Class 6 Science Chapter 11 NCERT Solutions Hinglish mein: Nature's Treasures

Curiosity (Reprint 2026-27) ke Chapter 11, Nature’s Treasures, ki Activities 11.1 se 11.6, in-text sawalon, “Let us enhance our learning” ke saare 16 sawalon aur Learning further ke kaamon ke jawab. Page numbers book se milte hain. Jo activities aur survey tum khud karte ho, unke jawab mein ye diya hai ki kya milne ki ummeed hai; tumhari list thodi alag ho sakti hai. Short notes: Chapter 11 notes.

Prakriti ke khazaane (pages 207–208)

Prakriti ke aur khazaane: taazi hawa, jharnon aur nadiyon ka paani, dhoop, upjaau mitti, paudhon aur jaanwaron se bhare jungle, chattanein aur minerals, aur coal aur petroleum jaise fossil fuels.

Activity 11.1: saans rokna (pages 208–209)

Zyaadatar log thodi der hi saans rok paate hain, aksar ek minute se kaafi kam, aur jaldi bechaini hone lagti hai: saans lene ki tez ichha hoti hai. Aisa isliye hota hai kyunki shareer ko kaam karne ke liye zaroori oxygen nahi mil rahi. Hum khaane ya paani ke bina kuch din jee sakte hain, par oxygen ke bina kuch minute bhi nahi. (Itni der saans mat roko ki tabiyat kharaab lage.)

Hawa ki gases: nitrogen (78%), oxygen (21%), aur argon, carbon dioxide aur doosri gases (1%).

Activity 11.2: firki banaana (page 210)

Firki pakad ke daudo, ya us pe phoonk maaro, to wo ghoomti hai. Use ghumaati hai wind, yaani chalti hawa. Windmill bhi aise hi kaam karti hai; wind uske pankh ghumaati hai, aur windmills aata chakki chalaane, kuon se paani kheenchne aur bijli banaane mein kaam aati hain. Aur windmill farms (Extra): Tamil Nadu, Rajasthan aur Maharashtra ke alawa Gujarat, Karnataka aur Andhra Pradesh mein bhi badi windmill farms hain.

Paani (pages 211–214)

Khaali bubble ke liye paani ke upyog: khaana pakaana, nahaana, kapde aur bartan dhona, ghar ki safaai, paudhon ko paani dena, jaanwaron ko paani pilaana, fasal ugaana, aur udyogon mein.

Paani ke srot: baarish, nadiyan, naale, jheelein, talaab, kuen, hand pump aur tube well (zameen ke neeche ka paani), jharne (springs), aur baraf aur glacier. Samundar mein Earth ka zyaadatar paani hai, par wo khaara hai.

Activity 11.3, Table 11.1, poori bhari hui:

Kaam	Paani kaise barbaad hota hai	Barbaadi kam karne ke tareeke
Haath dhona	Saabun lagaate waqt nal khula	Saabun lagaate waqt nal band karo
Kapde dhona	Chalte nal ke neeche khangaalna; thode-thode kapde dhona	Balti use karo; ek saath poore kapde dho; aakhri khangaal ka paani pochhe ke liye rakho
Bartan dhona	Nal chalta rehta hai	Tub mein dho; jaldi khangaalo
Shower lena	Lamba shower	Balti se nahaao ya chhota shower lo
Khaana pakaana	Sabzi aur chawal chalte nal ke neeche dhona	Bowl mein dho; wo paani paudhon ko do
Bagbaani	Zyaada paani, dopahar mein, pipe se	Subah ya shaam can se paani do; sirf jadon mein
Daant saaf karna	Nal khula chhodna	Mug mein paani lo

Nishkarsh: chhoti rozmarra ki aadaton se, zyaadatar nal khula chhodne se, bahut paani barbaad hota hai. Parivaar nal band karke, leak theek karke, paani dobara use karke (jaise paudhon pe) aur baarish ka paani ikattha karke paani bacha sakte hain.

Paani ganda karne waale aur insaani kaam: gharon ka ganda paani aur sewage nadiyon-talaabon mein bahaana; factory ka kachra daalna; nadiyon aur talaabon mein kapde, gaadiyan aur jaanwar dhona; aur paani mein kachra aur plastic phenkna. (Extra: kheton ke chemical khaad aur keetnaashak bhi beh ke paani mein ja sakte hain.) Hum kya kar sakte hain: dustbin use karo, paani mein kabhi kachra mat phenko, safaai abhiyaan mein judo aur doosron ko batao ki saaf paani kyun zaroori hai.

