Science is better understood by observation and more so when children can relate their own surroundings and environment to what they read in their textbooks. The science textbook for the 5th class is ready and I have gone through it. The book is simply written, clear, comprehensive, interesting, and most of all it is Ladakh- appropriate. Each chapter has been developed as a self-contained unit of study that may be used in any sequence the instructor wishes. Numerous illustrations have been introduced wherever necessary. This I feel will make students thoughtful viewers; at the same time it teaches them to be thoughtful readers. The team of dedicated teachers from Education Department LAHDC, Leh and SECMOL have developed this book in collaboration with the Jammu and Kashmir State Board of School Education. The Ladakh Autonomous Hill Development Council, Leh has actively supported it from the very beginning. I am sure this book will find an encouraging response from the children, parents, and teachers. I would like to thank the teachers, SECMOL, J&K Board and all other people involved in the development of this book. Rigzin Spalbar Chairman/CEC Notes for the Teacher Chapter 10: Air and Air Pollution Why this chapter? Air surrounds us and is essential for life on earth. It cannot be seen, but children are made aware of its presence and properties in this chapter, through various simple experiments. A brief recapitulation of the uses of air is included. The phenomenon of air pressure is dealt with in relation to altitude and the low air pressure in Ladakh. This dispels a common belief that the symptoms caused by low oxygen at high altitudes is a result of herbs that grow there. The second section deals with some causes of air pollution and some ways to reduce it. It deals with the situation in Ladakh, particularly in the towns. Global warming is also a form of air pollution. It is mainly caused by burning any kind of fuel. Scientists report that the glaciers in the mountains all over the world are already decreasing in size due to global warming, which may result in serious water shortages. Scientists also say that global warming may make storms and droughts unpredictably worse in different places. The smoke and the gases emitted from any kind of combustion, for example in vehicles, factories, etc. goes up and accumulates in the atmosphere. This layer of carbon dioxide acts like the polythene of a green house and allows incoming radiation from the sun but does not allow the resulting heat to escape from the Earth. This leads to the rise in temperature called global warming. If we reduce the burning of fuel to heat our houses and instead use greenhouses for heat, it can help reduce global warming! So greenhouses help us against the greenhouse effect. If possible, invite a guest speaker knowledgable about environmental issues, who could come and talk to students about the pollution problems specific to Ladakh. Often children are enthusiastic to start a cleanup campaign, and this should be encouraged. Points for Discussion/ Clarification The section on air is largely activity-based so that the children have opportunities to explore everyday phenomenon related to air. Hence, it is important that every experiment be carried out in class. After doing an experiment or demonstration, encourage children to share their observations and give reasons for what they see. This develops their observation and analytical skills. This chapter is only an introduction to the ways in which human activities negatively affect the atmosphere. You can encourage discussion on the lifestyle changes that are taking place in Ladakh due to various reasons, and their influence on the environment. Materials Needed For the activities you will need: - a pan of water - a bottle with a narrow neck - some thin paper - a lump of soil from the fields - a glass - balloons. Chapter 10 Air and air pollution It’s everywhere and all around, It’s inside us and underground. Sometimes you can hear it, Sometimes you can feel it, And sometimes you can see it move things about. Yet you can never hold it or see it. You cannot live without it. What is it? Air! Air is all around us. It is everywhere. Since air has no colour or smell, many things may look “empty” or seem to have nothing in them. Let’s see if “empty” things are really empty, or whether they contain something. A) You will need a pan of water and a clear plastic bottle. Step 1: Fill the pan with water. Push the bottle, mouth down, into the pan of water. What do you find? Step 2: Now tilt the bottle a little. What happens? Was the bottle really empty? Step 3: Push . the bottle down into the water and then squeeze it. What happens? Step 4: Push some dry paper into the bottom of a glass, so it won’t fall out. Turn the glass upside-down and push it straight down under the water. Don’t let it tilt! Then pull it straight up out of the water. Is the paper wet or not? B) Take a lump of soil from a field and put it into a glass of water. What comes out of the soil? What does this show? In experiment A, step 1, air prevented water from entering the bottle. In step 2, when you tilted the bottle some air escaped as bubbles and a little water entered the bottle. In step 3 air was pushed out of the bottle when it was squeezed. When the bottle returned to its original shape after the squeezing stopped, water entered the bottle to replace the air that was squeezed out. In step 4, air filled the glass so water could not enter. Experiment B shows that air is even found in the spaces in the soil. The above experiments show that air is everywhere around us. Air is a mixture of gases including oxygen, carbon dioxide, nitrogen, etc. The largest portion of air is nitrogen. Air also contains water vapour, dust particles and pollutants. This bunch of balloons shows the proportions of the different gases in the atmosphere: blue balloons are nitrogen, the red ones are oxygen, and the single white balloon is for all the other gases. All animals need oxygen to breathe. During the process of respiration, they give out carbon dioxide. During photosynthesis green plants use carbon dioxide and give out oxygen. In this way the amount of oxygen and carbon dioxide in the atmosphere is maintained. Did you know that even fire needs oxygen? When anything burns, oxygen is used and carbon dioxide is given out. Properties of air Atmosphere Earth We have lear ned earlier that air occupies space. Now, let’s learn about another property of air. Air exerts pressure Air covers the earth like a blanket. It extends above the earth’s surface for many kilometers. This layer of air is called the atmosphere. Air and Air Pollution All this air presses