Not all objects can form shadows. Let us see which objects can form shadows and which cannot. Some objects allow light to pass through them. They shadows formed due to sunlight do not block the light. So, they do not form shadows. We can see through these objects. For example, glass and water. Some objects allow only some light to pass through them. They can form shadows, but the shadows are not very dark. We cannot see through these objects properly. objects that allow light to pass through them objects that allow only some light to pass through them Some objects do not allow light to pass through them at all. These objects can form dark shadows. We cannot see through these objects at all. For example, your body does not allow light to pass through it. It forms a shadow when light falls on it. We cannot see through our bodies. Other examples are the walls of our houses, a blackboard and so on. objects that do not allow light to pass through them Light and Shadow 47 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___51 / 88 1/24/2018 11:16:15 AM
Some objects can throw back all the light which falls on them. For example, a mirror reflects the light. a mirror throws back all the light Understanding We have seen that a shadow is formed when an object blocks the path of light. Have you ever noticed the path of light? It is a straight line. Shadows are always formed opposite to the source straight path of light of light. If you stand outdoor in the sun, on which side is your shadow formed? It is on the side opposite to the Sun. If the Sun is on our left, the shadow will be on our right side. If the Sun is in front of us, our shadow is formed behind us. If it is above us, our shadow will be below us. shadows are formed opposite to the source of light 1/24/2018 11:16:16 AM 48 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___52 / 88
What do we feel when we stand in the shadow of a tree or a building? We feel cool. Are the shadows formed always of the same sizes as shadows are cool that of the objects? No. They appear in different sizes. What is the reason for this? If the object is close to the light source, the shadow formed is of a bigger size. As the object moves away from the light source, the shadow becomes smaller. different shadows of the same object Application Have you seen your shadow in the mornings? What does it look like? The shadow is long. Have you seen your shadow at noon? What do you find? The shadow is short. Have you seen your shadow in the evenings? The shadow is longer. What happens after sunset? Our shadow disappears after sunset, as there is no sunlight. shadows formed by sunlight Light and Shadow 49 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___53 / 88 1/24/2018 11:16:16 AM
Amazing Facts Storytelling using shadow puppets started thousands of years ago. In this, the characters of the story are placed between the light and the screen. This forms the shadows on the screen. shadow puppetry Higher Order Thinking Skills (H.O.T.S.) Can you guess why we use glass panes to make windows? Why are our spectacles made of glass? We need to see through these objects. Glass does not block light. So we can see through it. What will happen if we use glass glass windows help panes to make the walls of our us see through house? Everything in our house will be seen from the outside. So, we use wood, bricks and stones to make walls. They do not let light pass through walls of the house do them. Hence, we are unable to see through the walls of not let us see through houses. Why do we use sunglasses when we go out in the sunglasses protect our eyes from the bright light Sun? Sunglasses let only some of the sunlight pass through them. Thus, we are protected from bright sunlight. 50 1/24/2018 11:16:18 AM 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___54 / 88
Lesson Air Around Us 11 Let Us Learn About R the air around us. U moving air. a the uses of air. H warm and cool air. Think We breathe air that is around us. Can we see air? Why do you think air is important for us? Remembering Air is all around us. It is like a big blanket that surrounds us. But we cannot see it. We can only feel it. Air has no smell, shape and colour. It does not stay in one place. It moves from one place to another. Let us learn some more things about air. 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___55 / 88 51 1/24/2018 11:16:20 AM
1) Air has weight: Fill two balloons with air, and tie them on a hanger. Remove air from one balloon. The other balloon drops down. This shows that air has weight. two balloons filled with air air is removed from one balloon 2) Air fills up space: Anything that has weight fills up space. As air has weight, it fills up space too. When we blow air into a balloon, it gets bigger in a boy filling up a balloon size. This shows that air needs space. Understanding THE MOVING AIR When we fly a kite, why does it move? Why does a pinwheel spin? These happen due to moving air. Moving air is called the wind. A gentle or a slow wind is called a breeze. All of us enjoy a cool breeze. a girl flying a kite a spinning When the wind is strong and blows very pinwheel fast, we call it a storm. Storms can cause damage to trees and houses. There are different types of storms. • Some storms bring in heavy rain, lightning and thunder. They are called thunderstorms. • Some storms carry dust with them. These storms are called dust storms. • The storms that carry sand are called sand storms. • Storms that bring snowfall are called snow storms. a thunderstorm 52 1/24/2018 11:16:31 AM 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___56 / 88

