I Think Raghav saw a big balloon floating in the sky. His mother told him that it was a hot-air balloon. Raghav wants to know how it went so high in the sky. Do you know how? Hot-air balloon In Class 1 we learnt that air is all around us. But, we cannot see it; it has no colour and no smell. It flows around us. It fills up empty spaces. Let us learn more about air. Properties of air What happens when you fill a balloon with air? It gets bigger in size. This is because the air takes up the space inside the balloon. 48 11/30/2017 4:57:04 PM NR_BGM_Traveller-G2-Textbook-EVS-FY_Txt.pdf 52

When we blow more air, the balloon expands to fill more air inside it. So, the balloon gets bigger in size. Try this! Take two balloons and hang them at the two ends of a hanger. Observe the position of the hanger. Now, replace one of the balloons with a balloon full of air. What do you see? The hanger tilts towards the balloon h i fille i h i oe the reason? The air inside the balloon makes it heavy. So, the hanger tilts towards that side. This shows that air has weight. Try this! Do this activity with the help of your teacher. e lloo fi i o he o h of l o le Now, place the bottle in hot water.

When we burn something such as fire d or er sene a s, it gives out smoke. rnin f arba e also gives out a lot of smoke. e ic es give out smoke and blow up dust in the air.

Care for animals Animals help us in many ways. So, we should take care of them. • We should properly feed our pet animals. When they fall ill, they should be taken to animal doctors. • We should not beat or throw stones at any street animals. • We should provide water and food for stray animals and birds. • We should provide them shelter during rainy days. • We should avoid bursting crackers near them, as the loud sound of crackers is harmful for the animals.

Metro train Truck Van We see different vehicles around us. Let us learn about them in detail. Vehicles and fuels In class 1, we learnt about different kinds of transport. Transport means to carry people or goods from one place to another. Goods are the things that are made or grown in large amounts.

We can travel and move our goods through land, water or air using a variety of vehicles. Can you name the vehicles shown below? ehicles like bicycles, scooters, rickshaws, cars, buses, trucks and so on need roads to run. Trains need railway tracks to run. Ships and boats sail on water. Helicopters and aeroplanes can travel long distances in a very short time. Helicopters need helipads to land and take off. Aeroplanes need airports and runways to take off and land. Have you seen an aeroplane take off? It runs through a runway and then, ? Which vehicle is the fastest: slowly takes off from the ground. auto-rickshaw, train, or aeroplane? How do all these vehicles move? Some of them are moved with the help of humans or animals. or example, rickshaws, bicycles and some types of boats. What about other vehicles? How do they move? They have engines that can run with the help of fuels. We know that we get energy to do work from food. ehicles get energy from fuels. 84 11/30/2017 4:57:07 PM NR_BGM_Traveller-G2-Textbook-EVS-FY_Txt.pdf 88

rom where do we get fuels? Have you seen a Most vehicles need petrol pump? We get different types of fuels from fuel to run. Different these pumps or fuel stations. types of fuels like petrol, diesel, CNG Petrol and diesel are the most common fuels used and LPG are used in vehicles. But, the vehicles that use these fuels to run vehicles. give out smoke, which makes the air dirty. Some vehicles run on electricity. Some vehicles use CNG, LPG and electricity as fuels. These vehicles do not give out smoke. ? Name any two fuels used in cars. Auto-rickshaw that Fuel station (Petrol pump) uses CNG Transport in cities and villages We have learnt about different types of vehicles and the fuels they use. Do we get to see all kinds of transport vehicles in a village? illages have lesser number of vehicles. Also, the type of vehicles people use in villages may be different. In villages, people mostly walk when they have to move around the neighbourhood. They may also move around in carts pulled by bullocks or horses. They may also use bicycles and motorcycles. or long distances, they use buses. In cities, people mostly travel by buses, cars, Bullock cart motorcycles and auto-rickshaws. Some people use their own cars some others hire taxi or cabs with a driver. Some cities have cycle rickshaws.

Taxi Cycle rickshaw Metro train Big cities may have local trains to travel within the city. They may also have special trains called metros. Number and types of vehicles are more in cities. Is this good or bad for us? Let us see. Traffic and its bad effects The number of vehicles on city roads is more than villages. This, sometimes, causes a traffic jam. During a traffic jam, the following problems occur: • People take more time to go from one place to another. traffic a • More fuel gets used. Thus, smoke produced is also more. This makes the air around us dirtier. • People in traffic jams blow horns honk a lot. This causes a lot of noise in Be Amazethat area. This may disturb people and cause stress. A d In 2 1 , a traffic jam on a highway near Beijing kept cars stuck in traffic for more than a week. The traffic jam itself went on for 7 kilometres. 86 11/30/2017 4:57:07 PM NR_BGM_Traveller-G2-Textbook-EVS-FY_Txt.pdf 90

Ways to save fuel and reduce problems that are caused by traffic Traffic jams are caused mainly due to there being more vehicles on roads. How can we reduce the number of vehicles on the roads? • Walking or cycling short distances helps in saving fuel and reduces traffic. • We should use vehicles that can carry more number of people. So, we should use buses more. • We can use shared taxis or cabs to travel. In shared taxis, more than two people going in the same direction can go together. This is called carpooling. • We should use vehicles that run on CNG and electricity. This reduces the smoke around us, which keeps us healthy. ?• Moreover, we should follow traffic rules Can you tell one way on the road.

Mobile phone Telephone Fax machines We use computers and the internet to get or share information. We can send e-mails using the internet. This is an easier way of communication used nowadays in place of sending letters. A person needs to create an e-mail address email-ID to send or receive e-mails. Nowadays, the internet is available at some public places like parks, hotels or movie theatres in the form of Wi-Fi. We can connect to it using our mobile phones also. Do you have an email-ID? You may create your own email-ID with the help of your elders. Communication for recreation We also use communication to enjoy our free time. or example, T s, radios, mobile phones, computers and the internet can be used for recreation. We can see movies, play games and listen to music. We can also read books, shop, chat with our friends and so on. Ways to avoid the misuse of communication devices Mobile phones, televisions, computers and so on are the communication devices that we use. Though all of them help us a lot, we should use them carefully. 1 U sing mobile phones, computers and T s for a long time is harmful to our eyes. If we spend a lot of time on these devices we may skip our studies and not go out to play. This is bad for us. So, we should use them only for a limited time daily. 2 W e should not carry mobile phones to schools or any other places which do not allow them.