down on the earth’s surface. In general air pressure is most at sea level. This is called the atmospheric pressure at sea level. The reason air has pressure is because air has weight. This diagram shows how as we go upwards from sea level, the air is thinner. Down at sea level the air is pressed together so there is more of all the gasses in a given volume of air at sea level than at high altitude. Air becomes thinner Sea level Air pressure at high places Places that are high in the mountains h a v e t h i n n e r a i r. This means that there is less gas, including oxygen, in the same volume of air. People who live in high places get used to this. Changes happen in our lungs and blood so that our bodies can get enough oxygen. But when people from lower Thin air More air places like Delhi and Jammu travel to high places they may feel giddy, breathless, or get a headache for the first few days. This is because there is suddenly thinner air and less oxygen. They should rest for one or two days till their bodies get used to breathing thinner air. A few people can even get seriously ill at high altitude. If you have travelled to very high places like Khardong-la, you may have felt such problems. This is because Khardong-la is 18,380 feet above sea level, much higher than Leh at 11,500 and Kargil at 8,750 feet above sea level. If you feel these symptoms, you should rest. But if the symptoms become worse, you should move to a lower altitude immediately. People who climb very high mountains like Mt. Everest (29,028 feet) usually carry cylinders of oxygen. At such great heights there is very little oxygen to breathe. Air pollution You have learned about water and land pollution. What is pollution? Pollution is any change in our environment that harms living things. Human activities are the major cause of pollution. When we burn fuels such as wood, petrol, diesel, cow dung, coal, or rubbish, especially plastic, many substances including gases, smoke and tiny bits of dust get into the air. Some of these things can’t be seen. However they are harmful to living and some non-living things. In humans, polluted air can irritate eyes and cause headaches, tiredness, breathing problems, serious lung disease and cancer. When any fuels is burnt, carbon dioxide is produced. The amount of carbon dioxide in the atmosphere has increased in the last 100 years and is causing the earth to get warmer. This is called global warming. It is causing changes in the weather in different parts of the world. For Ladakh the most dangerous effect may be that the glaciers are becoming smaller. Because global warming may cause so many problems in the world, people are trying to find ways to reduce the use of fuel. Can you find five ways that air is being polluted in the picture below? Air and Air Pollution Oil rig Fossil Fuels Fossil fuels are formed from the remains of plants and animals that have been buried under the ground or the sea for lakhs of years. Examples of fossil fuels are coal, petroleum oil, and natural gas. You may have seen coal being used in bokharis. We get kerosene, petrol, and diesel from petroleum oil. Sea Digging coal from under the ground Oil Do you know how we use fossil fuels? Find out and fill the chart below. For each fossil fuel fill in as many uses as you can find out. Fossil fuel How we use it Coal Kerosene Diesel Petrol Natural Gas As you can see, we use a lot of fossil fuels in our daily lives. These pollute the air and add to global warming. Therefore we have to find ways to reduce the use of fossil fuels. How to reduce air pollution The best way to reduce air pollution is to use other sources of energy that do not pollute as much as fossil fuels. We can also reduce the use of fossil fuels by following some simple methods in our daily activities. Other sources of energy There are other sources of energy that do not pollute as much as fossil fuels do. These are the sun, water, and wind. Sun When we warm ourselves in the sun, we use the sun’s energy, which is called solar energy. This energy can be used for cooking, heating, and electricity. Solar panels change the energy of sunlight into electricity. Ladakh is a good place for solar energy because it’s a desert so most days are sunny and it’s high altitude so the air is thin and clear. Look at some of the uses of solar energy. Solar lamp Solar cooker South facing solar-heated house Water Flowing water has energy which can be used. A water mill uses the energy of flowing water to turn a heavy-stone to grind grain. In many places in Ladakh prayer wheels are even turned by stream water. Water mill Air and Air Pollution We can also generate electricity from flowing water. This does not pollute the air. It is called hydroelectricity. The biggest hydel projects in Ladakh are at Stakna and Kargil town. Do you know any hydel-project in your area? Wind People can also get energy from the wind where Wind-powered electricity it is strong and blows continuously. In Ladakh wind power is not used much because the wind does not blow continuously and the air is thin here at high altitude. Ways to reduce the use of fossil fuels Look at the list of uses of fossil fuels that you made in the previous activity. Group them into the four categories given below. The best way to reduce air pollution is to reduce the use of fuels. A few suggestions on how we can do this in the four categories are given below. FUEL COOKING HEATING TRANSPORT Kerosene Coal Diesel Petrol Natural Gas Cooking 1) If we cover cooking pots with a lid, the food cooks faster. This is because it does not allow the steam to escape. A pressure cooker also reduces fuel by cooking food faster. 2) Before cooking pulses, soak them in water overnight. This makes them cook faster. ELECTRICITY Heating As you learnt in class 4, the best way to reduce the use of fuel for heating in the winter is to make buildings that remain warm in winter. Can you remember? What are the main points in making a house warmer without burning fuel? Transport Which do you think pollutes more: forty people travelling together in one bus or forty people driving forty separate cars? That’s why people who want to reduce pollution take the bus, use bicycles, or walk. Electricity Do you ever see electricity being wasted? Switch off lights, TV, radio, and other machines when not in use. Did you know that it takes much more electricity to make heat than light? So the old style light-bulbs, which get very hot, use much more energy than CFL bulbs, which A CFL bulb saves energy don’t get so hot. Leh Hill Council has decided that only CFL bulbs should be used, so that there will be enough electricity for everyone. EXERCISES I Answer the following questions: 1.