Paani bachaane ke tareeke: nal band karo, leak theek karo, paani dobara use karo, balti se nahaao, paudhon ko subah ya shaam paani do, aur baarish ka paani ikattha karo.

Paramparik water harvesting (Extra): bawadi aur vav ke alawa Rajasthan ke johad aur tanka, Tamil Nadu ke eri, Himachal Pradesh ki kuhl naaliyan aur Meghalaya ka bamboo drip system. Apne ilaake ke tareeke badon se poochho.

World Water Day (22 March): ye sabko yaad dilaata hai ki meetha paani anmol aur seemit hai, aur logon ko paani bachaane, saaf rakhne aur sabko surakshit peene ka paani dilaane ke liye prerit karta hai.

Sun ki energy (pages 214–216)

Sun ki garmi aur roshni ke upyog: paudhe khaana banaate hain; kapde, mirch, kachche aam, anaaj aur papad sukhaana; din mein roshni; sardiyon mein dhoop sekna; evaporation se samundar ke paani se namak banaana; solar water heater mein paani garam karna; solar cooker mein khaana pakaana; aur solar panels se bijli banaana.

Gaay waali baatcheet: kiska kathan sahi hai? Surya ka aakhri samjhaana. Bhoomi sahi hain ki gaay ghaas khaakar energy paati hai, aur dhoop mein khade hone se pet nahi bharta. Par ghaas ko khaana banaane ke liye dhoop chahiye, isliye ghaas ki energy Sun se aayi. Gaay ko energy ghaas se milti hai, aur us energy ka mukhya srot Sun hai.

Agar kuch din Sun na dikhe to kya hoga?

1. Din mein bhi hamein bijli ki roshni pe nirbhar rehna pad sakta hai.
2. Paudhe khaana nahi bana paayenge, isliye murjhaane lagenge.
3. Thand badh jaayegi, aur kapde, anaaj aur fasal nahi sookhenge; solar panels aur solar cooker kaam nahi karenge.

Jungle (pages 216–218)

Jungle se milne waali paanch cheezein: lakdi (imaarati aur jalaau), nellikai jaise phal, shahad, jadi-bootiyan aur baans. Aur bhi: gond, masaale, jaanwaron ka chaara aur lakdi se bana kaagaz.

Bada jungle kaatne ke nateeje: jaanwar aur pakshi khaana aur ghar kho dete hain, aur kuch gaayab ho sakte hain; jadon ki pakad na rehne se mitti beh jaati hai; giri pattiyan mitti ko poshan nahi de paatin; phal, lakdi aur dawaaiyan khatam ho jaati hain; aur hawa kam taazi rehti hai. Shuruaat ke liye ek chhoti kavita (English mein):

The old trees fell, one, two and three,
No shade was left for you or me.
The birds flew off, the rains washed land,
Let’s plant again, and lend a hand!

Activity 11.4: mitti ko dekhna (pages 218–220)

Table 11.2, kya mil sakta hai: alag jagahon ki mitti alag dikhti hai. Bagiche ya khet ki mitti aam taur pe gehri bhoori aur naram hoti hai, jadon, sookhi pattiyon, chhote kankadon aur kenchuon ke saath; sadak ke paas ki mitti sookhi, halki bhoori ya sleti, aur ret, pattharon aur kachre ke tukdon se mili ho sakti hai; nadi kinaare ki mitti retili aur khurdari ya chipchipi aur chikni ho sakti hai. Abhi-abhi jote khet ki mitti bhurbhuri, naram aur geeli hoti hai.

• Andaaza aur observation: tumhare andaaze mein wo chhoti cheezein chhoot sakti hain jo dhyan se dekhne pe hi dikhti hain, jaise nanhe keede, baal jaisi jadein aur pattiyon ke tukde.
• Alag jagahein: haan, rang aur banaavat alag hote hain, kyunki mitti mein alag-alag padaarth hote hain.
• Aankh aur magnifying lens: lens alag size ke kan, nanhe keede aur jadon-pattiyon ke tukde dikhaata hai jo aankh se chhoot jaate hain. Kuch jeev tab bhi nahi dikhte.

Mitti chhoone ke baad hamesha haath dho.

Chattanein, minerals aur fossil fuels (pages 220–223)

Chattanein aur minerals ek jagah se doosri jagah kaise jaate hain? Zyaadatar trucks, trains aur jahaazon se, jo diesel jaise fossil fuels se chalte hain.

