Higher Order Thinking Skills (H.O.T.S.) In our daily life, we do many activities and say that we have done some work. But in science, work is not done in every activity. Here are a few pictures. Identify the objects that are moving and those that are not moving. Tick mark the pictures where some work is done. Work is done when things move from their place. falling leaf moving car girl sitting with books on her head Measuring work can sometimes be tricky. For the work to be done, the pushing the wall position of the object should change from one point to other. If you push the wall with all your energy but the wall doesn’t move, no work has occurred. This is because the wall did not change its position. Sometimes, we may apply a lot of force to move something. But if things don’t move on putting force, then it means that no work is done.

Lesson Forms of Energy 17 Let Us Learn About R energy and its sources. u forms of energy. a uses of energy. h saving energy. Think We need energy to do any work. We get energy from the food we eat. Have you ever wondered what energy is? Where does this energy come from? Remembering Do your parents tell you to drink milk or eat vegetables to get boy kicking football with force energy? We hear the word energy often. What do you do to kick a football? We have learnt in the last lesson that we need force to move, stop or change the shape of an object. We put force on the ball to move it. To put force, we need energy. So, all types of forces have some energy linked with them. Where does the food we eat get the energy from? 14 NR_BGM_9789386663368 MAPLE G04 INTEGRATED TEXTBOOK TERM 3_Text.pdf 102 1/7/2019 3:00:23 PM

The Sun is the basic source of energy on the Earth. The energy we get from the Sun is called solar energy. We can feel the solar energy in the form of light and heat. Plants use this energy to make their food and store it in different plant parts. Some energy is used for the growth of the plant. When we eat plant parts, we get the energy stored in plants. Other than Sun, there are some other energy plants using solar kid eating food for sources. Let us recall what they are: energy energy • W here do vehicles get the energy to run? They get the energy from fuels. • The wind is another source of energy. • Moving water is also an important source of energy. Some sources of energy like the Sun, wind fuel as energy source trees swaying due to the wind and water are not limited, while other sources like fuels are limited. They may get over someday. We must save all kinds of energy sources. Think, can we hold the energy in our hands? Try to hold the wind flowing water as energy or hold the running water from the tap. We cannot hold an energy source energy. Energy has no shape. Understanding We have learnt that we get energy from different sources. Now, let us learn about different forms of energy using some examples. 1) Do you find any difference between day and night when theatre with few lights there are no bulbs or tube lights? It is the presence of light. When you go to the theatre to watch a movie, is it easy for you to find your seats? It is dark until the movie starts. Light is the form of energy we can see. 2) Rub the palms of your hands 10–15 times. Now, quickly touch your eyes with your palms. What do you feel? We can feel the warmth. This form of energy is heat. rubbing the palms Forms of Energy 15 NR_BGM_9789386663368 MAPLE G04 INTEGRATED TEXTBOOK TERM 3_Text.pdf 103 1/7/2019 3:00:23 PM

3) Try blowing on a notebook from place palms on eyes wind used to blow a balloon the side. What happens to the pages of the notebook? Think, about what you do when you want to blow a balloon. The wind energy from your mouth made the pages move and the balloon expand. 4) Look at the electric bulbs and fans in your classroom. Where do they get the energy to work? They use electricity or electrical energy. 5) Throw your eraser slowly towards the roof. Did it stop near the roof or the floor? Gravity pulls everything down. Application We need energy to do work, whether sitting, standing, running or sleeping. We need energy: • for our body to do different work. • to light up bulbs, tube lights and so on. • to cook food. • to run vehicles. • to use phones, televisions, computers and so on. • to cool or heat homes and offices using fans, heaters and coolers. Amazing Facts Have you seen lightning during the rainy season? It is the natural form of electricity. It is very powerful. It can burn everything on its way. During lightning, we should avoid standing under a tree. lightning 16 1/7/2019 3:00:23 PM NR_BGM_9789386663368 MAPLE G04 INTEGRATED TEXTBOOK TERM 3_Text.pdf 104

Higher Order Thinking Skills (H.O.T.S.) It is important to save or conserve energy. Some of the easy ways to save energy are: 1) Turn off fans, lights and other electrical devices when not in use. 2) Lots of energy is used in making paper and plastic. So, we should recycle these things to make newspapers, bottles and so on. We should not waste paper from our notebooks. We should also try to use less plastic. We should use jute and paper bags instead of plastic bags. 3) We should use renewable energy more than non-renewable energy.