Blow up the balloon, hold it high in the air, then let it go. What happens? When the compressed air inside the balloon rushes out, it pushes the balloon in the opposite direction. This principle is used in jet planes.

You know that each Panchayat acts like a government for a small group of villages. But to take care of the whole district, we have a government called the Hill Council. Leh and Kargil Districts each has its own Hill Council. Each district is divided into 26 Hill Council constituencies with a few villages in each. The people of each constituency elect a Councillor. The Councillors from all the constituencies form the Hill Council of the district. Which constituency do you belong to? How many villages do you have in your constituency? Electing a Hill Councillor Electing the Hill Council CEC The Hill Council Who can become a Hill Councillor? Not everybody can. For example, people with government jobs cannot become Councillors. People who are more than 18 years old can vote in elections. They vote for the person they think will be the best councillor for their constituency. The person who gets the most votes becomes the Councillor for that constituency. Elections are held in the district every five years, so when a person is elected, he or she will be Councillor for five years. Who is the Hill Councillor for your constituency? People of the district When was the last Hill Council election held? When do you think the next election will be? The Executive Council The first time the Hill Councillors meet after the elections, they elect a chair man from among themselves. The Chairman is the head of the Hill Council. The Chairman is also called the Chief Executive Councillor (CEC). The CEC chooses four members from among the 26 councillors as Executive Councillors. At least one Executive Councillor should belong to the main minority community in the region. Who is the CEC of your district? The work of the Hill Council The Hill Council makes many regulations and decisions to develop the district. They make their decisions by voting among themselves. Decisions are made when more than half the councillors agree. The Hill Council is in charge of many things like schools and education, government hospitals, roads, irrigation, etc. Why do we have a Hill Council? Most districts in India don’t have Hill Councils. Although Ladakh is a part of Jammu and Kashmir, there are many things in Ladakh that are different from other parts of the state. For example, Ladakh is a high desert region, and the rest of J&K is not. For these reasons, the people of Ladakh felt that they would be able to understand and solve their own problems best. So the Government of India formed separate Hill Councils for Leh and Kargil districts. Other government bodies in India State Government We are in the state of Jammu and Kashmir. Our state, like all others in India, has its own state government. The people of the state elect the state government, just as the people of the district elect the Hill Council. Each state is also divided into constituencies, which are bigger than the constituencies of the Hill Council. From each constituency, people elect a Member of the Legislative Assembly (MLA). The MLAs from all over the state form the Legislative Assembly and elect a Chief Minister. The Legislative Assembly meets in the state’s capital city and makes laws for the whole state. Jammu and Kashmir is the only state in India that has two capitals—Jammu in winter and Srinagar in summer. Who is the Chief Minister of Jammu and Kashmir? Who is the MLA for your constituency? Central Government The Central Government rules India. When there are elections for the Central Government, people all over the country vote for an MP (Member of Parliament) from their constituency. Leh and Kargil together form one MP constituency, so Ladakh has one MP. MPs from all over the country come together in Delhi to form the Parliament of India, and make laws for the whole country. The MPs elect the Prime Minister of India. Do you know who the Prime Minister of India is? Who is the MP from Ladakh? Governing Ourselves Exercises I Answer the following questions 1. Why were Hill Councils formed in Ladakh? 2. How are Hill Councillors elected? 3. Mention three duties of the Hill Council 4. How are Prime Ministers and Chief Ministers elected? II True or false? If false, give the correct statement. 1. All districts of India have Hill Councils. 2. The Chairman of the Hill Council is also called the Chief Executive Councillor. 3. There are 100 Hill Council constituencies in Ladakh. 4. The Hill Councils looks after the whole country. 5. The Hill Councils looks after schools in the District. Things to do 1. Find out what village projects your Hill Council has started. 2. Discuss what you think the Hill Council can do for your village to make it better. 3. Look at the picture on page 66, and then in the pictures below fill in the blanks for what each group of people stands for.