Activity 11.5, Table 11.3, ek namoona survey:

Gaadi ka prakaar	Indhan
Scooter, motorcycle	Petrol
Car	Petrol, diesel, CNG, ya bijli
Bus, truck	Diesel ya CNG
Auto-rickshaw	CNG, petrol, LPG, ya bijli
Tractor	Diesel
E-rickshaw	Bijli (battery)

Sabse aam indhan petrol aur diesel hain.

Mukhya coal utpaadak States (Extra): Odisha, Chhattisgarh, Jharkhand, Madhya Pradesh, Telangana, Maharashtra aur West Bengal. Inhe India ke naqshe pe mark karo.

Fossil fuels bachaane ke aur tareeke: ek gaadi mein milkar jaana (car pooling), laal batti pe engine band karna, gaadiyon ki servicing karwaana, zaroorat na ho to light aur pankha band karna (kaafi bijli coal se banti hai), aur solar energy use karna.

Hum kaunse resources use karte hain (pages 224–225)

Hawa ka pradooshan kam karne ke vikalp: electric aur CNG gaadiyan, public transport, paidal aur cycle, ped lagaana, solar aur wind energy, kachra aur pattiyan na jalaana, aur lakdi-uplon ki jagah LPG ya natural gas se khaana pakaana.

Activity 11.6, Table 11.4, poori bhari hui:

Kaam	Use hone waale natural resources
Kapde dhona	Paani
Mitti ke khilone banaana	Mitti aur paani; sukhaane ke liye dhoop
Jalaau lakdi ikattha karna	Jungle (lakdi)
Patang banaana	Teeliyon ke liye lakdi ya baans aur kaagaz (jungle se); udaane ke liye hawa
Naashta karna	Paudhon aur jaanwaron se khaana (anaaj, phal, doodh), paani, aur pakaane ke liye LPG jaisa indhan

Let us enhance our learning (pages 227–229)

1. Cheezon ko unke ulte-pulte naamon se milao, aur baanto.

Cheez	Naam	Prakaar
Paani waala nal	atwre = Water (paani)	Renewable
Windmill	ndiw = Wind (hawa)	Renewable
Jungle	refost = Forest (jungle)	Renewable
Chattan	ocrk = Rock (chattan)	Non-renewable

2. Sahi ya galat

• (i) Prakriti ke paas insaan ki zarooratein poori karne ke saare resources hain. Sahi. (Ye zarooratein poori karti hai, laalach nahi.)
• (ii) Machines prakriti mein milne waala resource hain. Galat. Machines human-made resources hain, jo natural resources se bani hain.
• (iii) Natural gas non-renewable resource hai. Sahi.
• (iv) Hawa renewable resource hai. Sahi.

3. Khaali jagah bharo

• (i) Scooter ya bike jaise do-pahiya waahanon mein aam taur pe use hone waala indhan hai (b) Petrol.
• (ii) Renewable resource ka udaharan hai (b) Paani (Water).

4. Coal, natural gas, jungle aur minerals ko baanto.

Renewable: jungle. Non-renewable: coal, natural gas aur minerals.

5. Petroleum non-renewable resource kyun hai?

Petroleum zameen ke andar gehre dabe sookshm jeevon aur paudhon ke avsheshon se laakhon saalon mein bana. Ye seemit maatra mein milta hai, aur ek baar use hone pe khatam; theek samay mein dobara nahi banta. Isliye ye non-renewable hai.

6. Jungle dobara ugaana mushkil hai. Sahi saabit karo.

Ped dheere ugte hain: phal ke ped pe bhi phal aane mein saal lagte hain, aur jungle ko ugne mein aur bhi zyaada. Jungle sirf ped nahi; isme jaanwar, pakshi, keede aur upjaau mitti bhi hain jo ek doosre pe nirbhar hain. Bada jungle katne pe jadon ki pakad na rehne se mitti beh jaati hai, aur giri pattiyan use poshan nahi de paatin, isliye naye paudhon ka ugna mushkil ho jaata hai. Isiliye jungle ko zimmedaari se use karna chahiye, unhe dobara panapne ka samay dete hue.

7. Natural resources use karne waale paanch rozmarra ke kaam, aur kam use kaise karein

Kaam	Resource	Kam use kaise karein
Daant saaf karna	Paani	Nal band karo; mug use karo
Nahaana	Paani	Lambe shower ki jagah balti
School jaana	Fossil fuels	Paidal, cycle ya school bus
Light aur pankha chalaana	Bijli (aksar coal se bani)	Kamre se nikalte waqt band karo
Copy mein likhna	Kaagaz (pedon se)	Dono taraf likho; purani copy rough kaam mein lo

8. Hawa ki wajah se sambhav chaar kaam

Saans lena (hamein oxygen chahiye); windmills se bijli banaana, aata chakki chalaana aur paani kheenchna; patang udaana aur firki ghumaana; aur hawa mein kapde jaldi sukhaana.

