NCERT Solutions for Class 5 EVS Chapter 12 Look at the picture and write:
Q1: What are the different kinds of vehicles that you can see?
Answer:
In the picture, there are several types of vehicles. I can spot bicycles, which are great because they don’t need fuel. There are also cars of different sizes, buses that can carry many people, motorcycles zipping around, and auto-rickshaws, which are pretty common in some cities.
Q2: What do you think they need petrol and diesel as fuel?
Answer:
Well, bicycles don't need any fuel because they run on human energy – that’s why they’re super for short trips and good exercise! The other vehicles like cars, buses, motorcycles, and auto-rickshaws usually need petrol or diesel to go. They have engines that burn fuel to make them move.
Q3: Which of the vehicles do you think give off smoke? Put a red mark on those.
Answer:
The vehicles that probably give off smoke are the cars, buses, motorcycles, and auto-rickshaws. They burn fuel to run, and that makes smoke come out, which isn't good for our air or our lungs.
Q4: Which are the vehicles run without petrol and diesel?
Answer:
The bicycles are the champions here because they don’t need petrol or diesel. They just need a rider ready to pedal!
Q5: What problems do we face from speeding vehicles?
Answer:
Speeding vehicles can be really dangerous. They might cause accidents, which could hurt people and cause a lot of damage. Plus, they make roads unsafe for everyone, especially for people walking or on bicycles.
NCERT Solutions for Class 5 EVS Chapter 12 Tell:
Q1: Do you ride a bicycle? If yes, where all do you go on it?
Answer:
Yes, I love riding my bicycle! I pedal to school when it's sunny, zoom to the park to play, and sometimes I go to the nearby store to pick up snacks.
Q2: How do you come to school?
Answer:
I take the big yellow bus to school. It's fun because I get to sit with my friends and we sing songs on the way!
Q3: How do your family members go to work from home?
Answer:
My dad takes the car because he works far away, and my mom rides her scooter because it's quicker to get through the traffic.
Q4: What problems can we have from smoke coming out of vehicles?
Answer:
Vehicle smoke can make our air dirty. It can make us feel sick, like when we cough or can't breathe so well. It's not good for animals and plants either.
Q5: What kind of problems can we face from the noise of vehicles (honking)?
Answer:
Loud noises from vehicle horns can be really annoying. They can give us a headache, disturb our sleep, and make it hard to concentrate on homework. It's nice when it's quieter and we can hear the birds instead.

Q1: Which states of India have oil fields?
Answer:
Oh, I learned this from a book! The states in India where we can find oil fields are places like Assam, where the big tea gardens are; Gujarat, which is also known for its lions; Maharashtra, where the Bollywood stars live; and Andhra Pradesh, which has a very long coastline.
Q2: Besides oil, what else is found deep inside the earth?
Answer:
There's a whole treasure of stuff inside the earth! There's coal, which we used to use a lot for cooking and in trains. Then there are shiny things like gold, which is used to make jewelry, and diamonds, that are super hard and can cut other things.
We also have metals like iron to make lots of stuff like cars and bridges, copper which is used in wires, and minerals like potassium for farming, and magnesium and zinc, which are used in all sorts of things, even in medicines and sunscreens!
NCERT Solutions for Class 5 EVS Chapter 12 Write:
Q1: What all can vehicles run on?
Answer:
Besides petrol and diesel, vehicles can also zoom around using LPG, which is like cooking gas, and some cars get their go-go from the sun with solar energy! There are also electric cars and scooters that run on batteries, just like how toys work.
Q2: What kinds of problems will we face if the number of vehicles keeps on increasing? For example, more traffic on the road. Talk to your elders and write about it.
Answer:
My grandpa says if there are too many cars and bikes on the road, it can get super crowded, and we might be stuck in traffic for a long time, which is not fun. The air can get dirty from all the smoke, and the loud noises from honking can be bothersome. Also, if everyone's in a hurry, there could be more boo-boos, like crashes and bumps.
Q3: Manju said, “Why doesn’t everyone use a bus?” What do you think, why don’t people travel by bus?
Answer:
I think people might not take the bus because it can be super packed, and you might have to stand really close to strangers, which is not always comfortable. Sometimes, the buses don't come on time, or they don't stop near where people live or work.
Q4: Suggest some ways to deal with the problems arising out of the growing number of vehicles.
Answer:
We could have special days when we only use bikes or walk. Carpooling is a cool idea too — that's when people share a ride. And if more people could ride buses and trains, there would be fewer cars on the road. Maybe we can have bigger and better buses that come more often so people won't have to wait.
Q5: What are the benefits if we switch off the engine of the vehicles at the red light on the road?
Answer:
Turning off the car when we're waiting at the red light can save petrol, which is good for our wallets and the Earth. It also means less smoke to pollute the air, so we can breathe easier, and it's quieter too, which is nice for everyone around.