Chapter 9 SOME HISTORICAL MONUMENTS OF LADAKH Rinchen had a dream one night in which a fairy came to her and said, “I have written some clues about a few historical monuments of Ladakh and hidden them in different places. If you find the clues and solve them, you will get a secret gift. Here is the first clue:” “Once a capital before Leh: a gonpa in a palace below the walls of a fort.” Rinchen got up with a strange feeling and told her brother Norgay about her dream. The children did not understand and were confused. Suddenly a tiny old man with a long cap and a short stick appeared. He said, “I’m Zbalu. I will help you find your secret gift. Let’s go!” The children took his hands and flew up in the sky with him. Shey Palace Soon they reached Shey near the Indus River. At Shey, they saw five big figures of the Buddha carved on a rock. “These were carved before the palaces were built,” explained Zbalu. They flew up the hill. “Almost 1000 years ago, Ladakhi kings came to live here. From their fort high on the hill, they could see a wide area,” explained Zbalu. “They could see enemies coming from far away. Maybe that’s why they chose this place for their capital.” “There’s nothing left of the older fort now except the broken walls!” exclaimed Rinchen. Zbalu explained, “Oh! that is because the old fort was built a long time ago, during the times of Lhachen Spalgon. He is one of the earliest kings of Ladakh. In those days his palace was considered one of the best. Sadly, over the years it was destroyed. Then in the 1600s, King Deldan Namgyal built this big palace here. The gonpa outside the palace is three storeys high and has a statue of Buddha so big that you have to climb upstairs to see the head!” Shey Palace with the ruins of the old fort in the background Historical Monuments “Oh! So these buildings at Shey were built by different kings.” said Norgay. The children looked around for their next clue. Norgay found a piece of paper sticking out of a hole in the wall. He read out the next clue. “Beside the Indus river, and not high on a mountain. Remember Rinchen Zangpo.” “It could be Alchi!” exclaimed Rinchen. “My father said this was one of the few gonpas not built on the top of a mountain.” “Good! Let’s go,” said Zbalu, and they flew along the Indus River. Alchi Gonpa Soon they reached Alchi. Rinchen said “This looks different from other gonpas I’ve seen.” Zbalu explained,“Yes it was founded around 1000 years ago. The King of Tibet wanted to revive Buddhism there so he sent scholars to Kashmir. In those days most people of Kashmir were Buddhist. One of the scholars who went to Kashmir was Lotsawa Rinchen Zangpo. Afterwards he built most of this gonpa. He brought artists from Kashmir to decorate it.” Rinchen and Norgay stopped to look at the Buddha, lions, other animals and plants carved on the wooden entrance and pillars. The children stood in astonished silence. “This is so beautiful!” Norgay said. When they went to another building, they found three statues of Buddha standing inside, taller than the first floor. Zbalu showed them the historical pictures painted on the clothing of the statues. Norgay was looking at the walls. “The style of building and painting here is different, isn’t it?” “Yes,” said Zbalu, “That’s because the Kashmiri Buddhist style was different from the Tibetan Buddhist style that you see in most other gonpas.” Norgay stepped closer and put his hand out to touch the painting. Zbalu quickly reacted, “Don’t touch the paintings! They are very old, and touching them will only wear the paint away. Then these beautiful paintings would be spoiled forever! You wouldn’t want that to happen now, would you?” asked Zbalu. “No! I’m sorry. I didn’t mean to harm the painting,” said Norgay. “It’s alright, child. It’s important that you have realised your mistake. I wish all the other visitors understood too!” As they were walking under one of the chortens outside, Rinchen found the next clue. “By the side of the Leh to Srinagar road, he stands tall and alone.” The children said, “It must be the statue at Mulbekh in Kargil district.” Zoom! They set off and reached Mulbekh. Mulbekh Statue They landed near a big statue of the Buddha carved on a huge rock. Zbalu told them, “This statue was probably carved more than 2000 years ago! In those days, there were not many Buddhists in Ladakh, but Kashmir and most of India was Buddhist. People say the Indian King Kanishka sent monks to teach people here about Buddhism. They carved this statue.” “It’s so huge!” Is this the Mulbekh Chamba? cried Rinchen. “Yes. People call it the Mulbekh Chamba because of its size. But scholars now believe it is a statue of Chenrezig Avalokiteshwara, the Buddha of Compassion.” explained Zbalu. “This is probably the oldest existing statue of the Buddha made in Ladakh.” As the children looked around them, they found their fourth clue near the feet of the statue. “Pilgrimage place near Kargil, deep in a valley” “That sounds like the tomb of Sayeed Mir Hashim in Karpo Khar. Come along, we have to fly to the Suru valley to get there.” Historical Monuments Tomb of Mir Hashim “Uncle Zbalu, who was Mir Hashim?” Norgay asked as they flew over the mountains. “Oh, Sayeed Mir Hashim is a very famous man from Kashmir! About 300 years ago Queen Thi La Khatun of Purig invited him to give religious education to her son, Thi Mohammad Sultan. He The tomb of Sayeed Mir Hashim was very important to the spread of Islam in Purig.” They soon reached the village of Karpo Khar. “It looks like an old house! Where is the tomb?” Rinchen asked. “His tomb is inside. Do you know how many people visit this site? Not just Muslims, but also Buddhists and Hindus visit this place. Many people believe that if you visit Mir Hashim’s tomb your wishes will come true.” Norgay wanted to make a wish, but Rinchen was eager to find the next clue. The children were hunting for their next clue, when suddenly Norgay stumbled upon a big box full of beautiful and colourful toys hidden behind a rock. “Oh, good! We have found the secret gift!” cried Rinchen happily. “Thank you Uncle Zbalu for helping us and for showing us all these wonderful places with their interesting histories.” Zbalu only laughed. “No problem. Now let’s go home,” and off they flew once again over the mountains. Exercises I Answer the following: 1. Are there other palaces in Ladakh other than Shey Palace? If there are, name some of them. 2. Who invited Sayeed Mir Hashim to Ladakh and why? 3. Who visits Sayeed Mir Hashim’s tomb? 4. What is probably the oldest existing statue in Ladakh? 5.

