Electricity is very important for all of us. We need it for our homes, offices, industries, and agriculture.
Make a list of five different ways in which you can save electricity, for instance, switching off fans, ACs, light at home, and in school when these things are not required.

What is the difference between the inner and the outer core?

On an outline map of the world mark any five major industrial centres of the world.

Trace your journey: Imagine you are a cotton boll. Write about your journey from the field to somebody’s wardrobe write about all the stages you had to pass through to become a garment.

We often leave the lights switched on and fans running when we are not in the room. We switch on the air-conditioning even though we don’t really need it. We insist on being dropped to school in the car every day. Thus, we waste valuable energy which is generally produced by burning coal and petroleum. As you know, the burning of these fuels release gases that pollute the atmosphere.
Make a list of the similar things that we do without realizing that we are destroying the environment. Think of the ways that we can behave differently.

Industries cause pollution when the factories that manufacture goods dump their wastes into the water, air, and soil.
Imagine that you are a factory owner. Write down a few ways in which you can reduce the pollution caused by your factory.