9. Apne ilaake ki hariyali badhaana

• July mein Van Mahotsav pe, ya khaas dinon pe, local pedon ke paudhe lagao.
• Chhote paudhon ko paani do aur tree guard se bachao.
• Ghar aur school mein kitchen garden ya gamle lagao.
• Purane pedon ko bachao, aur bina wajah patte, phool ya phal mat todo.
• Saal bhar ka eco-club plan banao aur padosiyon ko batao ki ped kyun zaroori hain.

10. Solar cooker

• (i) Khaana pakaane mein solar energy, yaani Sun ki energy, use ho rahi hai.
• (ii) Fayda: isme indhan nahi lagta, isliye dhuaan nahi hota aur fossil fuels bachte hain. Kami: ye sirf dhoop mein kaam karta hai, isliye raat ya badli waale din use nahi hota, aur khaana pakne mein zyaada samay lagta hai.

11. Bade paimaane pe ped kaatne se mitti ki quality kyun girti hai?

Pedon ki jadein mitti ko thaam ke bahne se rokti hain, aur giri pattiyan sad ke use poshan deti hain. Bahut ped katne pe baarish aur hawa upar ki mitti le jaati hai, aur poshan dene ke liye pattiyan nahi girtin, isliye mitti ki upjaau shakti khatam hone lagti hai.

12. Insaan hawa ko do tarah se kaise pradooshit karte hain, aur ek upaay

Gaadiyon mein fossil fuels jalaane se dhuaan aur carbon dioxide nikalti hai; bijli ke liye coal, aur khaana pakaane ke liye lakdi ya uple jalaane se bhi dhuaan nikalta hai. Ek upaay: apni gaadi ki jagah paidal, cycle ya public transport (ya saaf CNG ya electric gaadiyan).

13. Solar panels, gas stove aur windmill waala parivaar: ek hafte dhoop nahi

Solar panels bijli nahi banaayenge, isliye parivaar ko light aur pankhe ke liye bijli ka koi aur srot chahiye hoga (ya bina bijli guzaara karna hoga). Gas stove chalta rahega, kyunki khaana pakaane ki gas ko dhoop nahi chahiye. Windmill tab tak paani kheenchti rahegi jab tak hawa chale. Aas-paas ke paudhe khaana nahi bana paayenge, aur thand badh jaayegi.

14. Concept map bharo

• Natural resources → Renewable resources: hawa (air), paani (water), jungle (forest).
• Natural resources → Non-renewable resource → Fossil fuels: coal, natural gas, petroleum.

15. Udyogon aur ghar ke liye ped kaatna: kya ye sahi hai? Chhoti report

Report English mein (jaisa exam mein likhte hain):

Should we cut trees for industries and housing?

Our town needs wood, paper and land for new homes and factories, which also give people jobs. But trees give us fresh air, shade, fruits and medicines, are home to birds and animals, and hold the soil together. A forest takes many years to grow back, and the Chipko movement showed how much people value their trees.

Conclusion: cutting trees on a large scale is not justified. Only trees that truly must go should be cut, and for every tree cut, several new ones should be planted and cared for. Industries should recycle paper and use other materials where possible, and houses should be planned so that old trees are saved.

16. School mein kam paani use karne ka plan

1. Survey: students ki ek team har nal, tanki aur toilet mein leak dhoondhe aur note kare ki paani kaise use hota hai.
2. Theek karo aur yaad dilaao: tapakte nal theek karwao, aur har nal ke paas “Nal band karo” ke board lagao.
3. Dobara use karo: botlon mein bacha paani aur water purifier ka nikla paani paudhon aur pochhe ke liye ikattha karo.
4. Baarish ka paani: school se kaho ki chhat ka baarish ka paani tanki ya recharge pit mein ikattha kare.
5. Water monitors: har class monitors chune jo break ke baad nal check karein; nateeje prarthana sabha mein batao, khaas kar World Water Day (22 March) pe.

Mahaul ki kaise madad hogi: meetha paani seemit hai, isliye bachaane se logon, paudhon aur jaanwaron ke liye zyaada bachega; rainwater harvesting zameen ka paani bharta hai; aur kam paani pump karne se bijli bachti hai.
