Sahil ki torch jal nahi rahi. Bina soche, wo wahi karta hai jo scientist karte hain. Wo andaaza lagata hai: "Shaayad batteries khatam hain." Phir andaaza jaanchta hai: nayi batteries daalta hai.

Torch ab bhi band hai, to andaaza galat tha. Ye haar nahi! Usne kuch seekha, aur naya andaaza lagata hai: shaayad bulb toota hai. Use bhi jaanchta hai. Jawaab dhoondhne ka ye tareeka scientific method kehlata hai.

Steps ye hain: 1. Dekho kuch dilchasp. 2. Poochho ek sawaal. 3. Andaaza lagao (hypothesis). 4. Jaancho experiment se. 5. Nateeje dekho aur tay karo. Agar andaaza galat tha, wapas jaakar naya lagao.

Achha test fair test hota hai: ek baar mein sirf ek cheez badlo. Ye jaanne ke liye ki beej garam jagah jaldi ugte hain ya nahi, dono gamlon mein same beej, same mitti aur same paani lo, aur sirf jagah badlo. Phir jo bhi farak aaye wo jagah ki wajah se hoga.

Scientist jo dekhte hain wo likhte hain, test dohraate hain taaki pakka ho ki nateeja kismat nahi tha, aur jo mila wo baant-te hain taaki doosre jaanch sakein. Ye sab tum ek copy aur pencil se kar sakte ho!

Explore: steps kram mein lagao, phir ek rahasya suljhaao.

  1. Scientific method ke steps kram mein tap karo.
  2. Ab jasoos bano: har andaaza jaancho aur dhoondo Sahil ki torch kyun nahi jalti.

Yaad rakho

  • Scientific method: dekho, poochho, andaaza lagao, jaancho, nishkarsh. Galat andaaza naye andaaze tak le jaata hai.
  • Fair test mein sirf ek cheez badalti hai. Nateeje likho, test dohraao aur baanto.

Quick check

Divit ka andaaza tha ki patang dor chhoti hone se nahi udi. Usne lambi dor try ki, par ab bhi nahi udi. Ab kya kare?

  1. Naya andaaza lagaaye aur jaanche
  2. Tay kare ki patang kabhi nahi udti
  3. Kehta rahe ki dor hi problem hai
  4. Sawaal poochhna band kare
Answer

Naya andaaza lagaaye aur jaanche. Galat andaaza bhi kuch sikhaata hai. Naya andaaza lagao (shaayad hawa kam hai) aur jaancho.

Socho

Ira sochti hai ki paudhon ko hara rehne ke liye roshni chahiye. Uska andaaza jaanchne ke liye fair test sochho.

Ek answer

Ek hi tarah aur size ke do paudhe lo, same mitti mein, aur same paani do. Ek ko roshni mein aur ek ko andhere almaari mein hafta bhar rakho, baaki kuch mat badlo. Roz unka rang milao aur likho.

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.
