WHOSE FORESTS -TEXT



WHOSE FORESTS
ENVIRONMENTAL STUDIES
CBSE-V

Daughter of the jungle
Look at the picture. Where do you think these children are off to, with little bundles on their sticks? When you find out you too would want to go with them!

The children are going to the forest. There they jump, run, climb trees and sing songs in their language called Kuduk. They pick the fallen flowers and leaves, to weave them into necklaces.

They enjoy the wild fruits. They look for birds, whose calls they imitate. Joining them in all this fun is their favourite didi – Suryamani. Every Sunday Suryamani takes the children to the forest.

As they move around, she shows them how to recognize the trees, the plants, and animals. Children enjoy this special class in a forest! Suryamani always says, “To learn to read the forest is as important as reading books.”

She says,”We are forest people (adivasis). Our lives are linked to the forests. If the forests are not there, we too will not remain.”

Suryamani’s story is a true story. Suryamani is a ‘Girl Star’. ‘Girl Stars’ is a project which tells extraordinary tales of ordinary girls, who have changed their lives by going to school.

Growing Up
Suryamani loves the forest since she was a child. She would not take the direct road to school, but would choose the path through the forest. Suryamani’s father had a small field.

Her family used to collect leaves and herbs from the forest and sell these in the bazaar. Her mother would weave baskets from bamboo or make leaf plates out of the fallen leaves.

But now no one can pick up a single leaf from the forest. That is since Shambhu the contractor came there. The people of Suryamani’s village were afraid of the contractor.

Everyone except Budhiyamai. She would say, “We the people of this forest have a right over it. We look after our forests, we don't cut trees like these contractors do. The forest is like our ‘collective bank’ – not yours or mine alone. We take from it only as much as we need. We don’t use up all our wealth.”

Suryanani’s father could no longer support the family on the small land. He moved to the town in search of work. But things did not improve. Sometimes there would be no food in the house.

At times Maniya Chacha (uncle) would send some grain from his small shop to Suryamani’s house. Chacha tried hard and got admission for Suryamani in the school in Bishanpur.

Here they would not have to pay for the fees, uniforms and books. Suryamani would have to stay there and study. Suryamani didn't want to leave her village and forest. But Maniya Chacha was firm.

“If you do not study, what will you do? Go hungry?” Suryamani would argue, “Why should I go hungry? The jungle is there to help!” Chacha tried
to explain, “But we are being moved away from our forests.

Even the forests are disappearing – in their place mines are being dug, dams are being built. Believe me, it is important for you to study, to understand about the laws. Maybe then you can help to save our forests”. Young Suryamani listened, and tried to understand some of what he said

Suryamani’s journey:
Suryamani was filled with joy on seeing the school at Bishanpur. The school was near a thick forest. Suryamani studied hard and passed her B.A. after getting a scholarship.

She was the first girl in the village to do this. While she was in college she met Vasavi didi, a journalist. Suryamani soon joined her to work for the Jharkhand Jungle Bachao Andolan (Movement to Save the Forests of Jharkhand).

This work took Suryamani to far off towns and cities. Her father did not like this. But Suryamani continued her work. Not only that, she also started to fight for the rights of the village people. Her childhood friend Bijoy helped her in this work.

Suryamani had another friend ‘Mirchi’, who stayed with her day and night. Suryamani would share all her thoughts and dreams with Mirchi. Mirchi would listen and say “Keee Keee.” Suryamani had a dream. for her Kuduk community. She wanted all her people to feel proud of being adivasis.

Suryamani’s Torang:
Suryamani was 21 when she opened a centre, with the help of Vasavi didi and others. She called it ‘Torang’, which means jungle in the Kuduk language.

Suryamani wanted that on festivals people should sing their own songs. They should not forget their music and should enjoy wearing their traditional clothes.

Children should also learn about herbs, medicines, and the art of making things from bamboo. Children should learn the language of school but must link it with their own language.

All this happens in the ‘Torang’ centre. Many special books about the Kuduk community and other adivasis have been collected. Flutes and different types of drums are also kept there.