USES OF AIR 1) All living things need air to breathe. 2) We also need air for burning candle goes out when things. For example, when a covered with a glass burning candle is covered with breathing in air a glass, it blows out after some time. This happens because there is no air left inside the glass to keep the candle burning. 3) Air gives shape to things. tyre, balloon and football filled with air Things like tyres, balloons and footballs get their shapes only after we fill them with air. 4) Air helps the clothes to dry faster. 5) Air helps boats to sail. clothes hung out to dry sailing boat Air Around Us 53 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___57 / 88 1/24/2018 11:16:38 AM
Amazing Facts Air is lighter than water. Things filled with air float on water. That is why swimming tubes help us to float on water. Higher Order Thinking Skills (H.O.T.S.) When the air becomes warm, it becomes light in weight. So, it moves up. If we burn some dry leaves, we can see small things get blown up in the air. Due to the fire, the air becomes warm and moves upward. It carries the small pieces of burnt leaves up. Warm air moves faster than the cold air. Let us do one activity. fire You should take the help of your teacher or parents to do this. Put a balloon on the neck of a bottle. Keep the bottle in a pan of boiling water. What do we see? The balloon increases in size. What will happen if we keep the bottle in a pan of cold water? There is no change in the size of the balloon. Warm air takes more space than cold air. 54 1/24/2018 11:16:38 AM 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___58 / 88

butterfly grasshopper mosquito These small animals are called insects. Life cycle of a butterfly They creep and crawl. They have six eggs legs. Some insects have wings and can fly. For example, a butterfly, bee, mosquito and so on. Ants and termites are examples of insects which cannot fly. Many insects have different stages in their butterfly caterpillar lives. When they hatch from the egg, they look different. They change their shape and size many times before they become fully grown. For example, a butterfly is first in the form pupa of a caterpillar. Then it becomes a pupa. Later it changes to an adult butterfly. Understanding Where do insects live? We can find some insects like ants in the soil. Insects such as honey bees and butterflies are found on plants. Cockroaches are found inside houses. We can find them in cracks of walls, waste water pipes and so on. During the day, they hide in dark corners of the houses. They come out at night. Insects like bees and ants live in colonies. Colonies are groups of insects living together. Have you ever seen anthills or beehives? These are the colonies of ants and honeybees. 60 1/24/2018 11:16:54 AM 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___64 / 88

Think Farhat likes to eat pizzas and burgers very often. But her parents do not allow her to eat those food items. Why do you think so? Remembering We eat a variety of food items every day. Food gives us energy, helps us to grow and keeps us healthy. Some items are tasty but not so good for health. Can you name the food items given in the picture? We all like to have food items like pizzas, burgers, samosa, chaat, noodles, chips, chocolates and so on. We like them because they are tasty. But, these food items contain a lot of sugar, salt, oil, cheese and so on. If eaten often, they are not good for our health. So, such food items are called junk food. It does not give nutrients to our body. 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___67 / 88 63 1/24/2018 11:17:02 AM
Understanding We have seen that junk food contains a lot of sugar, salt, oil, cheese and butter. It is not good for health. Why is it tasty, but not good for health? Let us find out. 1) Junk food is usually not fresh food. Many other say ‘no’ to junk food harmful items are added to it. These things make it tasty and ready to eat. Eating too much of junk food causes health problems. 2) The food that we eat should contain nutrients like vitamins and minerals. They keep us healthy. They help us grow. They also protect us from sickness. Junk food does not contain these nutrients. So, we should avoid eating junk food. We should eat many healthy food items. They should include: • Food that gives us energy, for example, rice and roti. • Food that makes us strong and helps us grow, for example, dal, milk and eggs. • Food that protects us from sickness, healthy food for example, fruits and vegetables. Application Junk food causes many health problems: unwell child 1) Our stomach is not able to break down such food easily. So, we will get stomach problems. 2) It makes us fat, weak and lazy. 3) It affects our growth. 4) Children eating junk food fall ill very often. 64 1/24/2018 11:17:04 AM 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___68 / 88