Sengge Namgyal/Deldan Namgyal/Thi Namgyal built the palace at Shey. 2. Rinchen Zangpo was sent to India by the King of India/the King of Western Tibet/the King of Purig. 3. Sayeed Hashim/Rinchen Zangpo/the Prophet Mohammed came to Ladakh to spread Islam. IV Match the place with its age and write complete sentences. 1. Deldan Namgyal’s Shey Palace 2. Mulbekh Chamba more than 2000 years old. about 400 years old. 3. Mir Hashim’s tomb about 1000 years old. 4. Alchi gonpa around 300 years old. Historical Monuments Things to do Your village or nearby area might have an old structure — a fort, monument, gonpa, mosque, palace, or an old house that has an interesting past. Visit these places as a class trip. These places are an important way to learn about history. Many places in Ladakh have stones carved hundreds or thousands of years ago. These have pictures and writing on them, and we can still discover new information about history from them. Find out the history of a gonpa or mosque you have visited. Your history must have the following information: when it was built, who built it, and why. Are there any statues there, and whose? Is there a festival celebrated there? Are there important visitors or special features? Are monuments and other historical things in your area being damaged over time? Discuss in class, and think of ways in which you and your village can help protect and preserve these places. VOCABULARY [}]-Ø*]!

Box 4 Leh, Ladakh 194 101 India Foreword From the beginning children are curious about the people, animals, plants and materials around them. They learn about their environment through their own first-hand experiences, from their parents, through the media and from a variety of other sources. Schools have a definite role in helping their pupils make sense of these experiences and in developing their knowledge and understanding of the physical and human processes which interact to shape the environment. This is why Environmental Education is one of the most important areas and a compulsory part of our school curriculum. This subject should generate and promote among learners: • A scientific mindset characterised by the spirit of enquiry and problem-solving; • An understanding of the environment in its totality, both natural and social, and its interactive processes, the environmental problems and the ways and means to preserve the environment; and • An understanding of the diversity in lands and people living in different parts of the State’s composite cultural heritage. This textbook of Environmental Studies part 1 (Science) has been developed to realise these objectives. It has been prepared by SECMOL for Class V children of Ladakh and is based on the physical and social environment that surrounds them. The efforts of SECMOL in preparing the book are laudable. It is hoped that the book will help us to develop among children awareness of the environment and build on and reinforce their curiosity about the natural and man-made environment. Awareness and curiosity take different forms like recognition of beauty in a stretch of countryside, the appreciation of animals and the relationships and balance among them, etc. The essential element common to all this is the desire to understand why things are as they are and what is needed to maintain or, where necessary, to change them. The Board is indeed happy to produce this book for Operation New Hope for children of Ladakh region. I take this opportunity to appreciate the efforts of Sh. Sonam Wangchuk and his team of dedicated colleagues at SECMOL, Leh for preparing this book. I also place on record my profound appreciation of Mr B.A. Dar Director Academic of the Board for his contribution in editing the book. Efforts of the staff of Academic Division (Curriculum Development and Research Wing and Academic Section) in getting the book processed are equally recognised and appreciated. Prof. J.P. Singh (Chairman, J&K Board) Section 1 Our Bodies and Health Hints for the Teacher Why this section This unit includes the chapters Food for Health, Internal Organs and the Skeletal System, What Happens to the Food We Eat, and Sources of Water. It is important for children to know their bodies, the various organs, and their functions. This will enable them to take care of their bodies and themselves. To stay healthy, children should be aware of the relationship between their health and the food and water they take. “Food for Health” discusses different kinds of food and their importance in a person’s daily diet. It introduces the concept of a balanced diet, and also stresses the need for adequate safe drinking water. The chapter on “Internal Organs and the Skeletal System” is divided into two parts. The first part introduces some of the vital organs in our body. It gives children the opportunity to voice their existing knowledge about some of these organs, and then builds on that knowledge. We expect children to develop a familiarity with various internal organs before the details of their functions are taken up in following chapters and future classes. The section on the Skeletal System uses the human body as a live working model to describe its functions. Try to make each child do all the simple activities given in the chapter. By the end of the chapter children should have an impression of how all the bones in our body work together as a functional system. “What Happens to the Food We Eat” describes the main organs of the digestive system, and how they work. Some simple