Test mein aksar sawaal dekar jawaab maange jaate hain. Chalo ise ulat dete hain! Mahaan scientist sirf jawaab nahi dete; ve kamaal ke sawaal poochhte hain. Yaad rakho: samajhdaar banne ke liye "kyun" poochhne wala bano.
Jawaab se sawaal: jawaab "Bas aadha kar do!" ke liye sawaal ho sakta hai "Cake barabar kaise baantein?", "Mera nibandh bahut lamba hai", ya "Ye lifaafe mein nahi aa raha". Ek jawaab, kai alag sawaal! Koi sawaal galat nahi, kalpana ko udne do.
Aazmaao: "Bas thoda doodh daalo." Shayad: "Meri chai bahut kadak hai", ya "Ye paint halka kaise karoon?" ya "Aata bahut sookha hai". Jawaab 42 ke liye "32 + 10 kya hai?" jaise seedhe sawaal mat poochho: mazaa ek jigyaasu, rachnaatmak sawaal mein hai jo asli sthiti se jude.
Is kitaab mein tum prayog karoge. Jab nateeja andaaze se mel khaaye, tab bhi wo naye sawaal aur prayog jaga sakta hai. Isi tarah science badalta rehta hai. Zoya ki salah: is saal har "kyun?" ko ek notebook mein likho.
Explore: achchhe sawaal.
- Sawaal sort karo: kaunse khoj ko bulaate hain?
Yaad rakho
- Scientist ki tarah socho: sirf jawaab nahi, jigyaasu sawaal poochho.
- Ummeed ke mutaabik nateeje bhi naye sawaal aur prayog jagaate hain.
Quick check
Science mein achchhe sawaal poochhna kyun zaroori?
- sawaal prayog aur nayi khoj tak le jaate hain
- sawaal sirf test ke liye
- jawaab sawaal se zyaada zaroori
- scientist kabhi sawaal nahi poochhte
Answer
sawaal prayog aur nayi khoj tak le jaate hain. Har khoj ek achchhe sawaal se shuru hoti hai.
Socho
Jawaab hai "Kyunki billi ke daant tedhe the." Iske liye ek jigyaasu sawaal banao.
Ek answer
Jaise: "Gend par billi ke daant ke nishaan ajeeb kyun the?" ya "Billi khaana theek se kyun nahi chaba paayi?" Koi bhi rachnaatmak, mel khaata sawaal chalega.
Practice
Teen levels (easy, medium, hard) ke naye sawaalon se practice karo, kuch hands-on, hints aur hal ke saath. Topic poora karne ke liye pichhle 5 mein se 4 sahi karo.
