds are also found in the forest. It is home to many animals like elephants, tigers, deer, lions, bears and snakes. Birds like peacocks, doves, sparrows, parrots and woodpeckers live there. You can hear the different sounds of animals. I like the forest. It is cool and shady”.
The age of a tree can be
found by counting the number of annual growth rings in its trunk.
Forests are useful to us in many ways.
We get wood, honey, fruits, rubber and many other things from forests.

Some birds found in forests can also be
seen near our houses. Put
a tick (✓) mark for the birds that you have seen.
Plain and Hill
Tharun said, “I come from a farming family.
We live in the plains. A plain is a flat
land area. It is warmer than the hills. Plains are important for growing crops.
Without growing crops, how can we get our food?
Farms get water from the rain, rivers,
lakes, ponds and wells. We find many animals like cows, goats, bullocks, buffalo
and many kinds of birds there. I like to watch the birds”.
Kamakshi said, “I live in the hills.
A hill is like a mountain but not so high.
Hills are generally green and beautiful. It is also much cooler than the plains.
People visit the hill stations especially in summer”.
Word list: hill, hill station, summer, farming, crops, step farms
Look at this picture. This hill looks as
if steps have been made on it. Crops are grown in the step farms, also called as
terrace farms. Tea and coffee are grown on some hills.
Udhagamandalam (Ooty) is called the ‘Queen‛ and Kodaikanal is called the ‘Princess‛
of the hill stations in Tamil Nadu.
Our state animal, the Nilgiri Tahr, is found in the Nilgiri mountains.

Sulaiman said, “I would like to speak
about the pond in my
village. A pond is a place where water
collects. It gets filled by rain.
Fishes, insects, snakes, frogs, crabs and turtles live in a pond. Flowers like water
lily and lotus are also found in ponds. A lake is bigger than a pond”.
Draw the fish as given below
and colour it.
River and Sea
Sultana said, ”I live near a river. I love to watch the river
flowing. It starts its journey on a
mountain, follows a path and finally flows into the sea.
Word list: river, sea, path, boat race,
We use river water in many ways. Because
of this, in olden days, people lived near rivers. Many kinds of fishes, crabs and
birds live in and around the river. Sometimes boat races are also held in the river.
My brothers like to participate in the boat races”.
Journey of a River
Gopal said, “I belong to a family
of fisher folk. We live near the sea.
A sea is a large water body. The sea water is salty. We get salt from the sea. Plants, fishes, turtles, prawns and crabs live in the sea. We go fishing in the sea using fishing boats called Catamarans (Kattumaram) and fishing nets”.
We get pearls from oysters.

Word list: desert, sandy, quiet, sand
Mewa Ram and Kamala said, “We come from a desert area. A desert is a hot and sandy
place. There are hills of sand called sand dunes. The Cactus plant grows in the
desert since it needs very little water to live.
Camels are used for travelling in the desert.
The camel is called the ‘Ship of the Desert‛. Since we have very little water, we
use it carefully”.
All the students were happy to know about
each other‛s homes and surroundings. They became aware that they were a part of
nature. They took a pledge to care for the environment and the natural life around
them. Shall we also take such a pledge?
The camel can drink a large
amount of water at one go. It can live without food and water for many days.
Colour the ones which belong
to a desert.
