Baarish ki har boond keemti
Agar baarish 20 din na ho toh kheton aur nalon ka kya hoga?
Socho pehle… phir dekho jawab
Kheton ki mitti sookh jaati hai, fasal murjha jaati hai, aur zameen ke neeche ka paani bhi kam hone lagta hai. Isiliye baarish ka paani bachana itna zaroori hai.
Dhoop se samundar, nadi aur talaab ka paani bhaap banta hai. Bhaap upar thandi hokar baadal banti hai aur baarish ban kar wapas girti hai. Isko jal chakra (water cycle) kehte hain. Yeh chakra hamesha chalta rehta hai.
Baarish ka kuch paani mitti mein reh kar zameen ke andar jaata hai — wahi paani baad mein kuein aur handpump se milta hai. Cause-effect: agar sab jagah cement hi cement ho, toh paani andar nahi jaa paata aur naali mein beh jaata hai.
Isliye log chhat ka baarish ka paani tank ya gaddhe mein jama karte hain — rainwater harvesting. Ghar pe bhi: nal band karke brush karo, baalti se nahao, aur RO ka bacha paani paudhon ko do.
Ghar pe try karo
Do ek jaisi katoriyon mein barabar paani bharo. Ek ko plate se dhak do, ek khuli chhodo. Dono dhoop mein rakho. Shaam ko dekho — kis mein kam paani bacha? Bhaap ban kar paani kahan gaya, socho!
Wow!
Duniya ke saare paani mein se sirf lagbhag 3 pratishat meetha paani hai — baaki samundar ka khaara!
Mummy-Papa ke liye
Aaj brush karte waqt nal band karne ka niyam saath mein shuru kariye aur ek baalti mein bache paani se paudhe seenchiye.
3 sawaal
- Paani bhaap ban kar baadal bane aur phir baarish ho — ise kya kehte hain?
Jawab dekho
Jal chakra. Bhaap, baadal aur baarish ka ghoomta hua raasta jal chakra hai.
- Dhaki katori mein zyada paani kyun bachta hai?
Jawab dekho
Bhaap ban kar kam paani ud paata hai. Dhakkan bhaap ko baahar jaane se rokta hai, toh paani kam udta hai.
- Rainwater harvesting mein kya karte hain?
Jawab dekho
Baarish ka paani jama karke bachate hain. Chhat ka baarish ka paani tank ya zameen mein bheja jaata hai, taaki baad mein kaam aaye.