Activity B2: Carton Bugs Let us make some carton bugs at home. You will need: egg cartons, scissors, paint, paintbrushes, wiggle eyes, markers, pipe cleaners and a hole punch You need to: 1) separate the egg cartons into various sizes using a pair of scissors. Make some that have only one cup, some with two cups and some with as many as four or five(for caterpillars). 2) choose what type of bugs you want to make. One cup works well for a spider; two work well for a bigger insect; three or more work well for a caterpillar. 3) paint your bug in any colour you wish. Let it dry. 4) place the carton upside down once it is dry, so that the bump is on top. Using a single- hole punch, punch holes at the base of the cup where you want the legs. For a spider, punch four holes on each side. (This step should be done under a teacher’s supervision.) 5) thread the pipe cleaners through the holes to create legs. 6) decorate the bugs using wiggle eyes, glitter, feathers and so on.

Think Sam was playing outside his house. He found two little birds chirping on a nearby tree. Suddenly it started to rain. He rushed to reach his house. He wondered, what would happen to those birds. Where would they go to be safe during the rain? Remembering Like us, the animals also need places to live in. The covered space used by animals to live in are called shelters. Let us learn about the shelters of different kinds of animals around us. Shelter s of Dome stic Anim al s an d Pets We build shelters for domestic animals like cows, buffaloes, goats, dogs, horses and so on. 68 1/24/2018 11:17:17 AM 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___72 / 88
cowshed kennel stable Shelter s of Wil d Anim al s Wild animals live in a variety of shelters like caves, burrows, nests and so on. Some of them build shelters. While some use the shelters made by other animals. Birds mostly live on trees. They build nests to lay eggs. Nests are made of grass, twigs, leaves, threads, straw and so on. Twigs are small broken branches and sticks. Nests of all birds are not alike. Some birds do not make any efforts to build nests. For example, pigeons find shelters in gaps in walls, sunshades of windows and so on. twigs nest shelters of pigeons Rats and rabbits live underground in fields. They dig holes and burrows in the soil to live. Rats can also be found near houses and public places. They can make holes in the walls and floors of houses made of mud. rabbits, rats and mice live in burrows 69 Animal Shelters 1/24/2018 11:17:21 AM 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___73 / 88

Understanding Why do animals need shelters? 1) Shelters protect them from the harsh weather: Shelters protect animals from the rain, wind, hot sun and very cold weather. 2) Shelters protect them from their enemies: They help them to hide from the animals who eat them. Shelters also protect the young ones from their enemies. 3) Some animals like birds need shelters to lay eggs and feed their young ones: There are many animals which eat the eggs of birds. So, birds need a safe place to lay their eggs. They build nests in such places where other animals cannot reach them easily. birds use nests to lay eggs and feed their young ones Application You have learnt about the shelters of wild animals. zoo They are their natural homes. national park But sometimes we see wild animals like the lion, tiger, elephant and monkey in a zoo. Zoos are man-made shelters of these animals. We build them. In the zoos, animals get food and are safe from their enemies. But they are not free. They are kept in cages. Some forest areas are protected as national parks to save the animals and their natural shelters. There, the animals can live freely. Cutting trees or killing animals in these areas is against the law. Animal Shelters 71 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___75 / 88 1/24/2018 11:17:26 AM

Bengal tiger Jim Corbett National Park Higher Order Thinking Skills (H.O.T.S.) The shelters of animals do not give enough protection from extreme hot or cold climate. What do animals do on such days? Let us see. Some animals travel to warm places birds travel to faraway places to escape the extremely cold climate. For example, birds fly to faraway places to escape from the cold winters. Some animals go into a deep sleep to escape the cold weather and shortage of food. These animals go to a cave or a burrow to sleep. In a hot climate, some animals go for a summer sleep. They bury themselves in the ground to avoid the heat. For example, crocodiles and some kinds of frogs move underground where it is cold and more moist to sleep. animals go to a deep winter sleep a frog sleeping underground 72 1/24/2018 11:17:30 AM 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___76 / 88