Remembering HOW DO WE LEARN ABOUT THE PAST? History is the study of the past. We learn about history from people, objects, materials and written stories of the past. These are called sources of history. We need to look at different sources to know and understand the history of a country. Some of the sources could be remains of very old cities, articles used long ago, stories written about kings and queens and monuments. These sources have helped us to learn about ancient civilizations that existed thousands of years ago. Example: the Indus Valley Civilization, that existed approximately 5000 years ago. It was discovered by archaeologists in the 1920s. They have used pots, jewellery, tools, buildings buried under the ground and so on to write the history of this civilization. The people of the Indus Valley Civilization were mostly farmers. Some of them were artists who made sculptures, seals, pottery and so on. There were metal workers who made gold jewellery and bronze figurines. The Indus Valley Civilization is also called the Harappan Civilization because the ruins of this civilization were first discovered in Harappa. MEASURING TIME IN HISTORY In class 3 you have studied that we use timelines to remember and understand the past. A timeline shows the important events of the past in the order in which they happened. Let us now read about how the years are marked on a timeline. towards 5000 BC towards AD 2020 300 BC   200 BC   100 BC   1 BC   1 AD   100 AD   200 AD  300 AD A timeline showing BC and AD years BC is used to number years for events that happened before the birth of Jesus Christ and AD is used for events that took place after his birth. Thus, when events are marked on a timeline, BC and AD are used to number the years. Look at the timeline above to see how the years are marked.

Understanding How are events marked on a timeline? When counting years on the BC-side of the line, older years have greater numbers. In the BC years, as we show events progressing in time (by writing them from left to right), we number the years in descending order. The later events have smaller numbers. Study the timeline below on the life of Alexander the Great who was born before Christ’s birth. See how the years have been marked. THE LIFE OF ALEXANDER 400 BC 300 BC 356 BC 336 BC 326 BC Birth of Crowned Attack on India by Alexander's army Alexander as king This is not the same on the AD-side of the line. After the birth of Jesus Christ, the years are numbered in ascending order. Here, older years have smaller numbers. More recent years have larger numbers. Read about the life of Emperor Akbar in the timeline below and see how the events in his life are marked. THE LIFE OF EMPEROR AKBAR 1500 AD 1600 AD 1542 AD 1556AD 1569 AD Birth of Became Birth of Akbar king of the Akbar's son Salim Mughal (later Emperor Jahangir) Empire Dynasties and empires of India India’s history spans thousands of years. In the past, it was made up of many kingdoms ruled by different rulers. Sometimes, empires were also formed. A group of kingdoms or countries ruled by a single person, a few people or government is called an empire. When the series of rulers or leaders who rule over a kingdom belong to the same family, it is known as a dynasty. Let us read about some great empires and emperors of India.

Higher Order Thinking Skills (H.O.T.S.) NEED TO PROTECT MONUMENTS As we have seen earlier, monuments teach us about the events that happened in the past. They teach us about our history and we must preserve them. However, some people spoil these monuments by writing on them and throwing trash in the areas around them. Monuments are a part of the rich history of our country. Can you discuss with your class and come up with a poster to raise awareness to protect our monuments? Give your poster a slogan too.

