Ye chapter 5 lines mein
The Ever-Evolving World of Science, Curiosity Grade 7 ka pehla chapter hai. Ye yaad dilaata hai ki science ek process hai, sochne ka aisa tareeka jo jigyaasa aur anjaan baaton ka swaagat karta hai, aur gehre sawaal poochhne ko kehta hai: cheezein kaise kaam karti hain, ghatnaayein kyun hoti hain aur prakriti kaunse pattern dikhaati hai. Ye saal ke safar ki jhalak deta hai, padaarthon aur bijli se lekar jeevan prakriyaaon, samay, roshni aur aasmaan tak, aur Activity 1.1, Question the Answer, pe khatm hota hai.
Ye chapter kis baare mein hai?
Chapter 1, Grade 6 ke baad Curiosity mein tumhaara phir se swaagat karta hai. Ye kitaab tathyon ka godaam nahi, balki sawaal poochhne, prayog karne aur duniya ko khojne ka nyota hai, patte ke andar ki nanhi koshikaaon se lekar Sooraj aur taaron ki chaal tak. Iske page number ek phadphadaati titli aur oonchi udti kaagaz ki hawai jahaz ke saath chalte hain, jo yaad dilaate hain ki udaan ke saral avlokan se asli prayog hue aur aakhir mein hawai jahaz bane.
Science ek process hai
Science sirf naye tathya dhoondhna nahi hai. Ye sochne ka aisa tareeka hai jo jigyaasa ka swaagat karta hai, sawaal poochhta hai aur jo abhi pata nahi uske liye khula rehta hai. Grade 7 mein sawaal aur gehre hain: cheezein kaise kaam karti hain, ghatnaayein waise kyun hoti hain, aur prakriti ke pattern se hum kya seekh sakte hain? Inke jawab ke liye hum kitaab se, aur kabhi classroom se bhi, bahar nikalkar activities aur prayog karte hain. Aur padho science kaise badalta rehta hai mein.
Jude hue science aur hamaari zimmedaari
Kitaab mein physics, chemistry, biology aur earth sciences ke chapters hain, par sab jude hain: ek kshetra ka vichaar aksar doosre mein koi khoj, ya kam se kam koi sawaal, jagaata hai. Science zimmedaari bhi hai. Insaan ke kaam prakriti aur samaaj se jude hain, aur science paryaavaran ki chunautiyon ka saamna karne aur zyaada sustainable duniya banaane mein madad kar sakta hai.
Saal ka safar
Chapter kitaab ki ek jhalak dikhaata hai. Shuruaat padaarthon se: kuch phal khatte kyun hote hain, aur haldi ka daag dhone pe kya hota hai? Battery, bulb aur taar dhaatu aur adhaatu tak le jaate hain, aur phir badlaavon tak, kuch ulatne waale, kuch nahi. Hum dekhenge ki garmi barf ke tukde ya glacier ko kaise pighlaati hai, aur paani kaise bhaap bankar baarish banta aur zameen mein samaata hai. Phir aate hain hamaare badhte shareer, jaanwaron aur paudhon ki jeevan prakriyaayein, samay ka naap, roshni aur parchhaai, aur aakhir mein Dharti, Chaand aur Sooraj, din-raat aur grahan ke saath. Garmi, samay aur gati, jaanwaron ki jeevan prakriyaayein, paudhon ki jeevan prakriyaayein, roshni aur Dharti, Chaand aur Sooraj ke notes tum abhi padh sakte ho.
Khushi se khojo!
Har chapter tumhaari jaankaari pe aage banta hai aur vaigyanik ki tarah sochne ko kehta hai, aur ummeed ke mutaabik nikle prayog bhi naye sawaal la sakte hain. Chapter Activity 1.1, Question the Answer pe khatm hota hai: sawaalon ke jawab dene ki jagah tum diye gaye jawabon ke liye rachnaatmak sawaal banaate ho. Ise scientist ki tarah sawaal kaise poochhein mein aazmaao, aur har sawaal ke namoona jawab Chapter 1 ke NCERT solutions mein dekho.