During the rainy season, we wear clothes which easily dry. We use raincoats when we go out in rains. summer clothes winter clothes clothes for rain We may use different types of clothes at the workplace. Certain types of jobs need special clothes. For example, police, doctors and lawyers wear special clothes. police doctor lawyer Understanding Why do we wear clothes? We wear clothes to cover and protect our body. Clothes protect us from heat, cold, rain and dust. 74 1/24/2018 11:17:42 AM 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___78 / 88
Why do we need different types of clothes? Can you go to school wearing your night dress? Or can you sleep comfortably in your school uniform? No. While sleeping, we need soft and loose night clothes to sleep well. For school, we need a well-ironed and clean school uniform. Similarly, the clothes we wear should be suitable for the weather. Summers are hot, so we wear thin cotton clothes. Cotton allows air to pass through it. It soaks the sweat. So, cotton clothes keep us cool in summer. Winters are cold. During winter, we need thick clothes to protect our body from the cold weather. So, we wear woollen clothes. They keep us warm. During the rainy season, we need waterproof clothes. So, we wear raincoats. They are made from plastic or rubber. They do not allow water to get in. They protect us from getting wet in the rains. Why do people use special clothes at work? Special clothes are suitable for the kind of job they do. They also protect them. For example, firefighters need clothes to protect them from fire. Do you know why you all wear uniforms to school? Find out. Application We discussed the need for different types of clothes. Do people at different places wear the same kind of clothes? Let us find out. Traditional clothes differ across the states and regions of our country. For example, in Rajasthan, men wear dhoti, kurta, angarkha and paggar(safa). Women wear long skirts called the ghagra and tops known as kanchli. Kashmiri men and women wear poots and pheran. In Assam, women wear mekhela chadar, while the men wear dhoti and gamosa. People in different regions may wear the same type of clothes in various ways. For example, the way women wear saree is different across regions.