Whenever something is unfair, or if someone is afraid that his land and livelihood would be taken away, they turn to Suryamani. Suryamani fights for everyone’s rights.

Suryamani and Bijoy have got married and work together. Today their work is praised by many people. She is invited, even to other countries, to share her experiences. People of her area are also raising their voice for a new forest law.

Right to Forest Act 2007

People who have been living in the forests for at least 25 years, have a right over the forest land and what is grown on it. They should not be removed from the forest.

The work of protecting the forest should be done by their Gram Sabha. A forest is everything for us adivasis. We can’t live away from the forests even for a day. Government has started many projects in the name of development – dams and factories are being built.

Forests, which are ours are being taken away from us. Because of these projects, we need to think where the forest people will go and what will happen to their livelihood?

Where will the lakhs of animals living in the forests go? If there are no forests, and we dig out our lands for minerals like aluminium, what will be left? Only polluted air, water, and miles and miles of barren land...

Lottery for farming in Mizoram:
You read about the forests of Jharkhand in Suryamani’s story. Now read about forests on the hills of Mizoram. See how people live there, and
how farming is done.

Ding, Ding, Ding.... As soon as the school bell rang Lawmte-aa, Dingi, Dingima picked their bags and hurried home. On the way they stopped to drink water from a stream in a cup made of bamboo which was kept there.

Today not only the children, even ‘Saima Sir’ was in a hurry to get back. Today there would be a special meeting of the Village Council (Panchayat). At the meeting there would be a lottery to decide which family will get how much land for farming.

The land belongs to the whole village, not to separate people. So they take turns to do farming on different parts of the land. A beautiful pot made of bamboo was shaken well. One chit was taken out. Saima Sir’s family got the first chance.

He said, “I am happy that my family gets to choose first. But, this year we cannot take more land. Last year I had taken more and was not able to farm it well. After my sister Jhiri got married and went away it is difficult to manage farming alone.”

Saima Sir asked for ‘three tin’ of land. Little Mathini asked, “ What is three tin of land? Chamui explained, “The land on which we grow one tin of seeds is called one tin of land.” One by one, the village families got their piece of land for farming.

Jhoom farming:
Jhoom farming is very interesting. After cutting one crop, the land is left as it is for some years. Nothing is grown there. The bamboo or weeds which grow on that land are not pulled out. They are cut and burnt.

The ash makes the land fertile. While burning, care is taken so that the fire does not spread to the other parts of the forest. When the land is ready for farming it is lightly dug up, not ploughed.

Seeds are dropped on it. In one farm different types of crops like maize, vegetables, chillies, rice can be grown. Weeds and other unwanted plants are also not pulled out, they are just cut. So that they get mixed with the soil.

This also helps in making the soil fertile. If some family is not able to do farming on time, others help them and are given food.

The main crop here is rice. After it is cut, it is difficult to take it home. There are no roads, only hilly paths. People have to carry the crop on their
backs. This takes many weeks. When the work is over the entire village celebrates.

 People get together to cook and eat, sing and dance. They do their special ‘cheraw’ dance. In this dance people sit in pairs in front of each other, holding bamboo sticks on the ground.

As the drum beats, the bamboos are beaten to the ground. Dancers step in and out of the bamboo sticks, and dance to the beat.

Find out more about the ‘cheraw’ dance. Do it in your class. But be careful and don’t hurt yourself. About three-fourth people in Mizoram are linked to the forests.

Life is difficult but almost all children go to school. You can see some of them here, playfully blowing their leaf whistles! You too have made many such whistles, haven’t you!

A SEED TELLS A FARMER’S STORY - TEXT

A SEED TELLS A FARMER’S STORY
ENVIRONMENTAL STUDIES
CBSE-V
I am a small seed!
I am a small bajra seed. I have stayed in this beautiful wooden box since 1940. I want to tell you my story. This is a long story but not mine alone. It is also the story of my farmer Damjibhai and his family. If I do not tell my story now, it might be too late!

I was born in Vangaam in Gujarat. That year there was a good bajra (millet) crop. There was a festive mood in the village. Our area was famous for its grain and vegetables.