experiments have been included to make children understand the processes taking place during digestion of food. Moving one step ahead from the previous chapter, this one deals with some processes taking place in our internal organs, in addition to their functions. Keeping in mind the grade level, some organs like liver, pancreas, etc. with complex functions have not been included. “Sources of Water” familiarises children with different sources of water we use and the causes and prevention of water pollution. Materials Needed Food for Health Snakes and Ladders game: dice, some counters. What Happens to the Food We Eat Food-pipe activity: One-foot-long flexible pipe, some left over food. Stomach activity: Plastic bag, left-over food. Absorption of Food: A shirt or kameez sleeve, small stones or pebbles. Points For Discussion/Clarification Food For health Sprouted peas and dal are a good source of fresh vitamins in winter. To make a sprout salad in class, soak a few peas in warm water 2 to 3 days before the class so that you have the sprouts ready for the class. What Happens to the Food We Eat The incident with Dr. Beaumont and the soldier happened in France. If a flexible pipe is not available for the food pipe activity, you can make one with a plastic sheet. Take a one-foot-long and six-inch-wide piece of plastic. Roll it into a hollow tube and either sew the edge or seal it by burning. This will serve well as the food pipe. Some students can do this activity as a demonstration. All the other activities can and should be done by all students for themselves. Chapter 1 FOOD FOR HEALTH Why do we have to eat food every day? Food is important for us. We all need food to work, play and study. We need food to stay healthy. We need food to grow and fight diseases. Make a list of all the kinds of food that you ate yesterday. As you have learnt in Class 3, different foods have different nutrients. Different nutrients help our bodies in different ways. How they do so? Some nutrients give us energy. They are called carbohydrates and fats. People doing more work or sports need more energy foods. Other nutrients help to build our bodies and are called proteins and minerals. Then there are nutrients that protect us from getting ill and help us fight diseases. They are called protective nutrients, such as vitamins and minerals. wheat Carbohydrates rice barley sugar Fats nuts butter Proteins meat milk eggs pulses banana Vitamins and Minerals potato tomato seabuckthorn spinach apple apricot carrot Balanced Diet The food we eat is called our diet. If we eat only one type of food, we will become weak or ill. Therefore, we should eat enough of all kinds of nutrients (carbohydrates, fats, proteins, vitamins and minerals). This good mix of food to meet all the needs of the body is called a balanced diet. Healthy Diet Pyramid sugar Eat least oil butter Eat moderately meat eggs milk fish dal cheese nuts curd Eat most chicken vegetables cereals bread fruit a. Look at the list of foods that you ate yesterday. Make a chart like the one below. What kind of nutrients does each food contain? Tick mark the nutrients as shown in the table below. List of Foods khambir thukpa Carbohydrate Fats Proteins and Minerals Vitamins ü ü ü ü Do you have at least one tick in each column? If so, you ate a balanced diet yesterday. b. Students are divided into teams of two or three. Each team plans a balanced diet for a day (breakfast, lunch and dinner) and then shares its menu with the class. Discuss whether it is balanced, or what is missing to make it a balanced diet. Staying Healthy Most of the food we eat is cooked. Cooking helps to kill any germs that may be in the food. It also makes it soft, tasty and easy to digest. However, cooking destroys some of the vitamins in the food. So, along with cooked food, we should eat some raw foods like turnips, radish, carrots and tomatoes every day. Sprouts for Winter Here is something you can do, especially in winter when there are not many fresh vegetables: take some local peas and soak them overnight. Use slightly warm water in winter. You will find the seeds become big as they absorb water. Rinse them in warm water daily but do not leave them soaking. Keep them in a thin, wet cloth until you see that the root has developed. These are called “sprouts” and are very good for you. In order to sprout, the seeds need to be moist and warm. They will die if they freeze, get too hot, soak and rot, or dry out. You can also sprout green moong dal and channa. Any sprouts mixed with other raw vegetables make a very healthy salad! water sprouts swollen peas peas peas peas tied in a cloth mixed salad Are all foods good for health? Play the game of snakes and ladders, shown on the back cover, to find out. Food for Health Don’t forget water! Besides food, safe water is also very important. What will happen if you do not drink enough water? Your food will not be digested well. You will get dehydrated, and you won’t have energy to work or play. More than half of your body is made up of water. So never forget to drink water. At least 6 to 8 glasses every day! What is safe water? A few ways to keep your water safe for drinking and cooking: 1. Boil the water well to kill germs. (In cities, chlorine is added to the water to keep it germ free.) 2. Store clean and boiled water in a clean container with a lid. Put the lid back on every time after use. 3. Always use a long-handled dipper to take water out of the container. EXERCISES Oral/Written Work 1.

