Family, Shelter, and Community - Chhotu’s House: Keeping Homes Clean

Grade 3CBSE

Review the key concepts, formulae, and examples before starting your quiz.

🔑Concepts

A house is a physical structure made of materials like bricks, cement, and wood, but it becomes a 'Home' when a family lives in it with love and care.

Different parts of a house are used for different purposes: the kitchen for cooking, the bedroom for sleeping, and the bathroom for bathing (H2OH_2O is used here).

Cleanliness is vital for a healthy living environment. Regular activities include sweeping, dusting, and mopping the floor with water (H2OH_2O) and disinfectants.

Waste management: Garbage should always be disposed of in a dustbin to prevent the breeding of germs and insects like flies and mosquitoes.

Uninvited guests: Some animals like spiders, rats, lizards, and ants live in our houses without our permission. They often hide in corners or cracks.

Decorating the house: We decorate our homes on special occasions and festivals using items like flowers, lights, and 'Rangoli' to make them look beautiful.

The relationship between hygiene and health can be viewed as: HygienePrevention of Disease\text{Hygiene} \rightarrow \text{Prevention of Disease}.

💡Examples

Problem 1:

Identify the 'uninvited' guests in Chhotu’s house from the following list: Dog, Cat, Spider, Mosquito, Cow.

Solution:

Spider and Mosquito.

Explanation:

Dogs, cats, and cows are usually kept as pets or domestic animals (invited), whereas spiders and mosquitoes enter and live in the house without being invited.

Problem 2:

Why is it important to use H2OH_2O and floor cleaners while mopping?

Solution:

To remove dust and kill invisible germs.

Explanation:

Water (H2OH_2O) acts as a solvent to remove dirt, and cleaners help in disinfecting the surface to ensure the house remains a healthy environment.

Problem 3:

Name two things used to decorate a house during a festival like Diwali.

Solution:

  1. Diyas (lamps) 2. Rangoli.

Explanation:

Festivals are occasions where the community comes together, and we beautify our shelters to express joy and welcome guests.