Each year Damjibhai kept aside some seeds from a good crop. This way
our bajra family went on from one generation to another. Good seeds were stored in dried gourd (lauki ) which was coated with mud.

But that year Damjibhai himself made a strong wooden box to store us. He put in neem leaves to protect us from insects. He put different seeds in different compartments of the box. That was our beautiful home!

In those days Damjibhai and his cousins lived together. It was a large family. Everyone in the village helped each other, even in farming. When
the crop was ready and harvested, everyone celebrated together.

Oh! Those wonderful days! With big feasts and lots to eat! In the winter, it would be time to enjoy the undhiya (a kind of stew). All the vegetables were put into a clay pot, along with fresh spices. The pot was sealed and kept between hot coals. The vegetables cooked slowly in this special cooker, on the fields.

Oh, I forgot, the pot was placed upside down! That is why the dish was called undhiya or “upside down” in Gujarati. Undhiya would be eaten with bajra rotis, freshly cooked on the chulha. Oh, what an earthy delicious flavour!

Along with that, home-made butter, curd and buttermilk was served.
Farmers would grow many different kinds of crops – grains and vegetables according to the season. The farmers kept enough for their needs and sold the rest to shopkeepers from the city.

Some farmers also grew cotton. At home, family members spun cotton on a charkha (spinning wheel) to make cloth.

When times changed:
Over the years, many changes took place in the village. Some places could get water from the canal. They said the canal brought water from far away – where a dam had been built on a big river.

Then electricity came. Switch on the button and there was light! People found that only one or two crops, like wheat and cotton, got better prices in the market.

So most farmers began to grow only these. Soon we – old friends bajra and jowar, and also vegetables – were forgotten and dismissed, even from
Damjibhai’s fields! Farmers even began to buy seeds from the market.

People said they were new kinds of seeds. So farmers did not need to store seeds from the old crop.

Now people in the village cooked and ate together only on very special days. As they ate, they would remember how tasty the food used to be in the past – fresh from the fields.

When the seeds have changed, how could food ever taste the same! Damjibhai was getting old. His son Hasmukh looked after the fields and the family. Hasmukh was making a lot of money from farming. He rebuilt the old house.

He brought new machines for farming. He used an electric motor to pump water. He bought a motorcycle to go to the city easily and also a tractor to plough the field. The tractor could do in a day, what the bullocks would take many days to do.

Hasmukh would say, “Now we are farming wisely. We grow only what we can sell in the market at a good price. With profits from our fields we can improve our life.

We can make progress.” Lying forgotten in the wooden box, I and
the other seeds had our doubts. Is all this really progress? There is no longer any need for seeds like us, and animals like the bullocks. After the tractor has come, even people who worked on the fields, are no longer needed. How will they earn money? What will they live on?

More and more expenses:
The next twenty years saw even more changes. Without cows and buffaloes, there was no cow dung, to be used in the fields as fertilizer. Hasmukh had to buy expensive fertilizer.

The new kinds of seeds were such that the crops were easily affected by harmful insects. Medicines had to be sprayed on the crops to keep away
the insects.

Oh, what a bad smell these had, and how expensive they were! The canal water was not enough for the new crops. All the farmers used pumps to lift
water from deep under the ground.

To meet all these expenses, loans had to be taken from the bank. Whatever little profit was made, was used to repay the loan. But there was little profit!

Everyone was growing cotton, so the cotton prices were not as high as before. The soil itself was no longer the same. Growing the same crop
over and over, and using so many chemicals, had affected the soil so much that now nothing could grow well there.

It was becoming difficult to earn a living by farming alone. Hasmukh too changed with the times. He is often tense and angry most of the time. His educated son Paresh did not want to do farming. He now started work as a truck driver.

After all, the bank loans still had to be repaid. Often Paresh doesn’t come home for days. At times he is away for a week. Two days back when he came home, Paresh started looking for something.

“Ba”, he asked his mother, “Where is Dadaji’s wooden seed box? It will be useful to keep the screws and tools for the truck.” Now do you understand why I told you my story?