GLOSSARY Chapter 6 WILD ANIMALS OF LADAKH Which animals can you recognise on the previous pages? Make a list. a. Which of these animals fly? b. Which animals have hair on their bodies? c. Which of the animals lay eggs? d. Name the animals you see near your village or town. e. Which of these animals eat insects? f. Do any of these animals have four wings? As you can see, animals are different from each other. Some fly and some cannot; some lay eggs and some do not, and so on. Based on these differences, the world of animals is divided into different groups. We will now study some of these groups. MAMMALS Mammals are animals that give birth to live babies and feed them on their own milk. People, cows, cats and wolves are all mammals. Most mammals have hair on their bodies. Some have a lot of hair like the yak, and some have little hair like us! Mammals do not lay eggs. Here are some mammals found in Ladakh. Snow Leopard (Schan) The snow leopard lives in very steep and rocky mountains. People interested in animals live for many months in tents to learn about the snow leopard. This is not easy as the animal is very difficult to see. It has a light grey coat with black markings. This sometimes makes it look like a rock on the mountainside until it moves! The snow leopard has a long and bushy tail. In winter the leopard curls its tail around itself like a blanket. It usually eats wild sheep and goats such as the blue sheep and the ibex. It also eats other smaller animals such as marmots. Wild Animals Otter (Chusram) Otters are playful animals that live along the Indus, the Shayok and the Siachan Rivers. Otters are good swimmers. They can be seen diving into the water and chasing one another. Their main food is fish. Marmot (Phiya) Could you sleep through the whole winter? No? Well, a small animal called the Marmot does that! Marmots sleep through the winter in underground holes called burrows. In summer when there is plenty of grass, they come out of their burrows and spend most of their day eating! By autumn they are very fat and are ready to pass the winter months without any food. Marmots can be found in many places, including Changla and Khardong-la. Have you heard marmots scream? When they feel that they are in danger, they stand up and let out a sharp whistle to warn other marmots. In seconds, they all run for safety into their burrows and disappear. Wild Goats and Sheep (Ridaks) Urial (Shapo) Argali (Nyan) Blue Sheep (Napo) Ibex (Skyin) Look at these pictures of some male wild goats and sheep found in Ladakh. Earlier there were large numbers of these animals, but nowadays we find very few of them. In fact, there are only about 200 argali and about 1500 urial left. You may have seen the horns of one of these animals in the gonpa, or at the base of a chorten. The females are smaller than the males and have smaller horns. Many people in Ladakh call all wild goats and sheep ridaks. However, as you can see there are different kinds of ridaks. Describe the horns of each male and show how each one is different from the other. For example, the horns of the blue sheep look like a motorcycle handlebar! Tibetan Antelope (Tsos) This antelope is found in the very high mountains of Changthang. It can be recognised by its long, thin, pointed horns. People have killed this antelope for its fine wool. The wool was used to make very expensive tsoskul shawls and scarves, called shahtoosh. As there are less than 500 antelopes left in Ladakh, the government has banned the killing of the animal and the selling of tsoskul shawls. Talk to the elders in your village. Ask them about the mammals they have seen. Make a large chart for your class as shown: Name of mammal Where was it seen? Is it seen nowadays? What does it eat? Wild Animals BIRDS Birds are the only animals that have feathers. What are some other characteristics of birds? Do you know that there are more than 340 different kinds of birds in Ladakh? Let’s see how many of them you know. Beaks and How They Are Used Birds have special mouths called beaks. The shape and size of the beak suits what the bird feeds on. Look at the different beaks below. The black necked crane (cha trhung trhung) searches for roots, insects, and fish in wet muddy soil. Its beak is long and pointed. It is our state bird. The golden eagle (laknak) cuts and tears the flesh of animals. It has a beak that is sharp and curved. The rosefinch (ichu marpo or idmar) eats seeds and berries. Its beak is short and heavy. Magpie (kasrang-butit or cha trhawo) Chakor (srakpa) Bar-headed goose (ngangpa) Himalayan griffon (thangkar) Here are a few birds in Ladakh. Look at their pictures carefully. Then answer the following questions. 1. Which of these birds is a water bird? 2. Look at the magpie’s illustration carefully. How many colours does this bird have? Name them. 3. Which bird is sand coloured and calls out “Tokorok-tokorok-tokorok”? 4.What markings do you see on the head of the bar-headed goose? 5. What kind of beak does the griffon have? a. a long, straight beak b. a thin, sharp beak c. a curved, sharp beak 6. What do you think the griffon eats? a. seeds b. meat c. insects 7. This bird is the size of a hen. You can see it walking and running on the ground looking for seeds. Which one is it? Wild Animals (b) (c) (a) (d) 8. Match each bird to one of the nests shown above: chakor, bar-headed goose, griffon and magpie. REPTILES Reptiles are animals with scaly skins. They lay eggs. They are cold blooded, which means that when it is hot outside their body temperature gets warmer and when it is cold outside their body temperature gets colder. Ladakh has a few species of lizards and snakes. Himalayan Rock Laudakia (Sgalchik or Ltsangspa) Have you seen a lizard sitting on a rock enjoying the warmth of the sun? Sometimes you can see it move its head up and down. If it sees you, it will disappear under a rock! This is the Himalayan Rock Laudakia. The female Himalayan Rock Laudakia has orange on the sides of the neck, so some Ladakhis call it the lama sgal- Male rock laudakia lizard chik. The male is larger than the female, with dark marks on its back and a long tail. Some people fear lizards but actually all the lizards found in Ladakh are harmless to people. Female rock laudakia lizard What do lizards eat? Watch one to find out. INSECTS Insects are animals with six legs. Some have wings and some do not. Look at the common insects below. 