Science isn't just in labs—it's all around us at home! From the water we drink to how we clean our clothes, science helps us solve everyday problems.
This interactive guide will help you explore how science makes our homes healthier and cleaner!
Clean water is essential for drinking, cooking, and washing. Dirty water can contain harmful germs and chemicals that make us sick.
Dangers of Dirty Water:
1. Can contain bacteria that cause diarrhea and cholera
2. May have viruses that lead to hepatitis
3. Could include parasites causing dysentery
4. Might contain chemicals from farming or factories
5. Often has dirt and waste that make it unsafe

Having clean water is essential for health. Let's explore what makes water unsafe and why we need to purify it.
Water gets cleaned naturally through the water cycle. See how it works:
Evaporation
Condensation
Precipitation
Collection
There are several ways to make water clean and safe for drinking and washing. Let's explore the most common methods:
Heating water to 100°C kills germs. Boil for 1-3 minutes.
Passing water through sand, charcoal or cloth removes particles.
Using chlorine or iodine tablets kills harmful microorganisms.
Evaporating and condensing water leaves impurities behind.
You can make a basic filter with common materials:
Materials Needed:
Cleaning clothes involves several scientific steps to remove dirt and stains effectively.
Soap molecules have two parts:
Water-loving head
Oil-loving tail
The oil-loving tails attach to dirt and grease, while the water-loving heads allow slip away with water.
Before modern detergents, people used natural methods:
Wood ash mixed with water creates lye for cleaning.
Natural berries that release soapy saponins.
Used as a scrubbing agent and stain remover.
Build a simple water filter to see purification in action.
