🌊 A Journey Through the 8 States of Water! 🌊
(Yes, water is more magical than you think!)
Chapter Preview 🧐
Scene: A sunny day, two friends (Aavi 🧒 and Thirav 👦) sip shikanji (lemonade 🍋) with ice cubes clinking.
Thirav: “Ice feels hard, water feels wet… Are they the same thing?”
Aavi: “Hmm… Let’s find out!”
You: What do YOU think? 🤔

🔍 Activity Time!
Activity 1: Ice vs. Water – Same or Different? ❄️💧
What to do:
- Take an ice cube 🧊 and drop it in a cup
- Leave it on the table
- Observe after 10 minutes
What happens?
– Ice → Water (Woah! Magic? Nope, science!)
Conclusion:
✅ Ice and water are the SAME substance but in DIFFERENT states!
(Draw what you see! 🎨)
Activity 2: The Mystery of Disappearing Water 💨
Ever noticed?
- Puddles vanish after rain 🌧️
- Wet dishes dry up 🍽️
Aavi’s Theory: “Water seeps into the ground!”
Thirav’s Theory: “Water disappears into the air!”
Let’s TEST IT!
- Put water on a steel plate
- Wait… Does it seep through? NO!
- So… where did it go?
Answer: It turned into invisible water vapour (EVAPORATION!).
🌡️ 3 States of Water (Mind-Blown!)
| State | Example | Can it flow? | Shape |
|---|---|---|---|
| Solid ❄️ | Ice cube | ❌ No | Fixed |
| Liquid 💧 | Water | ✅ Yes | Takes container shape |
| Gas ☁️ | Steam | ✅ Yes (spreads everywhere!) | No shape |
Fun Fact: Even your sweat evaporates to cool you! 🏃♂️💨
❓ Quick Quiz!
- What makes clothes dry faster?
- ☀️ Sunlight
- 💨 Wind
- Both (Tick the right answer!)
- Why does a matka (clay pot) keep water cool? – Water evaporates → Cooling effect! 🆒
(Discuss with a friend!)
💧 The Water Cycle – Nature’s Recycling!
- Evaporation (Water → Vapour) ☀️
- Condensation (Vapour → Clouds) ☁️
- Precipitation (Rain/Snow) 🌧️❄️
Draw your own water cycle! (Use arrows ➡️)
💡 Real-Life Science
- Why do fans cool you? (Sweat evaporates faster!)
- Why is rain important? (Refill lakes, rivers, and your water bottle! 🚰)
Pro Tip: Save water! Every drop counts. 💙
🎉 Fun Extras!
🔹 Try This: Rub hand sanitizer – feels cold? That’s evaporation!
🔹 DIY Cooler: Make a pot-in-pot fridge (Ask an adult for help!).
📢 Class Challenge:
“Who can name ALL 3 states of water fastest?” 🏆
📝 Homework (Shh… It’s Fun!)
- Find 5 things at home that evaporate.
- Write a short poem about rain! (Example: “Drip-drop, never stop…”)
🌟 Remember: Water is a SUPERHERO – it changes forms to keep life going!

Class 6 Science: Evaporation and Condensation – Worksheet with Answers
Explore detailed questions and answers from the NCERT 2025–26 Science Chapter on Evaporation and Condensation for Class 6. Learn about water vapour, daily life applications, the water cycle, and environmental responsibility.
🧠 Q1. Which of the following best describes condensation?
Answer: (iv) The conversion of water vapour into its liquid state.
👉 Condensation is when water vapour cools down and becomes liquid. This forms dew, fog, and clouds.
🎨 Q2. In which of the given processes is evaporation very important?
(i) Colouring with:
- (a) crayons
- (b) water colours ✅
- (c) acrylic colours
- (d) pencil colours
(ii) Writing on paper with:
- (a) pencil
- (b) ink pen ✅
- (c) ball point pen
👉 Water colours and ink pens use liquids that dry through evaporation.
🌿 Q3. Why does space around natural grass feel cooler than plastic grass?
Answer: Natural grass releases water through transpiration – a type of evaporation that uses heat from the surroundings, making the air cooler. Plastic grass lacks this effect and becomes warmer.
💧 Q4. Give examples of liquids other than water that evaporate.
- Alcohol
- Perfume
- Acetone (nail polish remover)
- Petrol
- Aftershave
🌀 Q5. How do fans help in drying clothes if they make things cooler?
Answer: Fans move air around, which helps remove humid air near wet clothes. This increases the rate of evaporation even without heat, making drying faster.
🛢️ Q6. Why is sludge left near drains for a few days before transporting?
Answer:
- Evaporation reduces its weight.
- Dry sludge is safer to handle.
- Reduces transport cost.
- Becomes usable manure for fields.
🏠 Q7. What household activities involve evaporation?
- Drying clothes
- Cooking (boiling)
- Ironing
- Sweating
- Water cooling in earthen pots
Understanding evaporation helps us dry things faster, save water, and stay cool naturally.
❄️ Q8. How is water present in solid state in nature?
- Snow
- Ice
- Glaciers
- Icebergs
- Hail
💬 Q9. “Water is our responsibility before it is our right.” – Reflect.
Answer: We must use water wisely, avoid pollution, and educate others about conservation. Only then can we truly enjoy the right to clean water.
☀️ Q10. How can we cool down a bike seat parked in the sun?
- Cover it with a wet cloth – evaporation will cool it.
- Sprinkle water and let it evaporate.
- Use reflective seat covers or park in shade.
