What if it Finishes...?
Class 5 · Environmental Studies
4 ideas in Class 5 Environmental Studies, explained in plain words, with games and quizzes to practise.
Petroleum Takes a Long Time to Form
Part of: Fuel and Resources
Petroleum forms deep underground over a very long time. People locate it with special methods, pump it out and send it to a refinery for separation and cleaning.
Why it matters. Understanding how long resources take to form helps children see why waste matters.
Try it in two minutes
- Compare the time people use fuel with the very long time it takes to form.
- Trace the path from underground oil to a refinery.
- Discuss why oil is not found everywhere.
Try at home. Think of one action at home that could avoid wasting fuel.
Using Fuel Carefully
Part of: Fuel and Resources
Petrol and diesel are limited, so using them carefully matters. Sharing a bus can move many people with fewer vehicles, and switching off an engine during a stop avoids wasting fuel.
Why it matters. Everyday travel choices can affect fuel use and the number of vehicles on roads.
Try it in two minutes
- Compare one bus carrying many riders with many separate cars.
- Ask what happens when an engine runs while the vehicle is stopped.
- Name a problem caused by heavy traffic, smoke or honking.
Try at home. Plan one way your household could share a trip or avoid an unnecessary journey.
Petroleum Products and Their Uses
Part of: Fuel and Resources
A refinery separates petroleum into different materials. The chapter names fuels such as petrol, diesel, kerosene and aircraft fuel, as well as LPG, wax, grease, coal tar, plastics and paints.
Why it matters. Recognising products from one resource helps children notice how widely it is used.
Try it in two minutes
- Name several products made from petroleum.
- Match a familiar use with the product named in the chapter.
- Discuss what could be affected if the resource became scarce.
Try at home. Look at household items and notice which are plastic, without guessing their source unless known.
Household Fuels and Changing Use
Part of: Fuel and Resources
Homes have used fuels such as wood, twigs, cow-dung cakes, kerosene, LPG, coal and electricity. Burning damp wood makes much smoke, and the chapter’s chart compares how common some fuels were in 1976 and 1996.
Why it matters. Fuel choices affect daily work and the air around people, while charts help us compare change over time.
Try it in two minutes
- Name fuels people may use at home.
- Discuss why damp wood creates a difficulty for someone cooking.
- Read a chart value and say what it counts.
Try at home. Ask an adult which cooking fuel was used when they were young.