Read the report from a newspaper and discuss it:
Tuesday, 18 December 2007, Andhra Pradesh Farmers in Andhra Pradesh have been sent to jail for not being able to pay back their loans.

They had suffered a big loss in farming. One of these farmers, Nallappa Reddy, had taken a bank loan of Rs. 24,000. To repay the loan, he had to take another loan from a private moneylender, at a very high rate of interest.

Even after repaying Rs. 34,000 Reddy could not repay the entire loan. Reddy says, “The bank sends farmers to jail for not paying back small loans. But what about the big businessmen? They take loans of crores of rupees.

Nothing happens to them when they do not return the money!” Nallappa Reddy’s story is shared by thousands of farmers in India who are suffering huge losses.

The situation is so bad that many farmers see no way out of this except to commit suicide. According to government figures 1,50,000 farmers have died like this between 1997 and 2005. This number may be much higher...

Bhaskarbhai’s Farm (Dehri village, Gujarat)
As we entered his farm, we were surprised. There were dead leaves, wild plants, and grass everywhere! Some of the tree branches seemed so dry, as if eaten by insects. At places we saw some plants with colourful leaves.

Why these? Bhaskarbhai said they were croton plants which gave him a signal when the soil became dry. We were surprised! How? He explained that the roots of the croton do not go deep in the ground.

So when the top layer of the soil becomes dry, the croton leaves bend and become limp. This signal tells Bhaskarbhai which part of his farm needs to be watered.

We found the soil soft and crumbly. We could see tall coconut trees, full of fresh coconuts. We thought he must be using some special fertilisers.
Bhaskarbhai said he does not buy fertilisers made in factories.

His soil is fertile because of all the dried leaves which slowly rot and mix with it. He dug the soil a little and told us to look. We saw thousands of earthworms! “These are my soil's best friends”, he said.

The earthworms soften the soil as they keep digging underneath to make tunnels. This way air and water can easily get into the soil. The earthworms also eat the dead leaves and plants, and their droppings fertilise the soil.

Pravin told us about his uncle in the city, who has dug a pit in his garden. He puts dried leaves in the pit, along with all the kitchen waste – peels of vegetables and fruits, and leftover food. He also has earthworms in the pit.

They turn the waste into compost (a natural fertiliser). So his uncle gets good fertiliser without spending extra money. We all had some fresh coconuts from the farm. They were really tasty! We also learnt so much about a new way of farming! Group members : Praful, Hansa, Krutika, Chakki, Praveen, Class–5C

Journey of a bajra seed–from a field to a plate
What can you see in each picture on the next page?
In picture 2 you can see the bajra cobs in the mortar (okhli, usedfor crushing). The cobs are crushed with a pestle (moosli ) andthe seeds are separated from the cob.

You can see the separatedseeds in picture 3. Now this work is also done by big machines,like threshers. We call both these as different ‘technologies’ –using our hands or big machines – to crush the seeds.

Jatryabhai
Jatryabhai was sitting at the door with his daughter Jhimli. They were waiting for Sidya. It was almost night but Sidya had not come home. Two years back Jatrya’s family came to Mumbai from Sinduri village.

Here, they only knew the family of a distant relative. With their help, Jatryabhai began to repair torn fishing nets. But the money he got
was not enough.

They had to pay for the medicines, food, school fees and rent for the house. Here, they even had to buy water. Young Sidya also had to work in the nearby fish factory to earn some money.

From four o’clock till seven o’clock in the morning, he cleaned and sorted the big and small fish. Then he would come home, take a nap, and go to school in the afternoon. In the evening he would wander around the vegetable market.

He would help some memsahib (lady) to carry her bags, or go to the railway station to pick up empty bottles and newspapers to sell to the kabadiwalla (junk seller).

Somehow they were managing their life in the city. It was night, but Sidya had not come home. Jhimli was watching a dance on TV, through the neighbour’s window.

But Jatrya did not like watching TV. Here, everything was so different. The day would pass running around for work, but the evening brought back old memories.



Thinking of old days:
Jatrya was born in Khedi village, in the middle of thick green jungles and hills. His people had been living here for many years even before his grandfather was born.