We also need to carry our belongings from one place to another. We can travel and move our goods through land, water or air. These are the types of transportation. Transportation means carrying people or goods from one place to another. We have roadways and railways for transportation through land. 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___81 / 88 77 1/24/2018 11:17:46 AM
Types/means of transportation water land air roadways railways We use the land type of transport to travel short distances. Water and air transport are used to travel to faraway places. Air type of transport is faster than land and water transportation. Understanding For all types of transport, we need vehicles to carry people and goods. Example: car for land transport, boat for water transport, aeroplane for air transport Vehicles have wheels. The number of wheels may differ in different vehicles. Air transport vehicles may also have wings to help them fly. two-wheelers three-wheelers four-wheelers vehicles with more than four wheels 78 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___82 / 88 1/24/2018 11:17:47 AM
Let us learn about the vehicles used in each type. VEHICLES FOR LAND TRANSPORT 1) Roadways: For roadways, we use vehicles like the bicycle, scooter, auto-rickshaw, car, bus, truck and so on. bicycle scooter auto-rickshaw car bus truck All these vehicles need roads to run. Buses pick and drop people at bus stops or bus stations. road bus station 2) Railways: Trains are railway transport vehicles. Trains are of different types. Some of them carry only goods. They are called goods trains. Trains travel faster than road transport vehicles. Trains need railway tracks to run. Trains pick and drop people and goods from railway stations. goods train railway track railway station Types of Transportation 79 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___83 / 88 1/24/2018 11:17:53 AM
VEHICLES FOR WATER TRANSPORT Water transport vehicles include rafts, boats, ships and so on. Ships carry people and goods across the ocean to different countries. Boats and rafts are smaller than ships. ships They can be used to travel shorter distances through water. boats rafts Ships need ports for loading(picking) and unloading(dropping) people and goods. port VEHICLES FOR AIR TRANSPORT Air transport vehicles include helicopters, aeroplanes, hot-air balloons and so on. helicopter aeroplane hot-air balloon 80 1/24/2018 11:17:55 AM 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___84 / 88
Air transport vehicles need special places to take off and land. Planes need airports with runways. Helicopters need helipads. airport with runways helipad Transport vehicles can be for public or private use. For example, trains, buses, flights and auto-rickshaws. Sometimes, people need help urgently. It is called an emergency. Special vehicles are used in such cases. For example, fire brigade, police vans, ambulances and so on. fire brigade police van ambulance Application The rules which we need to follow on the roads are called traffic rules. We need rules on the road so that we can travel easily and safely. You must have seen some sign sign boards boards on the road. You may have also seen some lines and markings on the road. These signs and lines help us to use the roads safely. Types of Transportation 81 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___85 / 88 1/24/2018 11:18:02 AM
What do your parents tell you while crossing a road? They may tell you to cross the road using the zebra crossing. They may also tell you not to run across the road or cross the road in a hurry without looking at traffic lights. Why should we cross the road at the zebra crossing? Find out. You have seen traffic lights on the roads. These lights zebra crossing control the movement of vehicles on road junctions. They have three lights: red, yellow and green. The red light says ‘stop’ to the vehicles. The yellow light says ‘wait till the light is green’. A green light says ‘go’. Have you seen people in uniform near traffic signals? They are traffic police. They ensure that everybody follows traffic rules. If anyone does not follow the traffic rules, he or she will have traffic signal to pay a fine. Amazing Facts Did you know there are some vehicles which can run an amphibious vehicle on roads as well as on or under water? They are called amphibious vehicles. Higher Order Thinking Skills (H.O.T.S.) You have learnt about vehicles. Who run these vehicles? Who takes care of them? The people who drive a car, bus or truck are called drivers. People who fly aeroplanes are called pilots. People who work on ships and boats are called sailors and captains. Many other people work to make transportation easy and safe. Can you list other people who take care of other public transport? 82 1/24/2018 11:18:02 AM 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___86 / 88
Inside the Lab – C Make sure you do these activities only with the help of a teacher or an adult. Activity C1: Papier(paper) Mache Igloo Igloos or ice houses are generally built of snow and ice in very cold places. An igloo is a dome-shaped building, with blocks of snow placed one on top of the other. You will need: all-purpose glue, old newspapers, black and white paints, masking tape You need to: 1) create papier(paper) mache glue by mixing the entire contents of a glue bottle with 1 cup of water 4 in a bowl. Set aside. 2) cut the papers into thin strips. 3) take an inflated balloon and secure it by using a couple of pieces of tape. 4) draw outlines for the bottom of the igloo and the doorway. 5) dip strips into the glue mixture, making sure to completely soak the paper. Remove the excess glue and lay the strips over the surface of the balloon. Try to keep to one layer. It helps to dry quickly. Also, try to have the pieces criss-cross and overlap. 6) make a doorway to the igloo by using a curved mould and applying the same method. 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___87 / 88 83 1/24/2018 11:18:05 AM
7) allow everything to dry and leave it overnight to become hard. 8) deflate the balloon slowly. 9) trim off the marker lines to make the entrance. 10) paint the igloo white. Let it dry. Then, paint a brick pattern using black paint. Activity C2: Traffic Signals Traffic lights are very important in maintaining public safety and order on the road. You will need: red, yellow, green and black construction paper, scissors, glue sticks, markers, an ice cream stick and a circle shaped button or bottle cap to trace circles. You need to: 1) use a circle-shaped button or bottle cap to draw circles on the red, green and yellow papers. 2) cut out the circles. 3) cut a rectangle from the black construction paper. 4) paste the rectangle vertically on the ice cream stick. 5) stick the red circle on the top side, yellow circle in the middle and the green circle at the bottom side of the black rectangle. You can also play the traffic lights game outdoors or indoors if enough space is available. This is how you can play the game: 1) One person calls out the instructions and pretends to direct traffic. The others follow the instructions. 2) There’s a choice of three instructions, all relating to the colour of traffic lights: ‘red’, ‘green’ or ‘yellow’. 3) If ‘red’ is called, everyone must stand very still and silent. 4) If ‘green’ is called, everyone moves around quite fast. 5) If ‘yellow’ is called, everyone moves around in slow motion. 6) Ask students to take turns to direct the traffic and give instructions. 84 1/24/2018 11:18:06 AM 51704904_BGM Policy_9789387653771_Alpine-G2 EVS-FY_Textbook_Text.pdf___88 / 88