Q1: What is the price of petrol and diesel in your area?
Answer:
Right now, where I live, the price for petrol is around ₹ 74.46 for each litre, and for diesel, it's ₹ 66.84 per litre.
Q2: Why are the prices of petrol and diesel going up?
Answer:
Petrol and diesel prices keep going up because there's only so much oil under the Earth and it's hard to get. More and more people and cars need fuel, but because it's not easy to make more oil quickly, the prices go up when lots of people want to buy it.
Q3: In one month, how much petrol and diesel is used in your home? What is it used for?
Answer:
The amount of petrol and diesel we use each month changes. It depends on how many trips we make in our car or on the scooter. We use them to get to places like school, work, the market, and sometimes for little trips on the weekends.

Q1: Where all is oil used?
Answer:
Oil has so many uses! It helps to clean our clothes in dry cleaning, lights up our lamps at night, fuels our cars, buses, and even big airplanes. We also find oil in things like plastics and paints that we use every day. Plus, oil helps in running all sorts of machines and keeps our homes warm when used as kerosene and cooks our food as LPG.
Q2: Where is diesel used? Find out.
Answer:
Diesel is really strong and is used to power big machines like the ones on construction sites and farms. It's also the fuel that many trucks, buses, and some cars use to get around because it's good for driving long distances and carrying heavy loads.
NCERT Solutions for Class 5 EVS Chapter 12 Think and Discuss:
Q1: What would happen if you don’t get petrol or diesel for a week in your village or town?
Answer:
If there's no petrol or diesel for a week, it would be super tricky for everyone to get places like school or work. Cars and buses wouldn't run, and even the machines that help build things or farm would have to stop. It might be a bit like in the old days before there were cars, so lots of walking!
Q2: Suggest some ways to save oil.
Answer:
To save oil, we can do things like:
Turn off car engines when we're waiting at traffic lights. It's like a mini-break for the car and saves fuel!
Ride buses, trains, or even carpool with friends instead of everyone taking their own car.
Use energy from the sun or wind, which is like nature's power, instead of oil for electricity.
For short trips, we can use our legs and walk or pedal bicycles, which is also super healthy!

Q1: Have you ever collected dry wood or made cow dung cakes? How are they made?
Answer:
I've collected sticks and twigs for a campfire but haven't made cow dung cakes myself. I know they're made by mixing dry hay with cow dung, shaping them into flat rounds, and leaving them out in the sun to dry.
Q2: Do you know anyone who collects dry wood or leaves to be used for lighting a chulha?
Answer:
Yes, in the countryside, some folks gather dry wood and fallen leaves to light their chulhas for cooking. It's a lot of work but it's how they make their meals.
Q3: Who cooks food in your family? What about other families in your area?
Answer:
My mom is the chef in our house; she makes the yummiest dishes. In other homes I know, moms, dads, and sometimes cooks prepare the food.
Q4: If they cook food using wood or upla (cow dung cakes), what difficulties do they face due to smoke?
Answer:
Cooking with wood or upla can make a lot of smoke, which isn't good to breathe in. It can make people cough, give them teary eyes, and sometimes even cause chest pains or headaches.
Q5: Can Durga use anything else instead of wood? Why not?
Answer:
Durga could use other things like LPG or biogas if it's available. They're cleaner and don't make smoke, but they can be expensive or hard to get in some places.

NCERT Solutions for Class 5 EVS Chapter 12 Find out from your elders
Q1: When they were young, what was then used for cooking food at home?
Answer:
My grandparents told me that when they were young, they mostly used coal or gathered wood for cooking. Some people also made cow dung cakes to use as fuel. It was all about using what was around them.
Q2: In the past 10 years, the use of which cooking fuel has increased in your area? Use of which fuel has decreased?
Answer:
In the last decade, more and more people in my neighborhood started using LPG (that's cooking gas) and electricity to cook their food because it's cleaner and easier. Not as many people use wood and cow dung now because it's messier and smokier.
Q3: Guess the use of which fuel would increase and which would decrease in the next 10 years.
Answer:
I think in the future, even more people will use electricity, maybe from solar panels, because it doesn't make smoke and we can get lots of energy from the sun. LPG will probably still be popular, but fewer people might use wood and cow dung because there are easier ways to cook that don't make so much smoke and are better for the air.