There was peace in Jatrya’s village, but not silence. There were so many soothing sounds – the gurgle of the flowing river, the murmur of trees and the chirping of birds. People did farming.

They would go to the nearby forest, chatting and singing together, to collect wild fruits, roots and dried wood. While working with elders, children also learnt many things – to dance together, to play flute and dhol, to make pots of clay and bamboo, to recognise birds and imitate their sounds, etc.

People collected things from the forest for their use. Some of those they would sell in the town across the river. With that money they would buy salt, oil and some clothes.

It was a village, but people here lived together like a big family. Jatrya’s sister was married in the same village. People helped each other, in good and bad times. The elders would arrange weddings, and settle quarrels.

Jatrya was now a strong young man. He worked hard in the fields and caught fish from the big river. He and his friends would go to the forest to collect fruits, roots and plants for medicines, and fish from the river, to sell these in the town.

During festival time, Jatrya would dance and play the drum, with boys and girls of his age.

Across the river:
One day the people of Khedi heard that a big dam was to be built on the river. For this, a big wall would be built to stop the flow of the river. Khedi and many nearby villages in that area would be drowned under water.  The people would have to leave their villages and their lands, on which their forefathers had lived for centuries.

After a few days, government officials along with the police started visiting these villages. Small children of the village saw the police for the first time. Some children would run after them, and some would get scared and start crying.

The officials measured the width and length of the river, the fields, forests and houses. They called meetings with the elders of the village.  They said, “Villages on the bank of the river would have to be removed. People having land at Khedi will be given land far away, on the other side of the river.

They will have everything there – a school, electricity, hospitals, buses, trains, etc. They will have all that they could not even dream of here in Khedi.”

Jatrya’s parents and most elders were not happy about leaving
their village. Listening to all this, Jatrya would get a little scared, but also feel excited. He would think that after getting married, he would take his bride to the new house in the new village.

A house where he could just press a button for the light and turn on the tap for water. He could go by bus to see the city. When he would have children, he could send them to school. They will not be like him, who had never been to school.

A new place:
It was a summer afternoon. Jatrya was feeling faint in the hot sun and wind. His feet were burning on the coal tar of the pucca road. There wasn’t a single tree to offer some shade.

Just a few houses and shops. Jatrya was on his way home after buying
medicines. He had an old tyre on his back. These days, he had to light his stove with just these rubber pieces of old tyres.

These caught fire fast, and also saved some firewood. But the smoke and smell of burning tyres were terrible! In this new Sinduri village, they had to pay money for everything— medicines, food, vegetables, firewood, and fodder for the animals.

They could just not afford to buy kerosene. But from where to get the money for all this? Thinking of all this, Jatrya reached home. The roof made of a tin sheet made the house hot like an oven.

Jatrya’s wife had high fever. His daughter Jhimli was rocking her little brother Sidya to sleep in her lap. After all, there was no other older person with them.

Jatrya’s parents had been so sad about leaving Khedi that they had died before he moved here.

In Sinduri there were only eight-ten families he could call his own, those from his old village. The whole village had got scattered and people had gone wherever they had been given land.

This was not like the new village Jatrya had dreamt about. There was electricity, but only for sometime in a day. And then, the electricity bill had also to be paid. There were taps, but no water!

In this village, Jatrya got just one room in a tin shed. It had no place to keep the animals. He also got a small piece of land. But that was not good for farming. It was full of rocks and stones.

Still Jatrya and his family worked very hard. But they could not grow much on the field, and could not make enough money even to buy seeds and fertilisers. In Khedi, people did not fall sick often.

If someone fell ill there were many people who knew how to treat them with medicines made from plants. People felt better after taking those medicines. Here in Sinduri, there was a hospital but it was difficult to find doctors, and there were no medicines.

There was a school here, but the teacher did not care much about the children from Khedi village. These children found it difficult to study in a new language.

The people of Sinduri did not welcome the newcomers from Khedi. They found their language and way of living strange. They made fun of the Khedi people by calling them ‘unwanted guests’. Not much of what he had dreamt had come true!

