Making a list of items may take a lot of time if there are many items. Hence, it is necessary to use a pictograph. Pictograph: Listing the different data items using picture symbols is called a pictograph. To read a pictograph, we: a) look at the given key. b) multiply the given number of pictures with the value of the key. Key: A key on a pictograph tells us how many objects each picture stands for. Consider these examples. Example 1: If = 10 strawberries, then means how many strawberries? Solution: = 10 strawberries (Given). So, = 3 × 10 strawberries = 30 strawberries 22 2/16/2018 5:20:09 PM 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 56

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. 2 2/16/2018 5:20:10 PM 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 70
ants – anthill honey bees – beehive We can find different types of ants in and around our houses. Certain kinds of ants make their colonies on trees. Why do some insects hide? They hide to protect themselves from their enemies. ant colony on a tree Application Some of the insects that we see in our surroundings are useful to us. Useful Insects Honeybees store honey in their hives. We take this honey and use it in our food and in the preparation of medicines. Beehives are made up of bee wax. We use this wax in medicines. Bee wax is also used to make candles. honey candles made from bee wax Harmful Insects mosquito biting Some insects like flies, mosquitoes and bed bugs are harmful to us. They carry germs. When they bite us, these germs enter our body and make us sick. Insects 3 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 71 2/16/2018 5:20:10 PM

They can also damage our clothes. cockroach eating a bread ants taking stored grains cloth eaten by ants Some insects are harmful to the plants we insects eat and damage the leaf grow. They eat up their leaves and fruits. Amazing Facts Did you know that honeybees and butterflies help the flowers to grow into fruits? Higher Order Thinking Skills (H.O.T.S.) Have you seen spiders in or around your house? Are they insects? No. They are not insects. Unlike insects, they have eight legs. Spiders catch and eat many insects using their webs. You may have seen a spider web in or around your house. It may still be in use by a spider. Or it may be an old and dusty one called a cobweb. Spiders spin webs to catch small insects like flies. The a spider web threads of the web are sticky. So, insects get stuck on the web. Spiders eat those insects. Spiders build their webs between trees or in corners of rooms. Let’s do: Make a spider web with ice cream sticks and thread as shown in the picture. 4 2/16/2018 5:20:10 PM 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 72
Lesson Junk Food 14 Let Us Learn About R junk food. U why junk food is bad for health. A the health problems caused by junk food. H how healthy food is better than junk food. 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. 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 73 5 2/16/2018 5:20:10 PM
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. 6 2/16/2018 5:20:10 PM 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 74

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.

Lesson Animal Shelters 15 Let Us Learn About R shelters of wild and domestic animals. U benefits of shelters to animals. a zoos and national parks. H animal shelters in different seasons. 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. Shelters of Domestic Animals and Pets We build shelters for domestic animals like cows, buffaloes, goats, dogs, horses and so on. 10 2/16/2018 5:20:10 PM 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 78
cowshed kennel stable Shelters of Wild Animals 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 11 Animal Shelters 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 79 2/16/2018 5:20:11 PM
Snakes do not build their shelters. They live in the holes snake hole and burrows made by other animals. We have seen that insects mostly use trees or soil as their shelters. Some of them build shelters for themselves. For example, ants build anthills, bees make hives, and so on. anthill beehive Frogs live in moist places. They can live on the ground or trees. Tigers and lions live in caves. Monkeys live on trees. frogs live on the ground or trees lions in a cave monkey on a tree 12 2/16/2018 5:20:11 PM 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 80
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 13 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 81 2/16/2018 5:20:11 PM
Amazing Facts Jim Corbett National Park is the oldest national park in India. It was set up in 1936 to protect the endangered Bengal tiger. 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 14 2/16/2018 5:20:11 PM 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 82
Lesson Clothes We Wear 16 Let Us Learn About R different types of clothes we wear. U the need for different types of clothes. A clothes in different regions. H how tailors stitch our clothes. Think We wear different types of clothes. Why do we wear clothes? Why do we need different types of clothes? Remembering We wear different kinds of clothes. Do all the clothes that we wear look and feel the same? No. Some clothes are rough while some are soft. Some are thick and some are thin. Some clothes are smooth and silky. The clothes we wear to different places and occasions differ. What do you wear to school? You wear a uniform to school. We wear night clothes when we go to bed. We wear special clothes during parties, festivals and other occasions. 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 83 15 2/16/2018 5:20:11 PM
school uniform nightwear party wear Clothes we wear also vary with the season. We use thin cotton clothes in summer and thick woollen clothes in winter. 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. 16 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 84 2/16/2018 5:20:11 PM
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?

Lesson Types of Transportation 17 Let Us Learn About R the different types of transportation. U transport vehicles. A traffic rules. H people who help us in transportation. Think Reena likes to make paper boats and watch them float on water. Have you ever seen a real boat or travelled in one? How is it different from a car? paper boat Remembering A car travels on land. But a boat travels through water. Are there any other ways by which we can travel? Let us find out. We need to travel for various purposes. 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. 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 87 19 2/16/2018 5:20:11 PM
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. 20 2/16/2018 5:20:11 PM 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 88

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. 22 2/16/2018 5:20:11 PM 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 90

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. 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? zebra crossing Find out. You have seen traffic lights on the roads. These lights 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? traffic signal They are traffic police. They ensure that everybody follows traffic rules. If anyone does not follow the traffic rules, he or she will have to pay a fine.

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. 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 95 27 2/16/2018 5:20:11 PM
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. 28 2/16/2018 5:20:11 PM 51704984_BGM_181910057-Mapple G2_Integrated TB (Eng_Maths_EVS) Term 3_Txt.pdf 96