Remembering Just as our parents and teachers make rules for us, the government too makes rules for the country. These rules need to be followed by everyone living in the country, including the government itself. THE CONSTITUTION A constitution is a record of rules for the government and the citizens of a country. The Constitution of India is the supreme law of India. The Indian Constitution is the longest written constitution in the world. It is written in both Hindi and English. What does a constitution tell us? A constitution tells us about the following. • rights and duties of the citizens • the way a government should work • roles to be played by the courts and the police How was the Indian Constitution written? The Constitution of India Our constitution was written by Dr B R Ambedkar and a team of very educated leaders of India which included Rajendra Prasad, Sarojini Naidu and so on. They took about three years to write the constitution. The Constitution of India came into force on 26 January 1950. This is the day our country became a republic. So, we celebrate Republic Day on 26 January every year. NATIONAL SYMBOLS National symbols are symbols that represent a country. On 24 January 1950, just two days before India became a republic, the Constituent Assembly adopted 'Jana gana mana' as the national anthem of India.

Lesson Public Facilities 10 Let Us Learn About R public facility and public property. U important public facilities and their functions. A the need to protect public facilities. h the steps to safeguard public facilities. Think Rashi went to her friend’s house. There, she met her friend’s uncle. Chetan Uncle had brought many books for her friend. Chetan uncle: Do you have a library in your school? Rashi: Yes uncle, we go to the library once a week. Chetan uncle: You should then visit the public library in your A library town, Rashi. You will get to see many books there. Rashi: What is a public library, uncle? Chetan uncle: The government provides various facilities for the public. Just as we have transport, hospitals or water, there are libraries for the public as well where anyone can go and read books. There will be a children’s section too. You should ask your papa to take you there. You will surely enjoy your visit. Rashi: Thank you uncle. I will ask Papa to take me.

Q. Who provides various facilities for the public? (A) libraries (B)  schools (C)  the government (D)  Chetan uncle Remembering What are public Facilities? No matter where we stay, we are all dependent on some things in our daily life. We need water for drinking, washing, irrigation and so on. It is necessary to clear the garbage in our neighbourhood every day. We need public libraries to read books. We need roads, street lights, schools, hospitals, parks and gardens. All these are known as public facilities. Since they are provided in public places and for the benefit and use of the public, they are also called public property. Public facilities are important to make our lives easy and comfortable. They address the basic needs of the people. Any society would need these facilities to meet its basic needs. Example: Imagine your town or city without roads or street lights or public transport. Do you not think that would make your life difficult? The most important feature of a public facility is that once it is provided, its benefits can be shared by many people. For example, a school in the village will allow many children to get an education. Understanding Given that public facilities are so important, someone must carry the responsibility of providing these to the people. This ‘someone’ is the local government body. The local government body is meant to ensure that these public facilities are made available to everyone and are well-maintained. If the public facilities are damaged, they have to be replaced or repaired. If you stay in an urban area, the municipalities or municipal corporations are the urban local government bodies responsible for the public facilities. However, if you stay in a rural area, the Gram Panchayat is responsible for the public facilities. Street lights, water supply, playgrounds and so on are some of the public facilities taken care of by municipal corporations. Let us look at a few more examples of public facilities that are found in cities. 14 NR_BGM_9789386663368 MAPLE G04 INTEGRATED TEXTBOOK TERM 3_Text.pdf 122 1/7/2019 3:00:24 PM

Application Protecting public property Public property belongs to all citizens. If public property is destroyed, then each of us loses something valuable. We must use public facilities only as much as we need. We should also see that they are not damaged or spoiled. We get services in the form of street lights, water pipelines, roads, hospitals and so on. They are maintained by the government using our money. We pay the money to the government in the form of different taxes. So if public property is destroyed, it is the people’s money that is being wasted. We need to protect them by following some rules. • We should keep public places clean and beautiful and not litter them with waste. • We should not damage public facilities like public parks, buses and so on. • We should prevent water from being wasted. • We must be careful that books in the public library are not damaged while using them. Let us look at another type of property called private property. We have already learned that public property is owned by the government. However, private property is owned by an individual or a certain group of individuals. For example, a family home and the land on which it is built are private property. No one outside the family has the right to occupy or use them. Higher Order Thinking Skills (H.O.T.S.) You have read about public facilities. Read the two given situations and discuss with your classmates what steps you would take to look after public facilities. 1) You see a public tap on the road near your house.