Some years later:
Jatrya stayed for a few years in Sinduri. The children were also getting older. But Jatrya’s heart was not here in Sinduri. He still missed his old Khedi.

But there was no Khedi now. There was a big dam and a big lake of collected water in and around Khedi. Jatrya thought, “If we are to be called ‘unwanted guests’, then at least let us go to some place where our dreams can come true.”

Jatrya sold his land and his animals and came to Mumbai. Here, he started a new life with his family. His only dream was to send his children to school, to give them a better future, a better life.

Here too, things were not easy. But he hoped that things would get
better. Jatrya started saving money to repair his one-room shack. His
relatives would tell him, “Don’t waste money on this. Who knows, we may have to move from here too. In Mumbai there is no place to stay for
outsiders like us.”

Jatrya was scared and worried. He thought, “We left Khedi for Sinduri, we then left Sinduri for Mumbai. If we have to move from here too, then where can we go? In this big city, is there not even a small place for my family to stay?”

WHO WILL DO THIS WORK -TEXT

WHO WILL DO THIS WORK
ENVIRONMENTAL STUDIES
CBSE-V

Have you seen such scenes around you? Have you ever thought of people who do this work? Can you imagine how they would feel?
Why do you think people need to do this kind of work?

Our friends spoke to some staff who do cleaning jobs. Here are some of the things they told us.
Since when have you been doing this work?
A. About twenty years. Since I completed my studies.
Q. Why did you not study further? You could have got some other job?
A. You need money for studies. And even after that most of our people continue to do this kind of work.
Q. What do you mean?
A. Since our great grandfathers’ times... or even before that, most people of our community have been doing this work. Even after getting a college degree, our people do not get any other kind of job. So they have to do this work.
Q. Why is that so?
A. That is the way it is. In the entire city, all the people who do this kind of work are from our community. It has always been so.
Interview (adapted) from the documentary film ‘India Untouched’ by Stalin. K.

Imagine
What would happen if nobody did this work? If nobody cleared the garbage lying outside your school or your house for one week, then what would happen?

Think of some ways (machines, or other things) so that people would not have to do the work they don't like to do. Draw a picture of what you thought. (These pictures are also made by children)
Do you think that anyone has ever tried to change this situation? Yes, many people have tried. People are trying even today. But it is not easy to change this.

One such person was Mahatma Gandhi. Gandhiji had a friend Mahadevbhai Desai. Mahadevbhai’s son Narayan also stayed with Gandhiji when he was young. This incident is from Narayan's book.

Teacher’s Note
Remembering those days
When Narayan (Babla) was about 11 years old, he was staying in Gandhiji’s Sabarmati Ashram. Like everyone else in the Ashram, he had to do various kinds of work. One of his jobs was to teach the guests how to clean the toilets.

In those days, the toilets were not what we know today. There used to be holes under which baskets were kept. People sat on the holes. Later the baskets had to be lifted by hand, to be emptied.

It was the usual practice that people from a particular community would do this work. But in Gandhiji’s Ashram, every person had to carry the basket to the compost pit and empty it there. No one was excused from this task - not even the guests. Narayanbhai remembers how some people used to try and avoid this work. Some even left the Ashram because of this.

Some years later Gandhiji went to stay at a village, near Wardha in Maharashtra. Gandhiji, Mahadevbhai and others started to clean the toilets in the village. They did this for some months. One morning a man coming from the toilet, saw Mahadevbhai.

He pointed to him and said “There is a lot of dirt over there. Go and clean that!” When Babla saw this, he was very angry. He thought, the villagers felt that this was not their work. This was for Gandhiji and his team to do. He asked Gandhiji why this was so. Gandhiji replied, “Untouchability is a serious matter.

Lot of hardwork will be required to change this.” Narayan knew that the people who usually did this work were thought to be untouchable. He asked “What is the use if the village people do not
change their thinking? They have become used to someone else doing this work for them.”

Gandhiji replied, “Why”? Don’t you think the people who clean also benefit from it. They also learn a lesson. To learn something is like learning a new skill. Even if it is a cleaning job.”