1. Practise saying their names till you know them. 2. Match each of the sentences below with one of the insects. 3. How many of them are on your chart? a. My legs are very long. I skate on water like you skate on ice. b. I am black and have a hard covering. dragonfly c. We work together and help each other carry food. You can easily water skater see us walking in a line in the fields. d. I am small and round. I have a red body with black spots. e. I sit on your food and could make you ill. f. I look like a butterfly but come out at night. moth caddis-fly beetle g. My back legs are long like oars and they help me swim. I eat insects and fish. h. You call me “helicopter.” I live near ponds and eat mosquitoes and other small insects. i. I am green. I love to eat leaves. When you disturb me, I hop and jump away. j. When I am fully grown, I will have wings. Before that I looked like ladybird caddis-fly a worm and lived in water, and covered myself in a case made of leaves larva or sand and small stones. water boatman grasshopper house fly ant Wild Animals EXERCISES Oral/Written work 1. Name one mammal that a. sleeps through the winter b. usually eats wild sheep and goats c. was killed for its fine wool d. swims very well 2. Name three wild goats or sheep found in Ladakh. 3. Solve the riddles: What am I? a. I am a bird. I call out “Tokorok, tokorok.” I eat seeds. b. I am a protected wild mammal. My wool was used to make shawls and scarves. c. I am an insect. I walk on water. 4. Who eats what? Draw a line to show who eats what. Snow Leopard Grass Lizard Ibex Chakor Flies Otter Grain Marmot Fish Walk around your school in pairs and look for insects with your notebook and pencil. How many different kinds of insects can you find? Be careful not to harm them. Try to find out their names (or make up your own names for them!). The names that you give them could be based on some of their special characteristics. Make a common chart for the class like this one: Name of the insect Ant Drawing Features: colour, size, etc. Black. I found it on alfalfa 5. Name any two differences between: a. Snow leopard and Rosefinch b. Himalayan Rock Laudakia lizard and grasshopper 6. In the word square below, find the names of two mammals, one bird, and three insects. They appear from left to right or top to bottom. D R A G O N F L Y P U C O T T E R Z E R A C T Y U R W K I N B E E T L E L A T T R X O H Y S L M R E A G L E Now that you have found the names of the animals, write two sentences about each. Things to Do Make thumb print animals. Dip your thumb into paint or ink and make a thumbprint on paper. Add a few lines to make it into any animal. Here are a few examples. Have fun! Wild Animals GLOSSARY Environmental Studies Part II for Class IV A Textbook of Social Science for Children of Ladakh Published by J&K State Board of School Education for Operation New Hope Section1 Map Reading Hints for the Teacher Why this section? In social studies, children will have to read maps again and again. But without a simple foundation, many students don’t properly understand how maps relate to reality. Maps can also be useful in our daily lives if we know how to get information from them. Thus this chapter introduces map reading from a very basic level. First the directions are taught and reinforced in relation to pictures and to the immediate surroundings. Then children learn how to read maps with symbols, and how to relate them to real places. In chapter 2, most of the exercises ask the students to complete an unfinished map or key. This kind of involvement will give them a very strong understanding of mapping concepts. Mention that maps are a great source of information if we know how to use them. When we go to a new place, a map helps us find our way around and helps us find the places we need. Maps also help us understand what kinds of things exist in a state or country, etc. Children will have to use many maps in school, and maps will also be helpful in our lives. What is your role? In both chapters, teachers should start each new map or picture activity by asking the children to tell what they see in the picture, what is to the north or south, etc. After some discussion like this, the students should be able to do the exercises themselves easily. They will enjoy drawing in the extra items as instructed in the exercises. Here is an example of a village map made by a teacher. Children will also enjoy making such maps, and will learn map reading skills very thoroughly in the process. Chapter 1 The Directions Do you remember the directions you learnt in class three? Point to the north from your school. Point to the east, then to the south, and then to the west. Where does the sun rise? Where does it set? In the picture below you can see hills. There is a stream down the middle, and a road. You can also see houses, trees, a mosque, a gonpa and a school. The top part of the picture is north. The bottom of the picture is south. The right-hand side is east and the left-hand side is west. Fill in the blanks with names of directions: north, east, south or west. 1. ___________ is to the top of the map. 2. The gonpa is located to the _________ of the village. 3. The school is on the ____________ of the road. 4. The trees are to the ____________ of the stream. 5. The stream flows from ____________ to ___________. Answer the following questions: 1. What things can you see east of the stream? 2. What things can you see north of the road? 3. What is directly north of the school? 4. What is north of the road and west of the stream? Draw the following things on the picture: 1. A stupa to the east of the trees. 2. A shop to the west of the school. 3. A flag east of the gonpa and north of the road. 4. A house north of the road and east of the stream. 5. A community hall east of the mosque and north of the road. This is a map of another village. There are apple orchards, houses, fields, and a pond. Field edges Wall Road House Shop School Apple tree Pond Volleyball court Flag Normally on maps, north is at the top of the page. Draw an arrow on the map pointing north and write a capital N near it. Look at this photograph. You will have to choose which of these three maps could be a map of this place. Look carefully before you decide which map matches the photo. What is in the photo? Where are the road, the houses, the chortens and the fields in relation to each other? Road Stream Building Tree Stupa (chorten)
