Questions and Solutions

Question 1

Look at the Picture:
  • What are the different kinds of vehicles that you can see?
What do you think they need as fuel?

Which of the vehicles do you think give off smoke? Put a red mark on those.

Solution:

Observing a typical picture with various vehicles, one might see cars, buses, motorcycles, trucks, and possibly bicycles or auto-rickshaws.

Most of these vehicles, like cars, buses, motorcycles, and trucks, need fuel such as petrol, diesel, or CNG to run. Bicycles do not need fuel as they are powered by human effort.

Vehicles that run on petrol or diesel, such as cars, buses, motorcycles, and trucks, typically give off smoke. These are the ones that would be marked with a red mark.

Question 2

Tell:

Do you ride a bicycle? If yes, where all do you go on it?

How do you come to school?

How do your family members go to work from home?

What problems can we have from smoke coming out of vehicles?

Solution:

This question requires a personal answer based on your experiences. For example:

Yes, I ride a bicycle. I go to the nearby park, to my friend's house, and sometimes to the local market on my bicycle.

I come to school by [mention your mode of transport, e.g., school bus, car, walking, bicycle].

My family members go to work from home by [mention their mode of transport, e.g., car, motorcycle, public bus, walking].

The smoke coming out of vehicles causes air pollution. This polluted air can lead to breathing problems like asthma and coughs in people and animals. It can also make our eyes water and our throats sore. Over time, air pollution can cause serious health issues.

Question 3

Find out:

Which states of India have oil fields?

Besides oil, what else is found deep inside the earth?

Solution:

India has significant oil fields in the states of Assam, Gujarat, and Maharashtra. Some offshore oil fields are also found in the Arabian Sea near Mumbai.

Besides crude oil, many other valuable resources are found deep inside the Earth. These include various metals such as gold, silver, copper, iron, and aluminium. Other important resources include coal, natural gas, and different types of minerals.

Question 4

Write:

What all can vehicles run on?

Solution:

Vehicles can run on a variety of energy sources. Common fuels include:

  • Petrol and Diesel: Used in most cars, motorcycles, trucks, and buses.
  • CNG (Compressed Natural Gas): Increasingly used in buses and cars as a cleaner alternative.
  • Electricity: Used in electric cars, scooters, and some buses, which are charged using electricity.
  • LPG (Liquefied Petroleum Gas): Sometimes used in auto-rickshaws and cars.
  • Hydrogen: Being explored as a future fuel source.
  • Human Power: For vehicles like bicycles.
  • Animal Power: For carts pulled by animals.

Common mistakes

  • Not clearly identifying vehicles that produce smoke.
  • Underestimating the impact of vehicle smoke on health and the environment.
  • Confusing different types of fuels used by vehicles.
  • Failing to connect underground resources to everyday products.

Revision tips

  • Draw pictures of different vehicles and label their fuel types.
  • Make a list of ways to reduce smoke from vehicles.
  • Discuss with family members about different ways to travel to save fuel.
  • Think about what happens if the fuel we use finishes.