Little Narayan was not convinced. He again argued, “Those who make a place dirty but do not clean it should also learn lessons.” Gandhiji and Narayan continued to argue about this. But when he grew up Narayan always followed the path shown by Gandhiji. From the book in Gujarati by Narayanbhai Desai – Sant-Charan-Raj, Sevita, Sahaj

A childhood story
This story is almost a hundred years old. Seven-year old Bhim went to Goregaon
in Maharashtra with his father to spend his holidays. He saw a barber cutting the long hair of a rich farmer’s buffallo.

He thought of his own long hair. He went to the barber and asked for a hair cut. The barber replied, “If I cut your hair both my razor and I will get dirty.” Oh, so to cut human hair can be dirtier than cutting an animal’s hair, wondered little Bhim.

Later this little Bhim was known as Bhim Rao Baba Saheb Ambedkar.
He became very famous across the world. Baba Saheb fought for justice for people like him. After India’s freedom the Constitution was prepared under the leadership of Baba Saheb.

Narayan and Gandhiji discussed all this many years ago. Have
things changed now? A conversation in school - the reality today
Hetal : I am Hetal, and this is Meena. We both study in Class III.
Q: What all do you do in school.
Meena: We clean the ground
Q: Do all children clean
Hetal : No, not all.
Meena : We also have to clean the toilets. We do it on different days. I
clean on Monday, she does on Tuesday, and she on Wednesday … All
the children from our community do this.
Hetal : We have to carry twenty buckets of water for this. We have to
sweep and wash.
Q : Why only you? Why not all the children?
Hetal : Only we have to. If we don’t we get beaten.

DIFFUSION-TEXT




UPTAKE OF WATER AND SALT BY PLANTS
BIOLOGY

You have learnt earlier that plants survive if water, minerals ans others nutrients are provided to them. In this lesson, we will learn how these substances enter the plant cell. To understand this we have to understand the terms diffusion and ‘osmosis’ and the processes associated with them.

Diffusion
We will do a simple experiment to understand the process of diffusion. Take a beaker full of water and carefully add two or three crystals of copper sulphate or potassium permanganate.
When the crystals settle down on the bottom of beaker, leave it on the table and do not distrub this and Watch it from time to time and record the changes in the colour of water.
The crystals starts dissolving in water. The water around the crystals will appear dark in colour. As time progress, all the wter in the beaker becomes coloured- initially pale in colour and slowly all the water in the beaker becomes uniformly coloured.
Let us now understand the changes that have taken place.
When the permanganate crystal settles at the bottom of the beaker, a small amount of water comes in contact with the surface of crystal. This water dissolves permanganate and results in the formation of a 
concentrated solution of the salt at the point. 
This is the reason for the appearance of small dark coloured spot at the bottom of the beaker in the intial stages.
From this spot, the molecules of permanganate move away and get dispered all over the water in the beaker. As this goes on, rest of the water becomes coloured.
As the concentration of dissolved permanganate increase, the colour of water also becomes darker. Finally, after along time, all the molecules of permanganate are uniformly distrusted in the water and water in the beaker becomes uniformly coloured.
From this experiment we cleared that:
1. All the molecules in a solution are in a state of       continuous motion.
2. They move randomly in all the directions.
3. Molecules move from higher concentration to         lower concentration.
4. this movement from higher to lower                  

    concentration occurs till the concentration    
    becomes equal at both the points..


The process of movement of molecules or ions from appoint of high concentration to a point of low concentration till the concentration at both the points become equal is called diffusion.
We have not supplied and additional energy for the movement of the molecules. The energy required for the movement of molecules comes from the kinetic energy of the molecules its self. The process of diffusion occurs nor only in water but also in air.
The process of diffusion occurs not only in water but also in air. This is commonly amounts in the bottle is opened- molecules responsible for perfume are in the air amounts in the bottle while there are no perfume molecules in the air surrounding the bottle. Hence , perfume molecules diffuse through air to all the areas in the room.
Diffusion is physical process and no external energy is required for the movement of molecule by diffusion.
